e4b99d415c Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 
Pull irq updates from Thomas Gleixner:
 "The interrupt department provides:

  Core updates:

   - Better spreading to NUMA nodes in the affinity management

   - Support for more than one set of interrupts to spread out to allow
     separate queues for separate functionality of a single device.

   - Decouple the non queue interrupts from being managed. Those are
     usually general interrupts for error handling etc. and those should
     never be shut down. This also a preparation to utilize the
     spreading mechanism for initial spreading of non-managed interrupts
     later.

   - Make the single CPU target selection in the matrix allocator more
     balanced so interrupts won't accumulate on single CPUs in certain
     situations.

   - A large spell checking patch so we don't end up fixing single typos
     over and over.

  Driver updates:

   - A bunch of new irqchip drivers (RDA8810PL, Madera, imx-irqsteer)

   - Updates for the 8MQ, F1C100s platform drivers

   - A number of SPDX cleanups

   - A workaround for a very broken GICv3 implementation on msm8996
     which sports a botched register set.

   - A platform-msi fix to prevent memory leakage

   - Various cleanups"

d8924c0d76 Device properties framework updates for 4.21-rc1 
- Introduce "software nodes", analogous to the DT and ACPI firmware
    nodes except that they can be created by kernel code, in order to
    complement fwnodes representing real firmware nodes when they are
    incomplete (for example missing device properties) and to supply
    the primary fwnode when the firmware lacks hardware description
    for a device completely, and replace the "property_set" struct
    fwnode_handle type with software nodes (Heikki Krogerus).
 
  - Clean up the just introduced software nodes support and fix a commet
    in the graph-handling code (Colin Ian King, Marco Felsch).

1fbb2dc6f0 This round is dominated by NXP's i.MX clk drivers. We gained support for two or 
three i.MX SoCs in here and that mostly means a lot of driver code and data.
 Beyond that platform, there are some new Mediatek, Amlogic, and Qualcomm clk
 drivers added in here, and then we get to the long tail of driver updates and
 non-critical fixes all around, including code for vendors such as Renesas,
 Rockchip, Nvidia, and Allwinner. Overall, the driver updates look normal.
 
 Beyond the usual driver updates we have an update to make registering OF based
 clk providers a little simpler when they're devices created as a child of a
 device backed by a node in DT. Drivers don't have to jump through hoops to
 unregister the provider upon driver removal anymore because the API does the
 right thing and uses the parent device DT node.
 
 Core:
  - Make devm_of_clk_add_hw_provider() use parent dt node if necessary
  - Various SPDX taggings
  - Mark clk_ops const when possible
 
 New Drivers:
  - NXP i.MX7ULP SoC clock support
  - NXP i.MX8QXP SoC clock support
  - NXP i.MX8MQ SoC clock support
  - NXP QorIQ T1023 SoC support
  - Qualcomm SDM845 audio subsystem clks
  - Qualcomm SDM845 GPU clck controllers
  - Qualcomm QCS404 RPM clk support
  - Mediatek MT7629 SoC clk controllers
  - Allwinner F1c100s SoC clocks
  - Allwinner H6 display engine clocks
  - Amlogic GX video clocks
  - Support for Amlogic meson8b CPU frequency scaling
  - Amlogic Meson8b CPU post-divider clocks
 
 Updates:
  - Proper suspend/resume on VersaClock5
  - Shrink code some with DEFINE_SHOW_ATTRIBUTE()
  - Register fixes for Rockchip rk3188 and rk3328
  - One new critical clock for Rockchip rk3188 and a fixed clock id (double used number)
  - New clock id for Rockchip rk3328
  - Amlogic Meson8/Meson8b video clock support
  - Amlogic got a clk-input helper and used it for the axg-audio clock driver
  - Sigma Delta modulation for the Allwinner A33 audio clocks
  - Support for CPEX (timer) clocks on various Renesas R-Car Gen3 and RZ/G2 SoCs
  - Support for SDHI HS400 clocks on early revisions of Renesas R-Car H3 and M3-W
  - Support for SDHI and USB clocks on Renesas RZ/A2
  - Support for RPC (SPI Multi I/O Bus Controller) clocks on Renesas R-Car V3M
  - Qualcomm MSM8998 GCC driver improvements (resets, drop unused clks, etc.)

