8f56e4ebe0 Char/Misc driver patches for 5.5-rc1
Here is the big set of char/misc and other driver patches for 5.5-rc1
 
 Loads of different things in here, this feels like the catch-all of
 driver subsystems these days.  Full details are in the shortlog, but
 nothing major overall, just lots of driver updates and additions.
 
 All of these have been in linux-next for a while with no reported
 issues.

3f1b210a7f sound updates for 5.5-rc1
There have been some significant changes in the core side, both for
 ALSA and ASoC, while lots of development have been seen in SOF, as
 well as many small fixes/improvements for ASoC codecs and platforms.
 Below is a highlight in this cycle:
 
 Core:
 - The unification of PCM vmalloc buffer allocation helpers into the
   standard API
 - Clean up of the default PCM mmap handling for vmalloc & SG-buffer
 - Fix potential races at ALSA timer open
 - A few new PCM API extensions; just preliminary core changes, the
   actual changes in drivers will be merged in 5.6
 - Continued ASoC componentization works; now almost everything is a
   common ASoC component object.  A lot of refactoring and
   simplification have been done along with it.
 
 ASoC:
 - Many fixes to the Sound Open Firmware (SOF) code
 - Wake on voice support for Chromebooks
 - SPI support and trigger word detection for RT5677
 - New drivers for Analog Devices ADAU7118, Intel Cannonlake systems
   with RT1011 and RT5682, Texas Instruments TAS2562 and TAS2770
 
 HD-audio:
 - Improved Intel DSP configuration / probe code for SOF
 - Plumbing the legacy HD-audio driver with Intel SOF HDMI
 - DP-MST support for Nvidia HDMI codecs
 - Realtek quirks cleanups and new additions as usual
 
 Others:
 - Lots of refactoring and cleanups for FireWire; period-size sharing,
   h/w IRQ interval configuration, clock recovery improvements, etc
 - USB-audio: Scarlett mixer quirks
 - Cleanups of PCM calls in various drivers (including media and USB)
   to adapt the core API changes

832392db97 platform/x86: i2c-multi-instantiate: Fail the probe if no IRQ provided
For APIC case of interrupt we don't fail a ->probe() of the driver,
which makes kernel to print a lot of warnings from the children.

We have two options here:
- switch to platform_get_irq_optional(), though it won't stop children
  to be probed and failed
- fail the ->probe() of i2c-multi-instantiate

Since the in reality we never had devices in the wild where IRQ resource
is optional, the latter solution suits the best.

on HAS_IOMEM and HAS_DMA which is sufficient for all Goldfish devices.

71eea70715 platform/x86: intel_punit_ipc: Avoid error message when retrieving IRQ
Since the commit

  7723f4c5ec ("driver core: platform: Add an error message to platform_get_irq*()")

the platform_get_irq() started issuing an error message which is not
what we want here.

Switch to platform_get_irq_optional() to have only warning message
provided by the driver.

MIPS: Loongson: Add Loongson-3A R4 basic support
All Loongson-3 CPU family:

Code-name         Brand-name       PRId
Loongson-3A R1    Loongson-3A1000  0x6305
Loongson-3A R2    Loongson-3A2000  0x6308
Loongson-3A R2.1  Loongson-3A2000  0x630c
Loongson-3A R3    Loongson-3A3000  0x6309
Loongson-3A R3.1  Loongson-3A3000  0x630d
Loongson-3A R4    Loongson-3A4000  0xc000
Loongson-3B R1    Loongson-3B1000  0x6306
Loongson-3B R2    Loongson-3B1500  0x6307

Features of R4 revision of Loongson-3A:

  - All R2/R3 features, including SFB, V-Cache, FTLB, RIXI, DSP, etc.
  - Support variable ASID bits.
  - Support MSA and VZ extensions.
  - Support CPUCFG (CPU config) and CSR (Control and Status Register)
      extensions.
  - 64 entries of VTLB (classic TLB), 2048 entries of FTLB (8-way
      set-associative).

Now 64-bit Loongson processors has three types of PRID.IMP: 0x6300 is
the classic one so we call it PRID_IMP_LOONGSON_64C (e.g., Loongson-2E/
2F/3A1000/3B1000/3B1500/3A2000/3A3000), 0x6100 is for some processors
which has reduced capabilities so we call it PRID_IMP_LOONGSON_64R
(e.g., Loongson-2K), 0xc000 is supposed to cover all new processors in
general (e.g., Loongson-3A4000+) so we call it PRID_IMP_LOONGSON_64G.

24a8d78a9a platform/x86: i2c-multi-instantiate: Derive the device name from parent
When naming the new devices, instead of using the ACPI ID in
the name as base, using the parent device's name. That makes
it possible to support multiple multi-instance i2c devices
of the same type in the same system.

