a3c8f906ed platform/x86/intel: Move intel_pmt from MFD to Auxiliary Bus
Intel Platform Monitoring Technology (PMT) support is indicated by presence
of an Intel defined PCIe Designated Vendor Specific Extended Capabilities
(DVSEC) structure with a PMT specific ID. The current MFD implementation
creates child devices for each PMT feature, currently telemetry, watcher,
and crashlog. However DVSEC structures may also be used by Intel to
indicate support for other features. The Out Of Band Management Services
Module (OOBMSM) uses DVSEC to enumerate several features, including PMT.
In order to support them it is necessary to modify the intel_pmt driver to
handle the creation of the child devices more generically. To that end,
modify the driver to create child devices for any VSEC/DVSEC features on
supported devices (indicated by PCI ID).  Additionally, move the
implementation from MFD to the Auxiliary bus.  VSEC/DVSEC features are
really multifunctional PCI devices, not platform devices as MFD was
designed for. Auxiliary bus gives more flexibility by allowing the
definition of custom structures that can be shared between associated
auxiliary devices and the parent device. Also, rename the driver from
intel_pmt to intel_vsec to better reflect the purpose.

This series also removes the current runtime pm support which was not
complete to begin with. None of the current devices require runtime pm.
However the support will be replaced when a device is added that requires
it.

1bb866dcb8 1st set of IIO new device support, features and cleanup for 5.17
Includes some fixes that were either late breaking, low priority or
 complex enough to not be good to rush in late in the cycle.
 
 Tree rebased today to fix up some trivial issues + pull in a fix that
 was previously on the fixes-togreg branch. Vast majority have been
 in linux-next for some time now.
 
 New device support
 * adi,ad7293
   - New driver and bindings for this Power Amplifier drain current
     controller.  A complex device with various related monitoring functions.
 * adi,ad75513R
   - New driver and bindings for this combined ADC and DAC device.
   - A few follow up fixes.
 * adi,admv8818
   - New driver (and type) for this 2-18GHz filter device. Includes
     bindings and ABI documentation to allow clk_notifier based auto
     adjustment of the filters in appropriate applications.
 * liteon,ltr501
   - Support for the ltr303.  ID and chip specific info table.
 * xilinx,ams
   - New generic firmware function fwnode_iomap() as used in this driver.
   - New driver and bindings for this ADC and on-chip sensors as found
     in various Xilinx devices.
 
 Core
 * Introduced IIO_VAL_INT_64 which uses val and val2 in IIO callbacks to
   form a 64 bit integer when higher precision needed.
 * Allow IIO_ENUM_AVAILABLE to be used with different shared values.
 * Fix a long term issue with scheduling whilst atomic when iio_trig_poll()
   is called but no trigger consumers are actually enabled and hence the
   trigger may be reenabled from the interrupt handler.  Seen in the wild
   on the tsc2046.
 * Mark iio_device_type const.
 * buffer: Use a separate index variable to simplify code.
 * buffer-dma: Clear out unused struct iio_buffer_block
 * buffer-dmaengine: Switch to cheaper round_down() as power of 2 values.
 
 Tests/tools
 * format_value
   - Check against NULL returns from allocations in tests.
   - Add IIO_VAL_INT_64 test case.
 * event_monitor
   - Flush the output after event to given more consistent latency
     when tool output piped to other programs.
 
 Driver Features
 * axp20x
   - Add support for NTC thermistor channel and document TS pin binding.
 * arm,scmi
   - Add reading of raw channel values (using IIO_VAL_INT_64)
 * liteon,ltr501
   - Add proximity-near-level support and dt-binding.
 
 Tree wide cleanup
 * Remove no-op trigger ops from multiple drivers.
 * Stop using dev_get_drvdata() on the iio_dev->dev in various drivers
   and then stop assigning it to allow this to be used for other purposes.
   We can always get to the indio_dev using dev_to_iio_dev() which is
   a container_of() based approach. Also cleanup up some related unnecessary
   convoluted cases.
   - atmel,at91-sam5d2
   - nxp,imx7d
   - meas,ms5611
   - st,st_sensors
 * Where available (or easy to introduce) use the scan_type.* values
   in place of a second copy for read_raw and similar paths.

 Driver specific cleanup and minor fixes
 * adi,ad7606
   - Comment fixes.
 * ams,ad3935
   - Drop pointless cast to the same type.
 * atmel,at91-sama5d2
   - Fix wrong cast of iio_dev->dev to platform_device that happened to
     be harmless.
 * fsl,mma7660
   - Stop i2c remove() function returning an error code. Part of a rework
     to eventually stop returning anything from these.
 * fsl,mma8452
   - Use correct type for local irqreturn_t.
 * nxp,imx8mq
   - Maintainer email address update.
 * nxp,lpc18xx_adc
   - Ensure clk_prepare_enable() called before clk_get_rate().
   - Switch of.h for mod_devicetable.h to reflect no of specific functions,
     just the id table.

     case where the address of a slave device many be accidentally modified.
 * st,stm32-adc
   - Stop leaking an of_node in an error path.
 * st,stmp2
    - Avoid wrong sized type for bit field which could result in

 * ti,ina2xx-adc
   - Use helper macro kthread_run() to replace some boilerplate.
   - Avoid double reference counting.

9593bdfa1d Samsung SoC drivers changes for v5.17
1. Exynos ChipID: add Exynos7885 support.
 2. Exynos PMU: add Exynos850 support.
 3. Minor bindings cleanup.
 4. Add Exynos USIv2 (Universal Serial Interface) driver. The USI block is
    a shared IP block between I2C, UART/serial and SPI. Basically one has
    to choose which feature the USI block will support and later the
    regular I2C/serial/SPI driver will bind and work.
    This merges also one commit with dt-binding headers from my dts64
    pull request.
 