0051db8218 spi: Updates for v4.21 
The main thing this release has been a lot of work on the integration
 with SPI NOR flashes, there's been some specific support for a while for
 controller features designed to make them perform better but it's not
 worked out as well as hoped so the interface has been redesigned in a
 way that will hopefully do better - it's already been adopted by a
 number of additional controllers so things are looking good.  Otherwise
 most of the work has been driver specific:
 
  - Support for better integration with NOR flashes from Boris Brezillon
    and Yogesh Narayan Gaur plus usage of it in several drivers.
  - A big cleanup of the Rockchip driver from Emil Renner Berthing.
  - Lots of performance improvements for bcm2835 from Lukas Wunner.
  - Slave mode support for pxa2xx from Lubomir Rintel.
  - Support for Macronix MXIC, Mediatek MT7629 and MT8183, NPCM PSPI,
    and Renesas r8a77470.

d923fd6dc1 pwm: Changes for v4.21-rc1 
Not a lot going on this cycle. There's some more cleanup going on and
 new driver support that was not quite ready in time for v4.21-rc1, but
 here are a few fixes and improvements that are good to go. The Kona PWM
 driver can now be built on the Cygnus architecture and the i.MX driver
 gained support for hardware readback. Some small fixes are provided for
 the clks711x and lpc18xx-sct drivers. Finally, to round things off some
 drivers are switched to SPDX license identifiers.

  quite ready in time for v4.21-rc1, but here are a few fixes and
  improvements that are good to go.

  The Kona PWM driver can now be built on the Cygnus architecture and
  the i.MX driver gained support for hardware readback. Some small fixes
  are provided for the clks711x and lpc18xx-sct drivers.

  Finally, to round things off some drivers are switched to SPDX license
  identifiers"

1e2af254ef Power management updates for 4.21-rc1 
- Add sysadmin documentation for cpuidle (Rafael Wysocki).
 
  - Make it possible to specify a cpuidle governor from kernel
    command line, add new cpuidle state sysfs attributes for
    governor evaluation, and improve the "polling" idle state
    handling (Rafael Wysocki).
 
  - Fix the handling of the "required-opps" DT property in the
    operating performance points (OPP) framework, improve the
    integration of it with the generic power domains (genpd)
    framework, improve the handling of performance states in
    them and clean up the idle states vs performance states
    separation in genpd (Viresh Kumar, Ulf Hansson).
 
  - Add a cpufreq driver called "qcom-hw" for Qualcomm SoCs using
    a hardware engine to control CPU frequency transitions along
    with DT bindings for it (Taniya Das).
 
  - Fix an intel_pstate driver issue related to CPU offline and
    update the documentation of it (Srinivas Pandruvada).

    for device autosuspend to allow the control of it to be more
    precise (Vincent Guittot).
 
  - Disable non-wakeup ACPI GPEs during suspend-to-idle so that they
    don't prevent the system from reaching the target low-power state
    and simplify the suspend-to-idle handling on ACPI platforms
    without full Low-Power S0 Idle (LPS0) support (Rafael Wysocki).
 
  - Add system-wide suspend and resume support to the devfreq
    framework (Lukasz Luba).

8e61e7b5c4 sound updates for 4.21 
There are no intensive changes in both ALSA and ASoC core parts while
 rather most of changes are a bunch of driver fixes and updates.
 A large diff pattern appears in ASoC TI part which now merges both
 OMAP and DaVinci stuff, but the rest spreads allover the places.
 
 Note that this pull request includes also some updates for LED trigger
 and platform drivers for mute LEDs, appearing in the diffstat as well.
 
 Some highlights:
 
 ASoC:
 - Preparatory work for merging the audio-graph and audio-graph-scu
   cards
 - A merge of TI OMAP and DaVinci directories, as both product lines
   get merged together.  Also including a few architecture changes as
   well.
 - Major cleanups of the Maxim MAX9867 driver
 - Small fixes for tablets & co with Intel BYT/CHT chips
 - Lots of rsnd updates as usual
 - Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
   RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S
   controllers
 
 HD-audio:
 - Introduce audio-mute LED trigger for replacing the former hackish
   dynamic binding
 - Huawei WMI hotkey and mute LED support
 - Refactoring of PM code and display power controls
 - Headset button support in the generic jack code
 - A few updates for Tegra
 - Fixups for HP EliteBook and ASUS UX391UA
 - Lots of updates for Intel ASoC HD-audio, including the improved DSP
   detection and the fallback binding from ASoC SST to legacy HD-audio
   controller drivers
 
 Others:
 - Updates for FireWire TASCAM and Fireface devices, some other fixes
 - A few potential Spectre v1 fixes that are all trivial

c76cd634eb platform-drivers-x86 for v4.21-1 
The USB Power Delivery discrete components now can be enumerated by
 i2c-multi-instantiate driver via several resources under single ACPI
 device node (ACPI ID is INT3515).
 
 Touchscreen support is added for the Mediacom Flexbook Edge 11.
 
 Mellanox driver got fixed due to updates in their firmware.
 
 The power management stub driver for AtomISP v2 is fixed in order to support
 Intel Baytrail SoCs where same quirk is needed for S0ix to work.
 
 Special key handling has been fixed for Favorites hotkey on Thinkpad, and
 Screen LOCK on ASUS.
 