This fixes an issue seen on some Intel Kaby Lake based
boards:

sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-0/i2c-INT3515-tps6598x.0'

1f7d290a72 Driver core patches for 5.4-rc1
Here is the big driver core update for 5.4-rc1.
 
 There was a bit of a churn in here, with a number of core and OF
 platform patches being added to the tree, and then after much discussion
 and review and a day-long in-person meeting, they were decided to be
 reverted and a new set of patches is currently being reviewed on the
 mailing list.
 
 Other than that churn, there are two "persistent" branches in here that
 other trees will be pulling in as well during the merge window.  One
 branch to add support for drivers to have the driver core automatically
 add sysfs attribute files when a driver is bound to a device so that the
 driver doesn't have to manually do it (and then clean it up, as it
 always gets it wrong).
 
 There's another branch in here for generic lookup helpers for the driver
 core that lots of busses are starting to use.  That's the majority of
 the non-driver-core changes in this patch series.
 
 There's also some on-going debugfs file creation cleanup that has been
 slowly happening over the past few releases, with the goal to hopefully
 get that done sometime next year.
 
 All of these have been in linux-next for a while now with no reported
 issues.

- Rework the main suspend-to-idle control flow to avoid repeating
    "noirq" device resume and suspend operations in case of spurious
    wakeups from the ACPI EC and decouple the ACPI EC wakeups support
    from the LPS0 _DSM support (Rafael Wysocki).
 
  - Extend the wakeup sources framework to expose wakeup sources as
    device objects in sysfs (Tri Vo, Stephen Boyd).
 
  - Expose system suspend statistics in sysfs (Kalesh Singh).
 
  - Introduce a new haltpoll cpuidle driver and a new matching
    governor for virtualized guests wanting to do guest-side polling
    in the idle loop (Marcelo Tosatti, Joao Martins, Wanpeng Li,
    Stephen Rothwell).
 
  - Fix the menu and teo cpuidle governors to allow the scheduler tick
    to be stopped if PM QoS is used to limit the CPU idle state exit
    latency in some cases (Rafael Wysocki).
 
  - Increase the resolution of the play_idle() argument to microseconds
    for more fine-grained injection of CPU idle cycles (Daniel Lezcano).
 
  - Switch over some users of cpuidle notifiers to the new QoS-based
    frequency limits and drop the CPUFREQ_ADJUST and CPUFREQ_NOTIFY
    policy notifier events (Viresh Kumar).
 
  - Add new cpufreq driver based on nvmem for sun50i (Yangtao Li).
 
  - Add support for MT8183 and MT8516 to the mediatek cpufreq driver
    (Andrew-sh.Cheng, Fabien Parent).
 
  - Add i.MX8MN support to the imx-cpufreq-dt cpufreq driver (Anson
    Huang).
 
  - Add qcs404 to cpufreq-dt-platdev blacklist (Jorge Ramirez-Ortiz).
 
  - Update the qcom cpufreq driver (among other things, to make it
    easier to extend and to use kryo cpufreq for other nvmem-based
    SoCs) and add qcs404 support to it  (Niklas Cassel, Douglas
    RAILLARD, Sibi Sankar, Sricharan R).
 
  - Fix assorted issues and make assorted minor improvements in the
    cpufreq code (Colin Ian King, Douglas RAILLARD, Florian Fainelli,
    Gustavo Silva, Hariprasad Kelam).
 
  - Add new devfreq driver for NVidia Tegra20 (Dmitry Osipenko, Arnd
    Bergmann).
 
  - Add new Exynos PPMU events to devfreq events and extend that
    mechanism (Lukasz Luba).
 
  - Fix and clean up the exynos-bus devfreq driver (Kamil Konieczny).
 
  - Improve devfreq documentation and governor code, fix spelling

Pull power management updates from Rafael Wysocki:
 "These include a rework of the main suspend-to-idle code flow (related
  to the handling of spurious wakeups), a switch over of several users
  of cpufreq notifiers to QoS-based limits, a new devfreq driver for
  Tegra20, a new cpuidle driver and governor for virtualized guests, an
  extension of the wakeup sources framework to expose wakeup sources as
  device objects in sysfs, and more.

  Specifics:

   - Rework the main suspend-to-idle control flow to avoid repeating
     "noirq" device resume and suspend operations in case of spurious
     wakeups from the ACPI EC and decouple the ACPI EC wakeups support
     from the LPS0 _DSM support (Rafael Wysocki).

   - Extend the wakeup sources framework to expose wakeup sources as
     device objects in sysfs (Tri Vo, Stephen Boyd).

   - Expose system suspend statistics in sysfs (Kalesh Singh).

   - Introduce a new haltpoll cpuidle driver and a new matching governor
     for virtualized guests wanting to do guest-side polling in the idle
     loop (Marcelo Tosatti, Joao Martins, Wanpeng Li, Stephen Rothwell).

