The MediaTek MT7921S is a WiFi/Bluetooth combo chip that works over
SDIO. WiFi and Bluetooth are separate SDIO functions within the chip.
While the Bluetooth SDIO function is fully discoverable, the chip has
a pin that can reset just the Bluetooth core, as opposed to the full
chip. This should be described in the device tree.
Add a device tree binding for the Bluetooth SDIO function of the MT7921S
specifically to document the reset line. This binding is based on the MMC
controller binding, which specifies one device node per SDIO function.

====================
pull-request: bpf-next 2024-05-13
We've added 119 non-merge commits during the last 14 day(s) which contain
a total of 134 files changed, 9462 insertions(+), 4742 deletions(-).
The main changes are:
1) Add BPF JIT support for 32-bit ARCv2 processors, from Shahab Vahedi.
2) Add BPF range computation improvements to the verifier in particular
around XOR and OR operators, refactoring of checks for range computation
and relaxing MUL range computation so that src_reg can also be an unknown
scalar, from Cupertino Miranda.
3) Add support to attach kprobe BPF programs through kprobe_multi link in
a session mode, meaning, a BPF program is attached to both function entry
and return, the entry program can decide if the return program gets
executed and the entry program can share u64 cookie value with return
program. Session mode is a common use-case for tetragon and bpftrace,
from Jiri Olsa.
4) Fix a potential overflow in libbpf's ring__consume_n() and improve libbpf
as well as BPF selftest's struct_ops handling, from Andrii Nakryiko.
5) Improvements to BPF selftests in context of BPF gcc backend,
from Jose E. Marchesi & David Faust.
6) Migrate remaining BPF selftest tests from test_sock_addr.c to prog_test-
-style in order to retire the old test, run it in BPF CI and additionally
expand test coverage, from Jordan Rife.
7) Big batch for BPF selftest refactoring in order to remove duplicate code
around common network helpers, from Geliang Tang.
8) Another batch of improvements to BPF selftests to retire obsolete
bpf_tcp_helpers.h as everything is available vmlinux.h,
from Martin KaFai Lau.
9) Fix BPF map tear-down to not walk the map twice on free when both timer
and wq is used, from Benjamin Tissoires.
10) Fix BPF verifier assumptions about socket->sk that it can be non-NULL,
from Alexei Starovoitov.
11) Change BTF build scripts to using --btf_features for pahole v1.26+,
from Alan Maguire.
12) Small improvements to BPF reusing struct_size() and krealloc_array(),
from Andy Shevchenko.
13) Fix s390 JIT to emit a barrier for BPF_FETCH instructions,
from Ilya Leoshkevich.
14) Extend TCP ->cong_control() callback in order to feed in ack and
flag parameters and allow write-access to tp->snd_cwnd_stamp
from BPF program, from Miao Xu.
15) Add support for internal-only per-CPU instructions to inline
bpf_get_smp_processor_id() helper call for arm64 and riscv64 BPF JITs,
from Puranjay Mohan.
16) Follow-up to remove the redundant ethtool.h from tooling infrastructure,
from Tushar Vyavahare.
17) Extend libbpf to support "module:<function>" syntax for tracing
programs, from Viktor Malik.

Pull hardening updates from Kees Cook:
"The bulk of the changes here are related to refactoring and expanding
the KUnit tests for string helper and fortify behavior.
Some trivial strncpy replacements in fs/ were carried in my tree. Also
some fixes to SCSI string handling were carried in my tree since the
helper for those was introduce here. Beyond that, just little fixes
all around: objtool getting confused about LKDTM+KCFI, preparing for
future refactors (constification of sysctl tables, additional
__counted_by annotations), a Clang UBSAN+i386 crash fix, and adding
more options in the hardening.config Kconfig fragment.

latency. It maintains a separate track for sync. users only. This
approach bypasses per-cpu nocb-lists thus sync-users do not depend on
nocb-list length and how fast regular callbacks are processed.
- RCU tasks: switch tasks RCU grace periods to sleep at TASK_IDLE
priority, fix some comments, add some diagnostic warning to the
exit_tasks_rcu_start() and fix a buffer overflow in the
show_rcu_tasks_trace_gp_kthread().
- RCU torture: Increase memory to guest OS, fix a Tasks Rude RCU
testing, some updates for TREE09, dump mode information to debug GP
kthread state, remove redundant READ_ONCE(), fix some comments about
RCU_TORTURE_PIPE_LEN and pipe_count, remove some redundant pointer
initialization, fix a hung splat task by when the rcutorture tests
start to exit, fix invalid context warning, add '--do-kvfree'
parameter to torture test and use slow register unregister callbacks
only for rcutype test.