 Ideapad Yoga 2 13 has no HW rfkill switch, thus, driver has been updated
 to support this.
 
 Few cleanups related to debugfs have been made in Intel IPS and
 Intel PMC drivers. Besides that Intel PMC has been extended
 to show more detailed information about Latency Tolerance.
 
 The following is an automated git shortlog grouped by driver:

Merge tag 'platform-drivers-x86-v4.21-1' of git://git.infradead.org/linux-platform-drivers-x86

Pull x86 platform driver updates from Andy Shevchenko:

 - The USB Power Delivery discrete components now can be enumerated by
   i2c-multi-instantiate driver via several resources under single ACPI
   device node (ACPI ID is INT3515).

 - Touchscreen support is added for the Mediacom Flexbook Edge 11.

 - Mellanox driver got fixed due to updates in their firmware.

 - The power management stub driver for AtomISP v2 is fixed in order to
   support Intel Baytrail SoCs where same quirk is needed for S0ix to
   work.

 - Special key handling has been fixed for Favorites hotkey on Thinkpad,
   and Screen LOCK on ASUS.

 - Ideapad Yoga 2 13 has no HW rfkill switch, thus, driver has been
   updated to support this.

 - Few cleanups related to debugfs have been made in Intel IPS and Intel
   PMC drivers. Besides that Intel PMC has been extended to show more
   detailed information about Latency Tolerance

Those files are meant to be dual GPL 2.0 and GFDL without
implicit sections. However, by a wrong cut-and-paste, I ended
by applying a GPL 2+ license text to it, while still using the
GPL 2.0 SPDX tag, with would cause an ambiguity about the
licensing model.

Solve this by explicitly mentioning that the dual licensing
is between GPL 2.0 and GFDL and correcting the text.

ASoC: q6asm-dai: dt-bindings: Add support to compress dais 
This patch adds board specific bindings required for dais, In particular
for compressed dais and dai direction.

Board specific setup involves setting up some of dais as compressed dais
and also specify direction of any dai. Some of the dais might only
support capture/playback depending on the board level wiring.

These two new dt properties will allow such flexibilty at board level dts.

0f5ab411f5 dt-bindings: clock: add imx8qxp lpcg clock binding 
The Low-Power Clock Gate (LPCG) modules contain a local programming
model to control the clock gates for the peripherals. An LPCG module
is used to locally gate the clocks for the associated peripheral.

Note:
This level of clock gating is provided after the clocks are generated
by the SCU resources and clock controls. Thus even if the clock is
enabled by these control bits, it might still not be running based
on the base resource.

7c813152cf dt-bindings/gic-v3: Add msm8996 compatible string 
Access to GICR_WAKER is restricted on msm8996 SoC in Hypervisor.
There are many devices out there with this restriction in place
and there has been no update to this firmware since last few years,
making those devices totally unusable for upstream development.

IIDR register value conflicts with other SoCs, using compatible seems
to be the only way to apply quirks required for msm8996 based SoCs.

Without this quirk many qcom SoCs (atleast 3 that I know) are
unable to boot mainline.

dt-bindings: mfd: axp20x: Add software based soft_start for AXP209 LDO3 
In the past, there have been words on various lists that if LDO3 is
disabled in u-boot, but enabled in the DTS, the axp209 driver would
fail to continue/hang. Several enable/disable patches have been
issues to devicetree's in both the kernel and u-boot to address
this issue.

What really happened however, was that the AXP209 shuts down without
a notice and without setting an interrupt. This is caused when LDO3
gets overloaded, for example with large capacitors on the LDO3 output.

Normally, we would expect that AXP209 would source 200 mA as per
datasheet and set and trigger an interrupt when being overloaded.
For some reason however, this does not happen.

As a work-around, implement software-based 'regulator-soft-start'
property for AXP209 LDO3 regulator, which is used to first bring up
the LDO3 to the lowest possible voltage and then enable the LDO.

After that, we can set the requested voltage as usual.

Combining this setting with the regulator-ramp-delay allows LDO3 to
come up slowly and staggered, potentially reducing overall inrush current.

dt-bindings: mfd: axp20x: add support for regulator-ramp-delay for AXP209 
The AXP209 supports ramping up voltages on several regulators such as
DCDC2 and LDO3, therefore we can use the standard 'regulator-ramp-delay'
property for those 2 regulators.

Note that the voltage ramp only works when the regulator is already
enabled. E.g. when going from say 0.7 V to 3.6 V.

When turning on the regulator, no voltage ramp is performed in hardware.

What this means, is that if the bootloader brings up the voltage at 0.7 V,
the ramp delay property is properly applied. If however, the bootloader
leaves the power off, no ramp delay is applied when the power is
enabled by the regulator framework.