   - Fix the menu and teo cpuidle governors to allow the scheduler tick
     to be stopped if PM QoS is used to limit the CPU idle state exit
     latency in some cases (Rafael Wysocki).

   - Increase the resolution of the play_idle() argument to microseconds
     for more fine-grained injection of CPU idle cycles (Daniel
     Lezcano).

   - Switch over some users of cpuidle notifiers to the new QoS-based
     frequency limits and drop the CPUFREQ_ADJUST and CPUFREQ_NOTIFY
     policy notifier events (Viresh Kumar).

   - Add new cpufreq driver based on nvmem for sun50i (Yangtao Li).

   - Add support for MT8183 and MT8516 to the mediatek cpufreq driver
     (Andrew-sh.Cheng, Fabien Parent).

   - Add i.MX8MN support to the imx-cpufreq-dt cpufreq driver (Anson
     Huang).

   - Add qcs404 to cpufreq-dt-platdev blacklist (Jorge Ramirez-Ortiz).

   - Update the qcom cpufreq driver (among other things, to make it
     easier to extend and to use kryo cpufreq for other nvmem-based
     SoCs) and add qcs404 support to it (Niklas Cassel, Douglas
     RAILLARD, Sibi Sankar, Sricharan R).

   - Fix assorted issues and make assorted minor improvements in the
     cpufreq code (Colin Ian King, Douglas RAILLARD, Florian Fainelli,
     Gustavo Silva, Hariprasad Kelam).

   - Add new devfreq driver for NVidia Tegra20 (Dmitry Osipenko, Arnd
     Bergmann).

   - Add new Exynos PPMU events to devfreq events and extend that
     mechanism (Lukasz Luba).

   - Fix and clean up the exynos-bus devfreq driver (Kamil Konieczny).

   - Improve devfreq documentation and governor code, fix spelling typos
     in devfreq (Ezequiel Garcia, Krzysztof Kozlowski, Leonard Crestez,
     MyungJoo Ham, Gaël PORTAY).

   - Add regulators enable and disable to the OPP (operating performance
     points) framework (Kamil Konieczny).

   - Update the OPP framework to support multiple opp-suspend properties
     (Anson Huang).

   - Fix assorted issues and make assorted minor improvements in the OPP
     code (Niklas Cassel, Viresh Kumar, Yue Hu).

   - Clean up the generic power domains (genpd) framework (Ulf Hansson).

   - Clean up assorted pieces of power management code and documentation
     (Akinobu Mita, Amit Kucheria, Chuhong Yuan).

   - Update the pm-graph tool to version 5.5 including multiple fixes
     and improvements (Todd Brandt).

   - Update the cpupower utility (Benjamin Weis, Geert Uytterhoeven,
     Sébastien Szymanski)"

bbfe0d6b8b This is the bulk of changes in the GPIO subsystem for the
v5.4 kernel cycle.
 
 Core changes:
 
 - Support hierarchical GPIO irqchips. We now have three
   consumers that can use this: Intel IXP4xx, ThunderX and
   Qualcomm SPMI GPIO (in the pinctrl subsystem). The support
   code has been long in the making and hashed out so it should
   be easily adaptable for all hierarchical irqchip parents.
   The code only gets compiled in if hierarchical irqchip
   is used at the topmost irq controller at least, as the
   hierarchical irqchip requires strict hierarchy all the
   way up in the system.
 
 - Determine the need for a "valid_mask" for GPIO lines on the
   gpio_chip and conversely for the "valid_mask" for the GPIO
   interrupt chip interrupt lines by looking for a
   .init_valid_mask() callback in the main chip or GPIO interrupt
   chip respectively. Allocate it with bitmap_alloc().
 
 - Isolate the device tree/open firmware GPIO description code
   out in its own file properly.
 
 - Isolate the ACPI GPIO description code out in its own file
   properly.
 
 - Drop a whole lot of #ifdef:s in the main includes: it does
   not hurt to keep the include items around, and we get
   quicker and clearer compile failures if the appropriate
   kernel symbols are not selected for drivers.
 
 New/deleted drivers:
 
 - New driver for Aspeed SGPIO.
 
 - The KS8695 driver is deleted as the platform gets deleted
   from arch/arm in this kernel cycle.
 
 - The Cirrus Logic Madera driver now supports CS47L92 and
   CS47L15.
 
 - The Freescale MPC8xxx now supports LS1028A and LS1088A.
 
 Driver improvements:
 
 - We pass the GPIO irqchip intialization by directly filling
   in the struct instead of using set-up functions (the new
   way) for Intel MID, Lynxpoint, Merrifield, XLP, HLWD, Aspeed,
   ZX, VF610, TQMX86, MT7621, Zynq and EP93xx.
 
 Out-of-band changes:
 
 - Fix a GPIO header inclusion in Unicore - no response from
   maintainer.
 