    Together with a future serial driver change, this will break the ABI.
 
    Affected: Serial on ExynosAutov9 SADK and out-of-tree ExynosAutov9 boards
 
    Why: To properly and efficiently support the USI with new hierarchy
    of USI-{serial,SPI,I2C} devicetree nodes.
 
    Rationale:
    Recently added serial and USI support was short-sighted and did not
    allow to smooth support of other features (SPI and I2C). Adding
    support for USI-SPI and USI-I2C would effect in code duplication.
    Adding support for different USI versions (currently supported is
    USIv2 but support for v1 is planned) would cause even more code
    duplication and create a solution difficult to maintain.
    Since USI-serial and ExynosAutov9 have been added recently, are
    considered fresh development features and there are no supported
    products using them, the code/solution is being refactored in
    non-backwards compatible way.  The compatibility is not broken yet.
    It will be when serial driver changes are accepted.
    The ABI break was discussed with only known users of ExynosAutov9 and
    received their permission.

Samsung SoC drivers changes for v5.17

1. Exynos ChipID: add Exynos7885 support.
2. Exynos PMU: add Exynos850 support.
3. Minor bindings cleanup.
4. Add Exynos USIv2 (Universal Serial Interface) driver. The USI block is
   a shared IP block between I2C, UART/serial and SPI. Basically one has
   to choose which feature the USI block will support and later the
   regular I2C/serial/SPI driver will bind and work.
   This merges also one commit with dt-binding headers from my dts64
   pull request.

   Together with a future serial driver change, this will break the ABI.

   Affected: Serial on ExynosAutov9 SADK and out-of-tree ExynosAutov9 boards

   Why: To properly and efficiently support the USI with new hierarchy
   of USI-{serial,SPI,I2C} devicetree nodes.

   Rationale:
   Recently added serial and USI support was short-sighted and did not
   allow to smooth support of other features (SPI and I2C). Adding
   support for USI-SPI and USI-I2C would effect in code duplication.
   Adding support for different USI versions (currently supported is
   USIv2 but support for v1 is planned) would cause even more code
   duplication and create a solution difficult to maintain.
   Since USI-serial and ExynosAutov9 have been added recently, are
   considered fresh development features and there are no supported
   products using them, the code/solution is being refactored in
   non-backwards compatible way.  The compatibility is not broken yet.
   It will be when serial driver changes are accepted.
   The ABI break was discussed with only known users of ExynosAutov9 and
   received their permission.

5fc1f93f69 clocksource/drivers: Add MStar MSC313e timer support
The MSC313e-compatible SoCs have 3 timer hardware blocks. All of these
are free running 32-bit increasing counters and can generate interrupts.
Based onto a maximum value register, each timer can either count from 0
to max, one time then stop (which generates interrupts) or can count
from 0 to max and then roll. This commit adds basic support for these
timers, the first timer block being used as clocksource/sched_clock
and delay, while the others will be used as clockevents.

ec648f6b76 pinctrl: starfive: Add pinctrl driver for StarFive SoCs
Add a combined pinctrl and GPIO driver for the JH7100 RISC-V SoC by
StarFive Ltd. This is a test chip for their upcoming JH7110 SoC, which
is said to feature only minor changes to these pinctrl/GPIO parts.

For each "GPIO" there are two registers for configuring the output and
output enable signals which may come from other peripherals. Among these
are two special signals that are constant 0 and constant 1 respectively.
Controlling the GPIOs from software is done by choosing one of these
signals. In other words the same registers are used for both pin muxing
and controlling the GPIOs, which makes it easier to combine the pinctrl
and GPIO driver in one.

I wrote the pinconf and pinmux parts, but the GPIO part of the code is
based on the GPIO driver in the vendor tree written by Huan Feng with
cleanups and fixes by Drew and me.

fea251b6a5 iio: addac: add AD74413R driver
The AD74412R and AD74413R are quad-channel, software configurable,
input/output solutions for building and process control applications.

They contain functionality for analog output, analog input, digital input,
resistance temperature detector, and thermocouple measurements integrated
into a single chip solution with an SPI interface.

The devices feature a 16-bit ADC and four configurable 13-bit DACs to
provide four configurable input/output channels and a suite of diagnostic
functions.

The AD74413R differentiates itself from the AD74412R by being
HART-compatible.

When configured with channel 0 as voltage output, channel 1 as current
output, channel 2 as voltage input and channel 3 as current input, the
following structure is created under the corresponding IIO device.

5aaf9efffc kselftest: alsa: Add simplistic test for ALSA mixer controls kselftest
Add a basic test for the mixer control interface. For every control on
every sound card in the system it checks that it can read and write the
default value where the control supports that and for writeable controls
attempts to write all valid values, restoring the default values after
each test to minimise disruption for users.

There are quite a few areas for improvement - currently no coverage of the
generation of notifications, several of the control types don't have any
coverage for the values and we don't have any testing of error handling
when we attempt to write out of range values - but this provides some basic
coverage.

This is added as a kselftest since unlike other ALSA test programs it does
not require either physical setup of the device or interactive monitoring
by users and kselftest is one of the test suites that is frequently run by
people doing general automated testing so should increase coverage. It is
written in terms of alsa-lib since tinyalsa is not generally packaged for
distributions which makes things harder for general users interested in
kselftest as a whole but it will be a barrier to people with Android.