- The new STMicroelectronics STM32 "firewall" bus driver that is
used to provide a barrier between different parts of an SoC
- Lots of updates for the Qualcomm platform drivers, in particular
SCM, which gets a rewrite of its initialization code
- Firmware driver updates for Arm FF-A notification interrupts

and vendor specific interfaces, and TEE firmware interface
changes across multiple TEE drivers
- A larger cleanup of the Mediatek CMDQ driver and some related bits
- Kconfig changes for riscv drivers to prepare for adding Kanaan

This will add eBPF JIT support to the 32-bit ARCv2 processors. The
implementation is qualified by running the BPF tests on a Synopsys HSDK
board with "ARC HS38 v2.1c at 500 MHz" as the 4-core CPU.
The test_bpf.ko reports 2-10 fold improvements in execution time of its
tests. For instance:
test_bpf: #33 tcpdump port 22 jited:0 704 1766 2104 PASS
test_bpf: #33 tcpdump port 22 jited:1 120 224 260 PASS
test_bpf: #141 ALU_DIV_X: 4294967295 / 4294967295 = 1 jited:0 238 PASS
test_bpf: #141 ALU_DIV_X: 4294967295 / 4294967295 = 1 jited:1 23 PASS
test_bpf: #776 JMP32_JGE_K: all ... magnitudes jited:0 2034681 PASS
test_bpf: #776 JMP32_JGE_K: all ... magnitudes jited:1 1020022 PASS
Deployment and structure
------------------------
The related codes are added to "arch/arc/net":
- bpf_jit.h -- The interface that a back-end translator must provide
- bpf_jit_core.c -- Knows how to handle the input eBPF byte stream
- bpf_jit_arcv2.c -- The back-end code that knows the translation logic
The bpf_int_jit_compile() at the end of bpf_jit_core.c is the entrance
to the whole process. Normally, the translation is done in one pass,
namely the "normal pass". In case some relocations are not known during
this pass, some data (arc_jit_data) is allocated for the next pass to
come. This possible next (and last) pass is called the "extra pass".
1. Normal pass # The necessary pass
1a. Dry run # Get the whole JIT length, epilogue offset, etc.
1b. Emit phase # Allocate memory and start emitting instructions
2. Extra pass # Only needed if there are relocations to be fixed
2a. Patch relocations
Support status
--------------
The JIT compiler supports BPF instructions up to "cpu=v4". However, it
does not yet provide support for:
- Tail calls
- Atomic operations
- 64-bit division/remainder
- BPF_PROBE_MEM* (exception table)
The result of "test_bpf" test suite on an HSDK board is:
hsdk-lnx# insmod test_bpf.ko test_suite=test_bpf
test_bpf: Summary: 863 PASSED, 186 FAILED, [851/851 JIT'ed]
All the failing test cases are due to the ones that were not JIT'ed.
Categorically, they can be represented as:
.-----------.------------.-------------.
| test type | opcodes | # of cases |
|-----------+------------+-------------|
| atomic | 0xC3, 0xDB | 149 |
| div64 | 0x37, 0x3F | 22 |
| mod64 | 0x97, 0x9F | 15 |
`-----------^------------+-------------|
| (total) 186 |
`-------------'
Setup: build config
-------------------
The following configs must be set to have a working JIT test:
CONFIG_BPF_JIT=y
CONFIG_BPF_JIT_ALWAYS_ON=y
CONFIG_TEST_BPF=m
The following options are not necessary for the tests module,
but are good to have:
CONFIG_DEBUG_INFO=y # prerequisite for below
CONFIG_DEBUG_INFO_BTF=y # so bpftool can generate vmlinux.h
CONFIG_FTRACE=y #
CONFIG_BPF_SYSCALL=y # all these options lead to
CONFIG_KPROBE_EVENTS=y # having CONFIG_BPF_EVENTS=y
CONFIG_PERF_EVENTS=y #
Some BPF programs provide data through /sys/kernel/debug:
CONFIG_DEBUG_FS=y
arc# mount -t debugfs debugfs /sys/kernel/debug
Setup: elfutils
---------------
The libdw.{so,a} library that is used by pahole for processing
the final binary must come from elfutils 0.189 or newer. The
support for ARCv2 [1] has been added since that version.
[1]
https://sourceware.org/git/?p=elfutils.git;a=commit;h=de3d46b3e7
Setup: pahole
-------------
The line below in linux/scripts/Makefile.btf must be commented out:
pahole-flags-$(call test-ge, $(pahole-ver), 121) += --btf_gen_floats
Or else, the build will fail:
$ make V=1
...
BTF .btf.vmlinux.bin.o
pahole -J --btf_gen_floats \
-j --lang_exclude=rust \
--skip_encoding_btf_inconsistent_proto \
--btf_gen_optimized .tmp_vmlinux.btf
Complex, interval and imaginary float types are not supported
Encountered error while encoding BTF.
...
BTFIDS vmlinux
./tools/bpf/resolve_btfids/resolve_btfids vmlinux
libbpf: failed to find '.BTF' ELF section in vmlinux
FAILED: load BTF from vmlinux: No data available
This is due to the fact that the ARC toolchains generate
"complex float" DIE entries in libgcc and at the moment, pahole
can't handle such entries.
Running the tests
-----------------
host$ scp /bld/linux/lib/test_bpf.ko arc:

