The ASPEED AST2400/2500 PWM controller supports 8 PWM output ports.
The ASPEED AST2400/2500 Fan tach controller supports 16 tachometer
inputs.
The device driver matches on the device tree node. The configuration
values are read from the device tree and written to the respective
registers.
The driver provides a sysfs entries through which the user can
configure the duty-cycle value (ranging from 0 to 100 percent) and read
the fan tach rpm value.

Introduce the "lrclk-strength" property to allow LRCLK pad drive strength
to be changed via device tree.
When running a stress playback loop test on a mx6dl wandboard channel
swap can be noticed on about 10% of the times.
While debugging this issue I noticed that when probing the SGTL5000
LRCLK pin with the scope the swap did not happen. After removing
the probe the swap started to happen again.
After changing the LRCLK pad drive strength to the maximum value the
issue is gone.
Same fix works on a mx6dl Colibri board as well.

The resource control filesystem provides only a bitmask based cpus file for
assigning CPUs to a resource group. That's cumbersome with large cpumasks
and non-intuitive when modifying the file from the command line.
Range based cpu lists are commonly used along with bitmask based cpu files
in various subsystems throughout the kernel.
Add 'cpus_list' file which is CPU range based.
# cd /sys/fs/resctrl/
# echo 1-10 > krava/cpus_list
# cat krava/cpus_list
1-10
# cat krava/cpus
0007fe
# cat cpus

# cat cpus_list

Update extcon for 4.12
Detailed description for this pull request:
1. Add new 'extcon-intel-cht-wc.c' driver
- Intel Cherrytrail Whiskey Cove PMIC extcon driver supports
the detection of the charger connectors and the control.
2. Add new extcon API to monitor the all external connectors.
- The extcon consumer might need to monitor the all supported external
connectors from the extcon device. Before, the extcon consumer
should have each notifier_block structure for each external connector.
In order to support the requirement, the extcon adds new
extcon_register_notifier_all() API. The extcon consumer is able
to monitor the state change of all supported external connectors
from the extcon device by using only one notifier_block.
- extcon_(register|unregister)_notifier_all(struct extcon_dev *edev
struct notifier_block *nb)
- devm_extcon_(register|unregister)_notifier_all(struct device *dev,
struct extcon_dev *edev
struct notifier_block *nb)
3. Remove porting compatibility of old switch class
- The extcon removes the porting compatibility of old switch class
because there are no any use-case and requirement of switch class.
4. Update the extcon drivers and Fix the minor issues
- Revert the ACPI gpio interface on the extcon-usb-gpioc.c.
- Fix the issues related to the suspend-to-ram for both extcon-usb-gpio.c
and extcon-palmas.c.
- Add warning message for extcon-arizona.c when headphone detection is not
finished.

The documentation for video capture and output devices claims that the video standard
ioctls are required. This is not the case, they are only required for PAL/NTSC/SECAM
type inputs and outputs. Sensors do not implement this at all and e.g. HDMI inputs
implement the DV Timings ioctls.
Just drop the mention of 'video standard' ioctls.

We have 2 modes for dealing with interrupts in the ARM world. We can
either handle them all using hardware acceleration through the vgic or
we can emulate a gic in user space and only drive CPU IRQ pins from
there.
Unfortunately, when driving IRQs from user space, we never tell user
space about events from devices emulated inside the kernel, which may
result in interrupt line state changes, so we lose out on for example
timer and PMU events if we run with user space gic emulation.
Define an ABI to publish such device output levels to userspace.

In order to accommodate in a logical manner for the premuxed channels
in PM8921 and the similarly addressed channels in later PMICs, we
need a twocell arrangement with premux and analog mux setting as
a tuple to uniquely identify a hardware channel.
These bindings are not yet in use, so it should be fine to augment
them before we actually start using it in drivers and device trees.
This scheme came out of lengthy discussions and reverse-engineering
and reading of the few information sources we have.

This patch adds documentation describing a device tree binding for the
coreboot firmware. It is meant to be dynamically added during boot and
contains address definitions for the coreboot table (a list of
variable-sized descriptors providing information about various compile-
and run-time generated firmware parameters) and the CBMEM area (the
structure containing most run-time resident memory regions set up by
coreboot).
These definitions allow kernel drivers to easily access data contained
in and pointed to by these regions (such as coreboot's in-memory log).
