This patch adds a simple device driver to expose the iBT interface on
Aspeed SOCs (AST2400 and AST2500) as a character device. Such SOCs are
commonly used as BMCs (BaseBoard Management Controllers) and this
driver implements the BMC side of the BT interface.
The BT (Block Transfer) interface is used to perform in-band IPMI
communication between a host and its BMC. Entire messages are buffered
before sending a notification to the other end, host or BMC, that
there is data to be read. Usually, the host emits requests and the BMC
responses but the specification provides a mean for the BMC to send
SMS Attention (BMC-to-Host attention or System Management Software
attention) messages.
For this purpose, the driver introduces a specific ioctl on the
device: 'BT_BMC_IOCTL_SMS_ATN' that can be used by the system running
on the BMC to signal the host of such an event.
The device name defaults to '/dev/ipmi-bt-host'

If userspace creates a PMU for the VCPU, but doesn't create an in-kernel
irqchip, then we end up in a nasty path where we try to take an
uninitialized spinlock, which can lead to all sorts of breakages.
Luckily, QEMU always creates the VGIC before the PMU, so we can
establish this as ABI and check for the VGIC in the PMU init stage.
This can be relaxed at a later time if we want to support PMU with a
userspace irqchip.

This commit adds a new trigger responsible for turning on LED when USB
device gets connected to the selected USB port. This can can useful for
various home routers that have USB port(s) and a proper LED telling user
a device is connected.
The trigger gets its documentation file but basically it just requires
enabling it and selecting USB ports (e.g. echo 1 > ports/usb1-1).
There was a long discussion on design of this driver. Its current state
is a result of picking them most adjustable solution as others couldn't
handle all cases.
1) It wasn't possible for the driver to register separated trigger for
each USB port. Some physical USB ports are handled by more than one
controller and so by more than one USB port. E.g. USB 2.0 physical
port may be handled by OHCI's port and EHCI's port.
It's also not possible to assign more than 1 trigger to a single LED
and implementing such feature would be tricky due to syncing triggers
and sysfs conflicts with old triggers.
2) Another idea was to register trigger per USB hub. This wouldn't allow
handling devices with multiple USB LEDs and controllers (hubs)
controlling more than 1 physical port. It's common for hubs to have
few ports and each may have its own LED.
This final trigger is highly flexible. It allows selecting any USB ports
for any LED. It was also modified (comparing to the initial version) to
allow choosing ports rather than having user /guess/ proper names. It
was successfully tested on SmartRG SR400ac which has 3 USB LEDs,
2 physical ports and 3 controllers.
It was noted USB subsystem already has usb-gadget and usb-host triggers
but they are pretty trivial ones. They indicate activity only and can't
have ports specified.
In future it may be good idea to consider adding activity support to
usbport as well. This should allow switching to this more generic driver
and maybe marking old ones as obsolete.
This can be implemented with another sysfs file for setting mode. The
default mode wouldn't change so there won't be ABI breakage and so such
feature can be safely implemented later.
There was also an idea of supporting other devices (PCI, SDIO, etc.) but
as this driver already contains some USB specific code (and will get
more) these should be probably separated drivers (triggers).

This adds support for hardware-tracked trip points to the device tree
thermal sensor framework.
The framework supports an arbitrary number of trip points. Whenever
the current temperature is updated, the trip points immediately
below and above the current temperature are found. A .set_trips
callback is then called with the temperatures. If there is no trip
point above or below the current temperature, the passed trip
temperature will be -INT_MAX or INT_MAX respectively. In this callback,
the driver should program the hardware such that it is notified
when either of these trip points are triggered. When a trip point
is triggered, the driver should call `thermal_zone_device_update'
for the respective thermal zone. This will cause the trip points
to be updated again.
If .set_trips is not implemented, the framework behaves as before.
This patch is based on an earlier version from Mikko Perttunen

On some boards (android tablets) different batches use different sdio
wifi modules. This is not a problem since mmc/sdio is an enumerable bus,
so we only need to describe and activate the mmc controller in dt and
then the kernel will automatically load the right driver.
Sometimes it is useful to specify certain ethernet properties for these
"unknown" sdio devices, specifically we want the boot-loader to be able
to set "local-mac-address" as some of these sdio wifi modules come without
an eeprom / without a factory programmed mac address.
Since the exact device is unknown (differs per batch) we cannot use
a wifi-chip specific compatible, thus sometimes it is desirable to have a
mmc function node, without having to make up an otherwise unused compatible
for the node, so make the compatible property optional.