Add Zhaoxin I2C controller driver. It provides the access to the i2c
busses, which connects to the touchpad, eeprom, I2S, etc.
Zhaoxin I2C controller has two separate busses, so may accommodate up
to two I2C adapters. Those adapters are listed in the ACPI namespace
with the IIC1D17 HID, and probed by a platform driver.
The driver works with IRQ mode, and supports basic I2C features. Flags
I2C_AQ_NO_ZERO_LEN and I2C_AQ_COMB_WRITE_THEN_READ are used to limit
the unsupported access.

Since the I2C IP of both wmt and zhaoxin originates from VIA,
it is better to separate the common code first.
The common driver is named as i2c-viai2c-common.c.
Old i2c-wmt.c renamed to i2c-viai2c-wmt.c.
The MAINTAINERS file will be updated accordingly in upcoming commits.

Commit 51c87f0e6c ("dt-bindings: i2c: nxp,pnx-i2c: Convert to dtschema")
converts i2c-pnx.txt to nxp,pnx-i2c.yaml, but misses to adjust the file
entry in ARM/LPC32XX SOC SUPPORT.
Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a

The msm driver is.. gigantic and covers display hardware (incl. things
concerning (e)DP, DSI, HDMI), as well as the entire lineup of Adreno
GPUs (with hw bringup, memory mappings, userspace interaction etc.).
Because of that, people listed as M:/R: receive patches concerning
drivers for any part of the display block OR the GPU. Separate the
latter, as it's both a functionally separate block and is of
interest to different folks.

ARM/VT8500 is marked as Orphan. It includes ehci-platform.c and
uhci-platform.c in its file list, even though uhci-platform.c is included
from uhci-hcd.c and ehci-platform.c is used by several platforms.
Listing those files as part of an orphan platform does not add value,
even more so since they are marked as supported as part of generic ehci
and uhci support. Drop the files from the ARM/VT8500 entry.

1. Basic support for SCMI v3.2 pincontrol protocol
SCMI v3.2 introduces pincontrol protocol which is intended for
controlling pins and their configuration. The pin control protocol
provides commands to:
- List the pins, groups of pins, available functions, and their
association with each other.
- Set the parameter configuration and multiplexing of the pins or
groups of pins
- Optionally request exclusive access to a pin or group of pins.
- Optionally configure the permissions of an agent to access a pin
or group of pins.
These changes adds basic support for the same in the SCMI core layer
and an implementation of the generic scmi-pinctrl driver with associated
DT bindings.
2. Framework support for multiple vendors custom protocols
With the fixed space for vendor protocols, the possibility of having
multiple vendors implementing distinct SCMI vendor protocols with
the same overlapping protocol number is very high and with the need
to support them all in a single kernel image or a module is also high.
In order to implement the same we assume:
- vendor protocols has to be tagged at build time with a vendor_id
- vendor protocols could also optionally be tagged at build time with
sub_vendor_id and implementation version
At the initialisation all the built vendor protocols are registered
with the SCMI core using a key derived from the above tags
3. Logging and tracing improvements
This includes using dev_err_probe() to bail out from probe, adding
message dump traces for bad and unexpected replies and widening of
the tag buffer in trace_scmi_dump_msg to allow diverse tag names
4. Miscellaneous updates or improvements
This includes adding the accessor function get_max_msg_size() used
in pinctl protocol, updation of dt-bindings examples for protocol@13
to promote new bindings and simplification of scmi_devm_notifier_unregister

This introduces a TEE driver for Trusted Services [1].
Trusted Services is a TrustedFirmware.org project that provides a
framework for developing and deploying device Root of Trust services in
FF-A [2] Secure Partitions. The project hosts the reference
implementation of Arm Platform Security Architecture [3] for Arm
A-profile devices.
The FF-A Secure Partitions are accessible through the FF-A driver in
Linux. However, the FF-A driver doesn't have a user space interface so
user space clients currently cannot access Trusted Services. The goal of
this TEE driver is to bridge this gap and make Trusted Services
functionality accessible from user space.

