Pull power management updates from Rafael Wysocki:
"The majority of changes go into the Operating Performance Points (OPP)
framework and cpufreq this time, followed by devfreq and some
scattered updates all over.
The OPP changes are mostly related to switching over from RCU-based
synchronization, that turned out to be overly complicated and
problematic, to reference counting using krefs.
In the cpufreq land there are core cleanups, documentation updates, a
new driver for Broadcom BMIPS SoCs, a new cpufreq-dt sub-driver for TI
SoCs that require special handling, ARM64 SoCs support for the qoriq
driver, intel_pstate updates, powernv driver update and assorted
fixes.
The devfreq changes are mostly fixes related to the sysfs interface
and some Exynos drivers updates.
Apart from that, the cpuidle menu governor will support per-CPU PM QoS
constraints for the wakeup latency now, some bugs in the wakeup IRQs
framework are fixed, the generic power domains framework should handle
asynchronous invocations of *noirq suspend/resume callbacks from now
on, the analyze_suspend.py script is updated and there is a new tool
for intel_pstate diagnostics.
Specifics:
- Operating Performance Points (OPP) framework fixes, cleanups and
switch over from RCU-based synchronization to reference counting
using krefs (Viresh Kumar, Wei Yongjun, Dave Gerlach)
- cpufreq core cleanups and documentation updates (Viresh Kumar,

like in the AM335x, AM437x, DRA7x, and AM57x families, along with
new DT bindings for it (Dave Gerlach, Paul Gortmaker)
- ARM64 SoCs support for the qoriq cpufreq driver (Tang Yuantian)
- intel_pstate driver updates including a new sysfs knob to control
the driver's operation mode and fixes related to the no_turbo sysfs
knob and the hardware-managed P-states feature support (Rafael
Wysocki, Srinivas Pandruvada)
- New interface to export ultra-turbo frequencies for the powernv
cpufreq driver (Shilpasri Bhat)
- Assorted fixes for cpufreq drivers (Arnd Bergmann, Dan Carpenter,
Wei Yongjun)
- devfreq core fixes, mostly related to the sysfs interface exported
by it (Chanwoo Choi, Chris Diamand)
- Updates of the exynos-bus and exynos-ppmu devfreq drivers (Chanwoo
Choi)
- Device PM QoS extension to support CPUs and support for per-CPU
wakeup (device resume) latency constraints in the cpuidle menu
governor (Alex Shi)
- Wakeup IRQs framework fixes (Grygorii Strashko)
- Generic power domains framework update including a fix to make it
handle asynchronous invocations of *noirq suspend/resume callbacks
correctly (Ulf Hansson, Geert Uytterhoeven)
- Assorted fixes and cleanups in the core suspend/hibernate code, PM
QoS framework and x86 ACPI idle support code (Corentin Labbe, Geert
Uytterhoeven, Geliang Tang, John Keeping, Nick Desaulniers)

offering multiple improvements (Todd Brandt)

Pull LED updates from Jacek Anaszewski:
"New features and improvements:
- add new optional brightness_hw_changed attribute for the LEDs that
may have their brightness level changed autonomously (outside of
kernel control) by hardware / firmware. The attribute supports
userspace notifications through POLLPRI events
- add led_brightness_hw_mon tool that demonstrates how to use the
aforementioned feature
- add LED_ON enum for LEDs that can be only turned on/off, and don't
allow setting other brightness levels
- allow for adjusting heartbeat trigger blink brightness level
Fixes and cleanups:
- avoid harmless maybe-uninitialized warning in leds-ktd2692.c
- add context to the existing example entries in common LED bindings
to make the documentation more clear"

This driver supports the Lantiq SSC SPI controller in master
mode. This controller is found on Intel (former Lantiq) SoCs like
the Danube, Falcon, xRX200, xRX300.
The hardware uses two hardware FIFOs one for received and one for
transferred bytes. When the driver writes data into the transmit FIFO
the complete word is taken from the FIFO into a shift register. The
data from this shift register is then written to the wire. This driver
uses the interrupts signaling the status of the FIFOs and not the shift
register. It is also possible to use the interrupts for the shift
register, but they will send a signal after every word. When using the
interrupts for the shift register we get a signal when the last word is
written into the shift register and not when it is written to the wire.
After all FIFOs are empty the driver busy waits till the hardware is
not busy any more and returns the transfer status.

|

This reverts 'commit 7e0739cd9c40 ("[media] videodev2.h: fix
sYCC/AdobeYCC default quantization range").
The problem is that many drivers can convert R'G'B' content (often
from sensors) to Y'CbCr, but they all produce limited range Y'CbCr.
To stay backwards compatible the default quantization range for
sRGB and AdobeRGB Y'CbCr encoding should be limited range, not full
range, even though the corresponding standards specify full range.
Update the V4L2_MAP_QUANTIZATION_DEFAULT define accordingly and
also update the documentation.

Add the device tree bindings document for the TI CPUFreq/OPP driver
on AM33xx, AM43xx, DRA7xx, and AM57xx SoCs. The operating-points-v2
binding allows us to provide an opp-supported-hw property for each OPP
to define when it is available. This driver is responsible for reading
and parsing registers to determine which OPPs can be selectively enabled
based on the specific SoC in use by matching against the opp-supported-hw
data.

erratum
This erratum describes a bug in logic outside the core, so MIDR can't be