Since sun4i / sun5i do not have sample clocks, they cannot (reliably) do

Note this patch leaves the clk_prepare_enable() / clk_disable_unprepare()

tlv320dac31xx is a subset of tlv320aic31xx:
- it does not have MIC inputs and ADC, thus capture is not supported,
- it has analog inputs AIN1/AIN2 that can be mixed into output.
Although tlv320dac31xx does work with tlv320aic31xx driver, this setup
does register non-existent widgets and non-existent capture stream.
Thus userspace lists non-existent objects in user interfaces, an can
access these, causing operations with device registers that are
declared as "reserved" in tlv320dac31xx datasheet.
This patch fixes this situation by separating controls/widgets/routes
into common, aic31xx-specific, and dac31xx-specific parts. Only parts
that match actual hardware (as declared in "compatible" device tree
property) are registered.

Erratum A-008585 says that the ARM generic timer counter "has the
potential to contain an erroneous value for a small number of core
clock cycles every time the timer value changes". Accesses to TVAL
(both read and write) are also affected due to the implicit counter
read. Accesses to CVAL are not affected.
The workaround is to reread TVAL and count registers until successive
reads return the same value. Writes to TVAL are replaced with an
equivalent write to CVAL.
The workaround is to reread TVAL and count registers until successive reads
return the same value, and when writing TVAL to retry until counter
reads before and after the write return the same value.
The workaround is enabled if the fsl,erratum-a008585 property is found in
the timer node in the device tree. This can be overridden with the
clocksource.arm_arch_timer.fsl-a008585 boot parameter, which allows KVM
users to enable the workaround until a mechanism is implemented to
automatically communicate this information.
This erratum can be found on LS1043A and LS2080A.

When using GPIO irqchip helpers to setup irqchip for a gpiolib based
driver, it is not possible to select which GPIOs to add to the IRQ domain.
Instead it just adds all GPIOs which is not always desired. For example
there might be GPIOs that for some reason cannot generated normal
interrupts at all.
To support this we add a flag irq_need_valid_mask to struct gpio_chip. When
this flag is set the core allocates irq_valid_mask that holds one bit for
each GPIO the chip has. By default all bits are set but drivers can
manipulate this using set_bit() and clear_bit() accordingly.
Then when gpiochip_irqchip_add() is called, this mask is checked and all
GPIOs with bit is set are added to the IRQ domain created for the GPIO
chip.

The generic NAND DT bindings allows one to tweak the ECC strength and
step size to their need. It can be used to lower the ECC strength to
match a bootloader/firmware config, but might also be used to get a better
reliability.
In the latter case, the user might want to use the maximum ECC strength
without having to explicitly calculate the exact value (this value not
only depends on the OOB size, but also on the NAND controller, and can
be tricky to extract).
Add a generic 'nand-ecc-maximize' DT property and the associated
NAND_ECC_MAXIMIZE flag, to let ECC controller drivers select the best
ECC strength and step-size on their own.

Background/Reasoning:
Books:
------
* Linux Kernel Networking by Rami Rosen
While some parts are quite short and could be
more carefully explained it's still a good recomendation
for understanding linux kernel networking, (IMHO)
* Linux Treiber entwickeln:
It sure is a drawback that this is a german book.
But it's quite recent, well structured and there are also
other non-english (spanish) books/papers in this list.
Papers:
-------
* On Submitting kernel Patches
Contains 2 case studies of bigger patch sets and how (or how not)
they were merged. I found it helpful
* Tracing the Way of Data in a TCP Connection through the Linux Kernel
Since this was written by me this inclusion may be a bit biased :p
Neitherless I think this gives a good introduction on
understanding/exploring linux internals using ftrace and an overview
of Linux TCP internals.

On Sphinx/ReST notation, ``foo`` means that foo will be will be
marked as inline literal, effectively making it to be presented
as a monospaced font.
As we want this document to be parsed by Sphinx, instead of using
"foo", use ``foo`` for the names that are literal, because it is an
usual typographic convention to use monospaced fonts for functions
and language commands on documents, and we're following such
convention on the other ReST books.