TEE driver for Trusted Services
This introduces a TEE driver for Trusted Services [1].
Trusted Services is a TrustedFirmware.org project that provides a
framework for developing and deploying device Root of Trust services in
FF-A [2] Secure Partitions. The project hosts the reference
implementation of Arm Platform Security Architecture [3] for Arm
A-profile devices.
The FF-A Secure Partitions are accessible through the FF-A driver in
Linux. However, the FF-A driver doesn't have a user space interface so
user space clients currently cannot access Trusted Services. The goal of
this TEE driver is to bridge this gap and make Trusted Services
functionality accessible from user space.

The Qualcomm SCM driver initialization order is improved, to avoid any
potential for a client to find a half-initialized SCM instance.
The handling of download mode bits is updated to not attempt
QCOM_SCM_BOOT_SET_DLOAD_MODE if a io-address for the update is
specified, and that path is changed to perform a read-modify-write to
avoid updating unrelated bits. Error handling is corrected in the
peripheral authentication service (PAS) functions, to release
interconnect bandwidth votes in the case of an error. An unwanted error
print on allocation error is also removed from this code path.
The QSEECOM allow list is marked __maybe_unused to avoid build warnings
when built with !OF. The error handling related to the interconnect API
is cleaned up to avoid handling the impossible IS_ERR() condition.
initcall level is bumped to "core" for cmd-db and rpmh-rsc, as dependent
drivers like regulators, interconnects and clocks are registered at this
level.
Another attempt is made to remove the strncpy() usage in cmd-db, this
time with strtomem_pad() which has the correct characteristics.
The bwmon regmap cache is changed to maple tree.
After an attempt to add missing MODULE_DEVICE_TABLEs to debug drivers,
the intention of not having them automatically load is documented.
Operations on the pmic_glink client list is put under mutual exclusion,
to avoid races when clients are being registered. pmic_glink client
registered after the firmware notification arrived was not informed that
the firmware was up, this is resolved.
More DSPs and the apss subsystem is added to the Qualcomm sleep stats driver.
Checks for in-flight regulator requests in the RPMh RSC driver is
improved to deal with the fact that these occupy multiple registers, so
it's insufficient to just to direct address comparison.
The socinfo drivers learns about X1 Elite and SMB2360 PMIC.
The maintainers entry is split between the linux-arm-msm list and
subset that is maintained in the qcom-soc tree, to avoid some confusion
about maintainership.

Introduce STM32 Firewall framework for STM32MP1x and STM32MP2x
platforms. STM32MP1x(ETZPC) and STM32MP2x(RIFSC) Firewall controllers
register to the framework to offer firewall services such as access
granting.
This series of patches is a new approach on the previous STM32 system
bus, history is available here:
https://lore.kernel.org/lkml/20230127164040.1047583/
The need for such framework arises from the fact that there are now
multiple hardware firewalls implemented across multiple products.
Drivers are shared between different products, using the same code.
When it comes to firewalls, the purpose mostly stays the same: Protect
hardware resources. But the implementation differs, and there are
multiple types of firewalls: peripheral, memory, ...
Some hardware firewall controllers such as the RIFSC implemented on
STM32MP2x platforms may require to take ownership of a resource before
being able to use it, hence the requirement for firewall services to
take/release the ownership of such resources.
On the other hand, hardware firewall configurations are becoming
more and more complex. These mecanisms prevent platform crashes
or other firewall-related incoveniences by denying access to some
resources.
The stm32 firewall framework offers an API that is defined in
firewall controllers drivers to best fit the specificity of each
firewall.
For every peripherals protected by either the ETZPC or the RIFSC, the
firewall framework checks the firewall controlelr registers to see if
the peripheral's access is granted to the Linux kernel. If not, the
peripheral is configured as secure, the node is marked populated,
so that the driver is not probed for that device.
The firewall framework relies on the access-controller device tree
binding. It is used by peripherals to reference a domain access
controller. In this case a firewall controller. The bus uses the ID
referenced by the access-controller property to know where to look
in the firewall to get the security configuration for the peripheral.
This allows a device tree description rather than a hardcoded peripheral
table in the bus driver.
The STM32 ETZPC device is responsible for filtering accesses based on
security level, or co-processor isolation for any resource connected
to it.
The RIFSC is responsible for filtering accesses based on Compartment
ID / security level / privilege level for any resource connected to
it.

Add a new driver for the MSI WMI Platform interface. The underlying
ACPI WMI interface supports many features, but so far only reading
of fan speed sensors is implemented.
The driver was reverse-engineered based on a user request to the
lm-sensors project, see the github issue for details.
The ACPI WMI interface used by this driver seems to use the same
embedded controller interface as the msi-ec driver, but supports
automatic discovery of supported machines without relying on a
DMI whitelist.
The driver was tested by the user who created the github issue.

