Merge series from Trevor Wu <trevor.wu@mediatek.com>:
This series of patches adds support for memory-region assignment, so the
access region of DMA engine could be restricted.
Patches are based on broonie tree "for-next" branch.

ASoC: Fixes for v5.16
A relatively large collection of updates, the size is increased quite a
bit by there being some repetitive changes for similar issues that occur
multiple times with both notifying control value changes and runtime PM.
The Rockchip update looks at first glance like a cleanup but fixes
instantiation of the hardware on some systems.
i.Core STM32MP1 is an EDIMM SoM based on STM32MP157A from Engicam.
C.TOUCH 2.0 is a general purpose carrier board with capacitive
touch interface support.
10.1" OF is a capacitive touch 10.1" Open Frame panel solutions.
i.Core STM32MP1 needs to mount on top of C.TOUCH 2.0 carrier with
pluged 10.1" OF for creating complete i.Core STM32MP1 C.TOUCH 2.0
10.1" Open Frame board.
Add bindings for it.

Add the dt binding for i.MX8ULP EVK board.
i.MX 8ULP is part of the ULP family with emphasis on extreme
low-power techniques using the 28 nm fully depleted silicon on
insulator process. Like i.MX 7ULP, i.MX 8ULP continues to be
based on asymmetric architecture, however will add a third DSP
domain for advanced voice/audio capability and a Graphics domain
where it is possible to access graphics resources from the
application side or the realtime side.

The TQ-Systems MBa6x mainboard can be used with TQMa6 variants with
i.MX6Q/QP/DL SoCs (TQMa6Q/QP/DL). The TQMa6Q and DL exist in two variants:
The newer variants "A" have a hardware workaround for Erratum ERR006687,
while variants "B" are missing such a workaround, so it needs to be
handled in software. The erratum was fixed in i.MX6QP, so no "A" variant
of the TQMa6QP exists.

pinctrl: renesas: Updates for v5.17
- Add generic support for output impedance,
- Add drive strength and output impedance support for the RZ/G2L SoC,
- Miscellaneous fixes and improvements.
Pull power management fixes from Rafael Wysocki:
"These fix a CPU hot-add issue in the cpufreq core, fix a comment in
the cpufreq core code and update its documentation, and disable the
DTPM (Dynamic Thermal Power Management) code for the time being to
prevent it from causing issues to appear.
Specifics:
- Disable DTPM for this cycle to prevent it from causing issues to
appear on otherwise functional systems (Daniel Lezcano)
- Fix cpufreq sysfs interface failure related to physical CPU hot-add
(Xiongfeng Wang)
- Fix comment in cpufreq core and update its documentation (Tang
Yizhou)"

Pull arm64 fixes from Will Deacon:
"Three arm64 fixes for -rc4.
One of them is just a trivial documentation fix, whereas the other two
address a warning in the kexec code and a crash in ftrace on systems
implementing BTI.
The latter patch has a couple of ugly ifdefs which Mark plans to clean
up separately, but as-is the patch is straightforward for backporting
to stable kernels.
Summary:
- Add missing BTI landing instructions to the ftrace*_caller
trampolines
- Fix kexec() WARN when DEBUG_VIRTUAL is enabled
- Fix PAC documentation by removing stale references to compiler
flags"

The if/then schema for 'data-lanes' doesn't work as 'compatible' is at a
different level than 'data-lanes'. To make it work, the if/then schema
would have to be moved to the top level and then whole hierarchy of
nodes down to 'data-lanes' created. I don't think it is worth the
complexity to do that, so let's just drop it.
The error in this schema is masked by a fixup in the tools causing the
'allOf' to get overwritten. Removing the fixup as part of moving to
json-schema draft 2019-09 revealed the issue:
Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.example.dt.yaml: mipi-csi@30750000: ports:port@0:endpoint:data-lanes:0: [1] is too short
From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.yaml
Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.example.dt.yaml: mipi-csi@32e30000: ports:port@0:endpoint:data-lanes:0: [1, 2, 3, 4] is too long
From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.yaml
The if condition was always true because 'compatible' did not exist in
'endpoint' node and a non-existent property is true for json-schema.

The code and documentation are more difficult to maintain when kept
separately. This is further compounded when the standard structure
documentation infrastructure is not used.
Move the documentation into the code, use the standard documentation
infrastructure, add current documented functions, and reference the text
in the rst file.

It was unclear when the auxiliary device objects were to be free'ed by
the parent (registering) driver.
Also there are some patterns like using devm_add_action_or_reset() which
are helpful to mention to those using the interface to ensure they don't
double free or miss freeing the auxiliary devices.

The documentation for creating an auxiliary device is a 3 step not a 2
step process. Specifically the requirements of setting the name, id,
dev.release, and dev.parent fields was not clear as a precursor to the '2
step' process documented.
Clarify by declaring this a 3 step process starting with setting the
fields of struct auxiliary_device correctly.
Also add some sample code and tie the change into the rest of the
documentation.

Provide default defines for the topology_book_[id|cpumask] and
topology_drawer_[id|cpumask] macros just like for each other topology
level.
This way all topology levels are handled in a similar way. Still the
the book and drawer levels are only used on s390, and also the sysfs
attributes are only created on s390. However other architectures may
opt in if wanted.

The cluster_id and cluster_cpus topology sysfs attributes have been
added with commit c5e22feffd ("topology: Represent clusters of CPUs
within a die").
They are currently only used for x86, arm64, and riscv (via generic
arch topology), however they are still present with bogus default
values for all other architectures. Instead of enforcing such new
sysfs attributes to all architectures, make them only optional visible
if an architecture opts in by defining both the topology_cluster_id
and topology_cluster_cpumask attributes.
This is similar to what was done when the book and drawer topology
levels were introduced: avoid useless and therefore confusing sysfs
attributes for architectures which cannot make use of them.
This should not break any existing applications, since this is a
new interface introduced with the v5.16 merge window.

The die_id and die_cpus topology sysfs attributes have been added with
commit 0e344d8c70 ("cpu/topology: Export die_id") and commit
2e4c54dac7 ("topology: Create core_cpus and die_cpus sysfs attributes").
While they are currently only used and useful for x86 they are still
present with bogus default values for all architectures. Instead of
enforcing such new sysfs attributes to all architectures, make them
only optional visible if an architecture opts in by defining both the
topology_die_id and topology_die_cpumask attributes.
This is similar to what was done when the book and drawer topology

attributes for architectures which cannot make use of them.
This should not break any existing applications, since this is a
rather new interface and applications should be able to handle also
older kernel versions without such attributes - besides that they
contain only useful information for x86.
