Devicetree updates for v5.9:

- Improve device links cycle detection and breaking.  Add more
  bindings for device link dependencies.

- Refactor parsing 'no-map' in __reserved_mem_alloc_size()

- Improve DT unittest 'ranges' and 'dma-ranges' test case to check
  differing cell sizes

- Various http to https link conversions

- Add a schema check to prevent 'syscon' from being used by itself
  without a more specific compatible

- A bunch more DT binding conversions to schema

wireless-drivers-next patches for v5.9

Second set of patches for v5.9. mt76 has most of patches this time.
Otherwise it's just smaller fixes and cleanups to other drivers.

There was a major conflict in mt76 driver between wireless-drivers and
wireless-drivers-next. I solved that by merging the former to the
latter.

Major changes:

rtw88

* add support for ieee80211_ops::change_interface

* add support for enabling and disabling beacon

* add debugfs file for testing h2c

mt76

* ARP filter offload for 7663

* runtime power management for 7663

* testmode support for mfg calibration

* support for more channels

ACPI updates for 5.9-rc1

 - Eliminate significant AML processing overhead related to using
   operation regions in system memory by reworking the management
   of memory mappings in the ACPI code to defer unmap operations
   (to do them outside of the ACPICA locks, among other things) and
   making the memory operation reagion handler avoid releasing memory
   mappings created by it too early (Rafael Wysocki).

 - Update the ACPICA code in the kernel to upstream revision
   20200717:

   * Prevent operation region reference counts from overflowing in
     some cases (Erik Kaneda).

   * Replace one-element array with flexible-array (Gustavo A. R.
     Silva).

 - Fix ACPI PCI hotplug reference counting (Rafael Wysocki).

 - Drop last bits of the ACPI procfs interface (Thomas Renninger).

 - Drop some redundant checks from the code parsing ACPI tables
   related to NUMA (Hanjun Guo).

   handling code (Heikki Krogerus).

   of the ACPI tables recognized by the kernel (Ard Biesheuvel).

   Intel RAPL power capping driver (Sumeet Pawnikar, Zhang Rui).

 - Fix function name in kerneldoc comments in the idle_inject power
   capping driver (Yangtao Li).

 - Fix locking issues with cpufreq governors and drop a redundant
   "weak" function definition from cpufreq (Viresh Kumar).

 - Rearrange cpufreq to register non-modular governors at the
   core_initcall level and allow the default cpufreq governor to
   be specified in the kernel command line (Quentin Perret).

 - Extend, fix and clean up the intel_pstate driver (Srinivas
   Pandruvada, Rafael Wysocki):

   * Add a new sysfs attribute for disabling/enabling CPU
     energy-efficiency optimizations in the processor.

   * Make the driver avoid enabling HWP if EPP is not supported.

   * Allow the driver to handle numeric EPP values in the sysfs
     interface and fix the setting of EPP via sysfs in the active
     mode.

   * Eliminate a static checker warning and clean up a kerneldoc
     comment.

 - Clean up some variable declarations in the powernv cpufreq
   driver (Wei Yongjun).

 - Fix up the ->enter_s2idle callback definition to cover the case
   when it points to the same function as ->idle correctly (Neal
   Liu).

 - Rearrange and clean up the PSCI cpuidle driver (Ulf Hansson).

 - Make the PM core emit "changed" uevent when adding/removing the
   "wakeup" sysfs attribute of devices (Abhishek Pandit-Subedi).

 - Add a helper macro for declaring PM callbacks and use it in the
   MMC jz4740 driver (Paul Cercueil).

 - Fix white space in some places in the hibernate code and make the
   system-wide PM code use "const char *" where appropriate (Xiang
   Chen, Alexey Dobriyan).

     consistently.

   * Add the rockchip,pmu phandle to the rk3399_dmc driver DT
     bindings.

   * List Dmitry Osipenko as the Tegra devfreq driver maintainer.

android-mainline @ v5.8

regulator: Updates for v5.9

This time around the bulk of the work on the regulator API has been
cleanups of various kinds, partly but not entirely inspired by the W=1
stuff that 0day turned on.  There's also been a fairly large crop of new
drivers, and a few bugfixes for existing drivers.

 - Mode setting support for MT6397 and DA9211.
 - New drivers for ChromeOS embedded controllers, Fairchild FAN53880,
   NXP PCA9450, Qualcomm LABIBB, MP5496, and VBUS booster, and Silergy
   SY8827N

ASoC: Updates for v5.9

The biggest changes here one again come from Mormioto-san who has
continued his dilligent work cleaning up long standing issues in the
APIs, it's particularly nice to see the transition from digital_mute()
to mute_stream() finally completed. There's also been a lot of work on
the x86 code again, this time a big focus has been on cleaning up some
issues identified by various static tests, and on the Freescale systems.
Otherwise the biggest thing has been a lot of driver additions:

 - Convert users of digital_mute() to mute_stream().
 - Simplify I/O helper functions.
 - Add a helper for getting the RTD from a substream.
 - Many, many fixes and cleanups to the x86 code.
 - New drivers for Freescale MQS and i.MX6sx, Intel KeemBay I2S, Maxim
   MAX98360A and MAX98373 Soundwire, several Mediatek boards, nVidia
   Tegra 186 and 210, RealTek RL6231, Samsung Midas and Aries boards (some
   of the first phones I worked on!) and TI J721e EVM.

wireless-drivers-next patches for v5.9

Second set of patches for v5.9. These patches have not been build
tested as much as normally because I'm on vacation right now.
Hopefully this does not cause any regressions.

mt76 has most of patches this time. Otherwise it's just smaller fixed
and cleanups to other drivers.

This pull request causes conflicts in four files in
drivers/net/wireless/mediatek/mt76/mt7615/, here is how I fixed those:

* usb.c: take the hunk which uses mt7663_usb_sdio_tx_*() functions

* mt7615.h: remove either one of the duplicate (and identical) enum tx_pkt_queue_idx

* mt7615.h: take the hunk which has mt7615_mutex_acquire/release() functions

* main.c: take the hunk which uses mt7615_mutex_acquire/release()

* mac.c: take the hunk which uses is_mmio

Major changes:

rtw88

* add support for ieee80211_ops::change_interface

* add support for enabling and disabling beacon

* add debugfs file for testing h2c

mt76

* ARP filter offload for 7663

* runtime power management for 7663

* testmode support for mfg calibration

* support for more channels

Qualcomm driver additional updates for 5.9

This fixes a potential race condition with remoteprocs by not sending
acknowledgements until after registered drivers has processed the event.
It adds IPQ6018 support to the SMD RPM driver, fixes kerneldoc in the
same and converts the related DT binding to YAML.
Finally it fixes a compilation warning in the geni serial engine driver
when compiled without CONFIG_SERIAL_EARLYCON.

Qualcomm ARM64 DT additional updates for 5.9

For SC7180 this adds the necessary properties for blowing fuses in
qfprom, Coresight fixes, GPU interconnect votes and specifies max speed
for USB controller.

SM8150 and SM8250 gains Adreno SMMU, the graphics management unit and
the GPU nodes, to enable headless GPU usage.

SDM845 gains tracing support for deep idle, GPU bus bandwidth scaling
and DB845c gains the LT9611 HDMI bridge wired up.

Z5.

MSM8992 is refactored and modernized and gets support for SCM, SPMI,
BLSP2 UART and I2C nodes, PMU, RPM clock controller, PSCI and proper CPU
definitions. Support for the Xiaomi Libra and Microsoft Lumia 950 are
added.