Virtual Machine Generation ID driver was introduced in commit
af6b54e2b5 ("virt: vmgenid: notify RNG of VM fork and supply
generation ID"), as an ACPI only device.
VMGenID specification http://go.microsoft.com/fwlink/?LinkId=260709
defines a mechanism for the BIOS/hypervisors to communicate to the
virtual machine that it is executed with a different configuration (e.g.
snapshot execution or creation from a template). The guest operating
system can use the notification for various purposes such as
re-initializing its random number generator etc.
As per the specs, hypervisor should provide a globally unique
identified, or GUID via ACPI.
This patch tries to mimic the mechanism to provide the same
functionality which is for a hypervisor/BIOS to notify the virtual
machine when it is executed with a different configuration.
As part of this support the devicetree bindings requires the hypervisors
or BIOS to provide a memory address which holds the GUID and an IRQ
which is used to notify when there is a change in the GUID. The memory
exposed in the DT should follow the rules defined in the vmgenid spec
mentioned above.
Reason for this change: Chosing ACPI or devicetree is an intrinsic part
of an hypervisor design. Without going into details of why a hypervisor
would chose DT over ACPI, we would like to highlight that the
hypervisors that have chose devicetree and now want to make use of the
vmgenid functionality cannot do so today because vmgenid is an ACPI only
device. This forces these hypervisors to change their design which
could have undesirable impacts on their use-cases, test-scenarios etc.
The point of vmgenid is to provide a mechanism to discover a GUID when
the execution state of a virtual machine changes and the simplest way to
do it is pass a memory location and an interrupt via devicetree. It
would complicate things unnecessarily if instead of using devicetree, we
try to implement a new protocol or modify other protocols to somehow
provide the same functionility.
We believe that adding a devicetree binding for vmgenid is a simpler,
better alternative to provide the same functionality and will allow such
hypervisors as mentioned above to continue using devicetree.
More references to the vmgenid specs are found below.

net: intel: start The Great Code Dedup + Page Pool for iavf
Alexander Lobakin says:
Here's a two-shot: introduce {,Intel} Ethernet common library (libeth and
libie) and switch iavf to Page Pool. Details are in the commit messages;
here's a summary:
Not a secret there's a ton of code duplication between two and more Intel
ethernet modules. Before introducing new changes, which would need to be
copied over again, start decoupling the already existing duplicate
functionality into a new module, which will be shared between several
Intel Ethernet drivers. The first name that came to my mind was
"libie" -- "Intel Ethernet common library". Also this sounds like
"lovelie" (-> one word, no "lib I E" pls) and can be expanded as
"lib Internet Explorer" :P
The "generic", pure-software part is placed separately, so that it can be
easily reused in any driver by any vendor without linking to the Intel
pre-200G guts. In a few words, it's something any modern driver does the
same way, but nobody moved it level up (yet).
The series is only the beginning. From now on, adding every new feature
or doing any good driver refactoring will remove much more lines than add
for quite some time. There's a basic roadmap with some deduplications
planned already, not speaking of that touching every line now asks:
"can I share this?". The final destination is very ambitious: have only
one unified driver for at least i40e, ice, iavf, and idpf with a struct
ops for each generation. That's never gonna happen, right? But you still
can at least try.
PP conversion for iavf lands within the same series as these two are tied
closely. libie will support Page Pool model only, so that a driver can't
use much of the lib until it's converted. iavf is only the example, the
rest will eventually be converted soon on a per-driver basis. That is
when it gets really interesting. Stay tech.
* '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
MAINTAINERS: add entry for libeth and libie
iavf: switch to Page Pool

page_pool: constify some read-only function arguments

papr_scm and ndtest share common PDSM payload structs like
nd_papr_pdsm_health. Presently these structs are duplicated across
papr_pdsm.h and ndtest.h header files. Since 'ndtest' is essentially
arch independent and can run on platforms other than PPC64, a way
needs to be deviced to avoid redundancy and duplication of PDSM
structs in future.
So the patch proposes moving the PDSM header from arch/powerpc/include-
-/uapi/ to the generic include/uapi/linux directory. Also, there
are some #defines common between papr_scm and ndtest which are not
exported to the user space. So, move them to a header file which
can be shared across ndtest and papr_scm via newly introduced
include/linux/papr_scm.h.

This driver provides a basic GPIO driver for the Intel Granite Rapids-D
virtual GPIOs. On SoCs with limited physical pins on the package, the
physical pins controlled by this driver would be exposed on an external
device such as a BMC or CPLD. The virtual GPIO registers are an
interface to firmware, which communicates with the external device that
implements the GPIO hardware functionality.