As discussed at linux-doc ML, the best is to keep all documents
backward compatible with Sphinx version 1.2, as it is the latest
version found on some distros like Debian.
All books currently support it.
Please notice that, while it mentions the eventual need of
XeLaTex and texlive to build pdf files, this is not a minimal
requirement, as one could just be interested on building html
documents. Also, identifying the minimal requirements for
texlive packages is not trivial, as each distribution seems to
use different criteria on grouping LaTex functionalities.

Suggested patch solves two issues:
1) Currently documentation is unclear whether `make kselftest` should
be run before or after kernel was installed and booted. `make help`
gives a clear answer on that: "kselftest - Build and run kernel selftest
(run as root). Build, install, and boot kernel before running kselftest
on it."
2) Documentation states that `make kselftest` executes "unit" tests.
Technically it's not a _unit_ test if it requires to install an
application first. It's either integration or system test. To not to
confuse a user I suggest not to use a word "unit".

In a typical IPvlan L3 setup where master is in default-ns and
each slave is into different (slave) ns. In this setup egress
packet processing for traffic originating from slave-ns will
hit all NF_HOOKs in slave-ns as well as default-ns. However same
is not true for ingress processing. All these NF_HOOKs are
hit only in the slave-ns skipping them in the default-ns.
IPvlan in L3 mode is restrictive and if admins want to deploy
iptables rules in default-ns, this asymmetric data path makes it
impossible to do so.
This patch makes use of the l3_rcv() (added as part of l3mdev
enhancements) to perform input route lookup on RX packets without
changing the skb->dev and then uses nf_hook at NF_INET_LOCAL_IN
to change the skb->dev just before handing over skb to L4.

This short series convers device-drivers.tmpl into the RST format, splits
it up, and sets up the result under Documentation/driver-api/. For added
fun, I've taken one top-level file (hsi.txt) and folded it into the
document as a way of showing the direction I'm thinking I would like things
to go. There is plenty more of this sort of work that could be done, to
say the least - this is just a beginning!
The formatted results can be seen at:
http://static.lwn.net/kerneldoc/driver-api/index.html
As part of the long-term task to turn Documentation/ into less of a horror
movie, I'd like to collect documentation of the driver-specific API here.
Arguably gpu/ and the media API stuff should eventually move here, though
we can discuss the color of that particular shed some other day.
Meanwhile, I'd appreciate comments on the general idea.

The existing IOMMU bindings are able to specify the relationship between
masters and IOMMUs, but they are insufficient for describing the general
case of hotpluggable busses such as PCI where the set of masters is not
known until runtime, and the relationship between masters and IOMMUs is
a property of the integration of the system.
This patch adds a generic binding for mapping PCI devices to IOMMUs,
using a new iommu-map property (specific to PCI*) which may be used to
map devices (identified by their Requester ID) to sideband data for the
IOMMU which they master through.

Make the following changes in the HDMI gpio bindings:
- Use "-gpios" as the suffix for all the gpio names
- Move all the gpios to optional, since there are platforms that use none
of them.
- The HPD gpio is a standard one, remove the "qcom,hdmi-tx-" prefix from
it.
- Remove the HDMI DDC clk/data gpios. They are just leftovers of an old
way to configure pinctrl properties.
- Add a missing lpm gpio used on some platforms.
Make the necessary changes in the driver to incorporate these changes.
There hasn't been any upstream DT that uses the HDMI bindings, so it's
okay to change and move around these properties.

"msb7800", "msn2740", "msn2100".
Driver obtains LED devices according to system configuration, provided
through system DMI data, like mlxcpld:fan1:green, mlxcpld:fan1:red and
creates devices in form: "devicename:colour:function".
LED setting is controlled through on board CPLD Lattice device.
For setting particular LED off, solid, blink:
echo 0 > /sys/class/leds/mlxcpld\:status\:green/brightness
echo 1 > /sys/class/leds/mlxcpld\:status\:green/brightness
echo timer > /sys/class/leds/mlxcpld\:status\:green/trigger
On module probing all LEDs are set green, on removing - off.
Last setting overwrites previous, f.e. sequence for
changing LED from green - red - green:
echo 1 > /sys/class/leds/mlxcpld\:psu\:green/brightness
echo 1 > /sys/class/leds/mlxcpld\:psu\:red/brightness
echo 1 > /sys/class/leds/mlxcpld\:psu\:green/brightness

Per the PCI Firmware spec, r3.0, sec 4.5.1, on ACPI systems, the OS must
not use AER unless _OSC is present and _OSC grants AER control to the OS.
The aerdriver.forceload kernel parameter was a way to enable Linux AER
support on ACPI systems that lack _OSC or fail to grant control the the OS.
Enabling Linux AER support when the firmware doesn't want us to is a recipe
for problems, e.g., the firmware might be handling AER itself.
Remove the aerdriver.forceload kernel parameter and related supporting
code.