 - Drop FMC subsystem from MAINTAINERS - was deleted in the
   GPIO tree last cycle so let's mop up the shards.

     its own file properly.

   - Isolate the ACPI GPIO description code out in its own file
     properly.

   - Drop a whole lot of #ifdef:s in the main includes: it does not hurt
     to keep the include items around, and we get quicker and clearer
     compile failures if the appropriate kernel symbols are not selected
     for drivers.

  New/deleted drivers:

   - New driver for Aspeed SGPIO.

   - The KS8695 driver is deleted as the platform gets deleted from
     arch/arm in this kernel cycle.

   - The Cirrus Logic Madera driver now supports CS47L92 and CS47L15.

   - The Freescale MPC8xxx now supports LS1028A and LS1088A.

  Driver improvements:

   - We pass the GPIO irqchip intialization by directly filling in the
     struct instead of using set-up functions (the new way) for Intel
     MID, Lynxpoint, Merrifield, XLP, HLWD, Aspeed, ZX, VF610, TQMX86,
     MT7621, Zynq and EP93xx.

  Out-of-band changes:

   - Fix a GPIO header inclusion in Unicore - no response from
     maintainer.

   - Drop FMC subsystem from MAINTAINERS - was deleted in the GPIO tree
     last cycle so let's mop up the shards"

85624f90c8 platform/x86: asus-wmi: Make it depend on ACPI battery API
When driver has been switched to use ACPI battery API in the commit

  7973353e92 ("Refactor charge threshold to use the battery hooking API")

it makes it implicitly dependent to a corresponding kernel configuration
option.

Make this dependency explicit in Kconfig.

96a0a80738 platform/chrome: cros_ec_chardev: Add a poll handler to receive MKBP events
Allow to poll on the cros_ec device to receive the MKBP events.

The /dev/cros_[ec|fp|..] file operations now implements the poll
operation. The userspace can now receive specific MKBP events by doing
the following:

- Open the /dev/cros_XX file.
- Call the CROS_EC_DEV_IOCEVENTMASK ioctl with the bitmap of the MKBP
  events it wishes to receive as argument.
- Poll on the file descriptor.
- When it gets POLLIN, do a read on the file descriptor, the first
  queued event will be returned (using the struct
  ec_response_get_next_event format: one byte of event type, then
  the payload).

The read() operation returns at most one event even if there are several
queued, and it might be truncated if the buffer is smaller than the
event (but the caller should know the maximum size of the events it is
reading).

read() used to return the EC version string, it still does it when no
event mask or an empty event is set for backward compatibility (despite
nobody really using this feature).

This will be used, for example, by the userspace daemon to receive and
treat the EC_MKBP_EVENT_FINGERPRINT sent by the FP MCU.

71cddb7097 platform/chrome: cros_ec_rpmsg: Fix race with host command when probe failed
Since the rpmsg_endpoint is created before probe is called, it's
possible that a host event is received during cros_ec_register, and
there would be some pending work in the host_event_work workqueue while
cros_ec_register is called.

If cros_ec_register fails, when the leftover work in host_event_work
run, the ec_dev from the drvdata of the rpdev could be already set to
NULL, causing kernel crash when trying to run cros_ec_get_next_event.

Fix this by creating the rpmsg_endpoint by ourself, and when
cros_ec_register fails (or on remove), destroy the endpoint first (to
make sure there's no more new calls to cros_ec_rpmsg_callback), and then
cancel all works in the host_event_work workqueue.

5fbe5b5883 gpio: Initialize the irqchip valid_mask with a callback
After changing the valid_mask for the struct gpio_chip
to detect the need and presence of a valid mask with the
presence of a .init_valid_mask() callback to fill it in,
we augment the gpio_irq_chip to use the same logic.

Switch all driver using the gpio_irq_chio valid_mask
over to this new method.

This makes sure the valid_mask for the gpio_irq_chip gets
filled in when we add the gpio_chip, which makes it a
little easier to switch over drivers using the old
way of setting up gpio_irq_chip over to the new method
of passing the gpio_irq_chip along with the gpio_chip.
(See drivers/gpio/TODO for details.)

1bd43d0077 platform/x86: intel_int0002_vgpio: Fix wakeups not working on Cherry Trail
Commit 871f1f2bcb ("platform/x86: intel_int0002_vgpio: Only implement
irq_set_wake on Bay Trail") removed the irq_set_wake method from the
struct irq_chip used on Cherry Trail, but it did not set
IRQCHIP_SKIP_SET_WAKE causing  kernel/irq/manage.c: set_irq_wake_real()
to return -ENXIO.

This causes the kernel to no longer see PME events reported through the
INT0002 device as wakeup events. Which e.g. breaks wakeup by the (USB)
keyboard on many Cherry Trail 2-in-1 devices.