The Analog Device team (Paul Cercueil and Nuno Sa) have been working on
improving high speed device handling. They have had some support in their
own tree for many years, so it is great to see them bring it to upstream.
Some of that is seen here, with the first output device using the
IIO dmaengine infrastructure and a new DAC backend FPGA IP driver.
This makes use of a new set of interfaces to allow backend and
front end driver communication in a fashion that in theory at least
allows for a single driver for a given ADC / DAC independent of
the IP to which is being used to deal with the data bus and DMA aspects
of working with these devices. It is early days for this new
generic way of handling split devices, but as it's kernel internals only
we can merrily change anything about it as a wider diversity of devices
show up and we get a better feel for what works.
Alongside the usual set of new drivers and features we have
the automatic cleanup of fwnode_handle_put() which didn't quite make
it in last cycle. The equivalent DT version was merged by Rob Herring
via the DT binding tree and one patch using that in IIO can also be
found in this pull request. Rob has been making extensive use of that
infrastructure in the DT core which is good to see and provides more
evidence this basic approach is useful.
In some cases, the IIO driver was converted over from DT only to
using the generic firmware description handling of property.h
including using the new macros. The general preference for IIO
is to use this more generic handling where possible - a bunch of other
drivers have been converted this cycle as well.
New device support
==================
adi,ad7173
- New driver supporting AD7172-2, AD7172-4 AD7173-9, AD7175-2, AD7175-8,
AD7176-2 and AD7177-2 ADCs.
- Follow up fix for an accidental use of logic not instead of bitwise.
adi,ad7944
- New driver supporting AD7944, AD7985 and AD7986 pin compatible ADCs.
- Later patch added use of new spi_optimize_message() to reduce overheads
of setting up a reused message.
- Additional changes later in series reduced code duplication.
adi,ad9739a RF DAC
- New driver for this 14-bit 2.5 GSPS DAC via an LVDS interface.
adi,axi-dac
- Support for this FPGA IP used to send data to high performance DACs over
an interface such as JESD204B/C or parallel interfaces. Used in
conjunction with a DAC driver. The initial user is the ad9739a.
The dmaengine-buffer needed various changes to make it bidirectional.

- New driver for this ambient light sensor.
- Fix much later in this pull for an off by 1 error.

in that case but good to clean this up.

- Drop unnecessary casts of other pointer types to void *
docs
- Add missing ABI entry for in_temp_input.
adi,adx345
- General cleanup prior to adding spi-3wire mode.
adi,axi-adc
- Be more flexible and allow minor version changes as these are expected
to be backwards compatible.

for temperatures
- Ensure error handling of regmap calls is consistent within the driver.

Add a tool to generate a picture of the current DAPM state for a sound
card.
dapm-graph is inspired by vizdapm which used to be published on a Wolfson
Micro git repository now disappeared, and has a few forks around:
https://github.com/mihais/asoc-toolshttps://github.com/alexandrebelloni/asoc-tools
dapm-graph is a full reimplementation with several improvements while still
being a self-contained shell script:
Improvements to rendered output:
- shows the entire card, not one component hierarchy only
- each component is rendered in a separate box
- shows widget on/off status based on widget information alone (the
original vizdapm propagates the "on" green colour to the first input
widget)
- use bold line and gray background and not only green/red line to show
on/off status (for the color blind)
Improvements for embedded system developers:
- remote mode: get state of remote device (possibly with minimal rootfs)
via SSH, but parsing locally for faster operation
- compatible with BusyBox shell, not only bash
Usability improvements:
- flexible command line (uses getopts for parsing)
- detailed help text
- flag to enable detailed debug logging
- graphviz output format detected from file extension, not hard coded
- a self-contained shell script
Usage is designed to be simple:
dapm-grpah -c CARD - get state from debugfs for CARD
dapm-grpah -c CARD -r REMOTE_TARGET - same, but remotely via SSH
dapm-grpah -d STATE_DIR - from a local copy of the debugfs
tree for a card

The AD9739A is a 14-bit, 2.5 GSPS high performance RF DACs that are capable
of synthesizing wideband signals from DC up to 3 GHz.
A dual-port, source synchronous, LVDS interface simplifies the digital
interface with existing FGPA/ASIC technology. On-chip controllers are used
to manage external and internal clock domain variations over temperature to
ensure reliable data transfer from the host to the DAC core.

Support the Analog Devices Generic AXI DAC IP core. The IP core is used
for interfacing with digital-to-analog (DAC) converters that require either
a high-speed serial interface (JESD204B/C) or a source synchronous parallel
interface (LVDS/CMOS). Typically (for such devices) SPI will be used for
configuration only, while this IP core handles the streaming of data into
memory via DMA.

Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:
In some cs42l43 systems a couple of cs35l56 amplifiers are attached
to the cs42l43's SPI and I2S. On Windows the cs42l43 is controlled
by a SDCA class driver and these two amplifiers are controlled by
firmware running on the cs42l43. However, under Linux the decision
was made to interact with the cs42l43 directly, affording the user
greater control over the audio system. However, this has resulted
in an issue where these two bridged cs35l56 amplifiers are not
populated in ACPI and must be added manually. There is at least an
SDCA extension unit DT entry we can key off.
The process of adding this is handled using a software node, firstly the
ability to add native chip selects to software nodes must be added.
Secondly, an additional flag for naming the SPI devices is added this
allows the machine driver to key to the correct amplifier. Then finally,
the cs42l43 SPI driver adds the two amplifiers directly onto its SPI
bus.
An additional series will follow soon to add the audio machine driver
parts (in the sof-sdw driver), however that is fairly orthogonal to
this part of the process, getting the actual amplifiers registered.
My old NEC address has been removed, so update MAINTAINERS and .mailmap to
map it to my gmail address.

Add two compatibles for binman entries, as a starting point for the

Note that, after discussion on v2, we decided to keep the existing
meaning of label so as not to require changes to existing userspace
software when moving to use binman nodes to specify the firmware
layout.
Note also that, after discussion on v6, we decided to use the same
'fixed-partition' schema for the binman features, so this version
adds a new 'binman.yaml' file providing the new compatibles to the
existing partition.yaml binding.

.. so this can start re-using existing lib.sh infra in next patches.
Several of these scripts will not work, e.g. because they assume
rp_filter is disabled, or reliance on a particular version/flavor
of "netcat" tool.
Add config settings for them.
nft_trans_stress.sh script is removed, it also exists in the nftables
userspace selftests. I do not see a reason to keep two versions in
different repositories/projects.
The settings file is removed for now:
It was used to increase the timeout to avoid slow scripts from getting
zapped by the 45s timeout, but some of the slow scripts can be sped up.
Re-add it later for scripts that cannot be sped up easily.

Add a script which produces a Flat Image Tree (FIT), a single file
containing the built kernel and associated devicetree files.
Compression defaults to gzip which gives a good balance of size and
performance.
The files compress from about 86MB to 24MB using this approach.
The FIT can be used by bootloaders which support it, such as U-Boot
and Linuxboot. It permits automatic selection of the correct
devicetree, matching the compatible string of the running board with
the closest compatible string in the FIT. There is no need for
filenames or other workarounds.
Add a 'make image.fit' build target for arm64, as well.
The FIT can be examined using 'dumpimage -l'.
This uses the 'dtbs-list' file but processes only .dtb files, ignoring
the overlay .dtbo files.
This features requires pylibfdt (use 'pip install libfdt'). It also
requires compression utilities for the algorithm being used. Supported
compression options are the same as the Image.xxx files. Use
FIT_COMPRESSION to select an algorithm other than gzip.
While FIT supports a ramdisk / initrd, no attempt is made to support
this here, since it must be built separately from the Linux build.

Add driver for MediaTek's XFI T-PHY which can be found in the MT7988
SoC. The XFI T-PHY is a 10 Gigabit/s Ethernet SerDes PHY with muxes on
the internal side to be used with either USXGMII PCS or LynxI PCS,
depending on the selected PHY interface mode.
The PHY can operates only in PHY_MODE_ETHERNET, the submode is one of
PHY_INTERFACE_MODE_* corresponding to the supported modes:
* USXGMII \
* 10GBase-R }- USXGMII PCS - XGDM \
* 5GBase-R / \
}- Ethernet MAC
* 2500Base-X \ /
* 1000Base-X }- LynxI PCS - GDM /
* Cisco SGMII (MAC side) /
I chose the name XFI T-PHY because names of functions dealing with the
phy in the vendor driver are prefixed "xfi_pextp_".
The register space used by the phy is called "pextp" in the vendor
sources, which could be read as "_P_CI _ex_press _T_-_P_hy", and that
is quite misleading as this phy isn't used for anything related to
PCIe, so I wanted to find a better name.
XFI is still somehow related (as in: you would find the relevant
places using grep in the vendor driver when looking for that) and the
term seemed to at least somehow be aligned with the function of that
phy: Dealing with (up to) 10 Gbit/s Ethernet serialized differential
signals.
In order to work-around a performance issue present on the first of
two XFI T-PHYs found in MT7988, special tuning is applied which can
be selected by adding the 'mediatek,usxgmii-performance-errata'
property to the device tree node, similar to how the vendor driver is
doing that too.
There is no documentation for most registers used for the
analog/tuning part, however, most of the registers have been partially
reverse-engineered from MediaTek's SDK implementation (see links, an
opaque sequence of 32-bit register writes) and descriptions for all
relevant digital registers and bits such as resets and muxes have been
supplied by MediaTek.

Add support for Tegra Security Engine which can accelerate various
crypto algorithms. The Engine has two separate instances within for
AES and HASH algorithms respectively.
The driver registers two crypto engines - one for AES and another for
HASH algorithms and these operate independently and both uses the host1x
bus. Additionally, it provides hardware-assisted key protection for up
to 15 symmetric keys which it can use for the cipher operations.