The aerdriver.nosourceid kernel parameter was intended for working around
broken chipsets don't supply the source ID for AER events. We recently
added PCI_BUS_FLAGS_NO_AERSID, which can be set by quirks for the same
purpose.
Remove the aerdriver.nosourceid kernel parameter. For anything other than
debugging, asking users to find and use kernel parameters is a poor user
experience. Instead, we should add PCI_BUS_FLAGS_NO_AERSID quirks for any
hardware that needs it.

Merge the first drop of irqchip updates for 4.9 from Marc Zyngier:
- ACPI IORT core code
- IORT support for the GICv3 ITS
- A few of GIC cleanups
New device support
* ad8801 dac
- new driver supporting ad8801 and ad8803 DACs.
* adc12138
- new driver supporting TI adc12130/adc12132 and adc12138 ADCs.
* ltc2485 adc
- new driver
* mxc6255
- add support for the mxc6225 part name and fixup the ID check so it works.
* vz89x VOC sensor
- add support for the vz89te part which drops the voc_short channel and adds
CRCs compared to other supported parts.
New features
* core
- immutable triggers. These effectively grant exclusive control over a
trigger. The typical usecase is a device representing an analog part
(perhaps a MUX) that needs to control the sampling of a downstream
ADC.
- resource managed trigger registration and triggered_buffer_init.
- iio_push_event now protected against case of the event interface
registration not having yet occured. Only matters if an interrupt
can occur during this window - might happen on shared interrupt lines.
- helper to let a driver query if the trigger it is using is provided by
itself (using the convention of both device and trigger having the same
parent).
* tools
- iio-utils. Used channel modifier scaling in preference to generic scaling
when both exist.
* at91-adc
- Add support for touchscreen switches closure time needed by some newer
parts.
* stx104
- support the ADC channels on this ADC/DAC board. As these are the primary
feature of the board also move the driver to the iio/adc directory.
* sx9500
- device tree bindings.
Cleanups / Fixes
* ad5755
- fix an off-by-one on devnr limit check (introduced earlier this cycle)
* ad7266
- drop NULL check on devm_regulator_get_optional as it can't return NULL.
* ak8974
- avoid an unused functional warning due to rework in PM core code.
- remove .owner field setting as done by i2c_core.
* ina2xx
- clear out a left over debug field from chip global data.
* hid-sensors
- avoid an unused functional warning due to rework in PM core code.
* maxim-thermocouple
- fix non static symbol warnings.
* ms5611
- fetch and enable regulators unconditionally when they aren't optional.
* sca3000
- whitespace cleanup.
* st_sensors
- fetch and enable regulators unconditionally rather than having them
supported as optional regulators (missunderstanding on my part amongst
others a while back)
- followup to previous patch fixes error checking on the regulators.
- mark symbols static where possible.
- use the 'is it my trigger' help function. This prevents the odd case
of another device triggering from the st-sensors trigger whilst the
st-sensors trigger is itself not using it but rather using say an hrtimer.
* ti-ads1015
- add missing of_node_put.
* vz89x
- rework to all support of new devices.
- prevent reading of a corrupted buffer.
- fixup a return value of 0/1 in a bool returning function.

This time around we have 92 non-merge commits. Most

with drivers/usb/gadget/function being the most
active directory (27.2%).
As for UDC drivers, only dwc3 (26.5%) and dwc2
(12.7%) have really been active.
The most important changes for dwc3 are better
support for scatterlist and, again, throughput
improvements. While on dwc2 got some minor stability
fixes related to soft reset and FIFO usage.
Felipe Tonello has done some good work fixing up our
f_midi gadget and Tal Shorer has implemented a nice
API change for our ULPI bus.
Apart from these, we have our usual set of
non-critical fixes, spelling fixes, build warning
fixes, etc.