Notable user impacting bugs
- On multi device filesystems, recovery was looping in
btree_trans_too_many_iters(). This checks if a transaction has touched
too many btree paths (because of iteration over many keys), and isuses
a restart to drop unneeded paths. But it's now possible for some paths
to exceed the previous limit without iteration in the interior btree
update path, since the transaction commit will do alloc updates for
every old and new btree node, and during journal replay we don't use
the btree write buffer for locking reasons and thus those updates use
btree paths when they wouldn't normally.
- Fix a corner case in rebalance when moving extents on a durability=0
device. This wouldn't be hit when a device was formatted with
durability=0 since in that case we'll only use it as a write through
cache (only cached extents will live on it), but durability can now be
changed on an existing device.
- bch2_get_acl() could rarely forget to handle a transaction restart;
this manifested as the occasional missing acl that came back after
dropping caches.
- Fix a major performance regression on high iops multithreaded write
workloads (only since 6.9-rc1); a previous fix for a deadlock in the
interior btree update path to check the journal watermark introduced a
dependency on the state of btree write buffer flushing that we didn't
want.
- Assorted other repair paths and recovery fixes.

Fedora and openSUSE has started deploying "variable font" [1] format
Noto CJK fonts [2, 3]. "CJK" here stands for "Chinese, Japanese,
and Korean".
Unfortunately, XeTeX/XeLaTeX doesn't understand those fonts for
historical reasons and builds of translations.pdf end up in errors
if such fonts are present on the build host.
To help developers work around the issue, add a script to check the
presence of "variable font" Noto CJK fonts and to emit suggestions.
The script is invoked in the error path of "make pdfdocs" so that the
suggestions are made only when a PDF build actually fails.
The first suggestion is to denylist those "variable font" files by
activating a per-user and command-local fontconfig setting.
For further info and backgrounds, please refer to the header comment
of scripts/check-variable-font.sh newly added in this commit.

This drivers supports the ACPI quickstart button device, which
is used to send manufacturer-specific events to userspace.
Since the meaning of those events is not standardized, userspace
has to use for example hwdb to decode them.
The driver itself is based on an earlier proposal, but contains
some improvements and uses the device wakeup API instead of a

Link topologies containing multiple network PHYs attached to the same
net_device can be found when using a PHY as a media converter for use
with an SFP connector, on which an SFP transceiver containing a PHY can
be used.
With the current model, the transceiver's PHY can't be used for
operations such as cable testing, timestamping, macsec offload, etc.
The reason being that most of the logic for these configuration, coming
from either ethtool netlink or ioctls tend to use netdev->phydev, which
in multi-phy systems will reference the PHY closest to the MAC.
Introduce a numbering scheme allowing to enumerate PHY devices that
belong to any netdev, which can in turn allow userspace to take more
precise decisions with regard to each PHY's configuration.
The numbering is maintained per-netdev, in a phy_device_list.
The numbering works similarly to a netdevice's ifindex, with
identifiers that are only recycled once INT_MAX has been reached.
This prevents races that could occur between PHY listing and SFP
transceiver removal/insertion.
The identifiers are assigned at phy_attach time, as the numbering
depends on the netdevice the phy is attached to. The PHY index can be
re-used for PHYs that are persistent.

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:
Set of changes targeting the avs-driver only. No new features, patchset
either fixes or fortifies existing code.
Patchset starts off with a fix for debugbility on ICL+ platforms which I
have forgotten to fixup when providing support for these initially.
The next two address copier module initialization, most importantly,
silence the gcc 'field-spanning write' false-positive.
The following four:
6/13 ASoC: Intel: avs: Replace risky functions with safer variants
7/13 ASoC: Intel: avs: Fix potential integer overflow
8/13 ASoC: Intel: avs: Test result of avs_get_module_entry()
9/13 ASoC: Intel: avs: Remove dead code
address problems found out by Coverity static analysis tool.
The last two worth mentioning are: recommendation from the firmware team
to wake subsystem from D0ix when starting any pipeline -and- shielding
against invalid period/buffer sizes. Audio format shall be taken into
consideration when calculating either of these.
Amadeusz Sławiński (2):
ASoC: Intel: avs: Restore stream decoupling on prepare
ASoC: Intel: avs: Add assert_static to guarantee ABI sizes
Cezary Rojewski (11):
ASoC: Intel: avs: Fix debug-slot offset calculation
ASoC: Intel: avs: Silence false-positive memcpy() warnings
ASoC: Intel: avs: Fix config_length for config-less copiers

There are a couple of fixups for this cycle's vmalloc changes and one for
the stackdepot changes. And a fix for a very old x86 PAT issue which can
cause a warning splat.
