398e347987 dt-bindings: iio: adc: Remove the property "aspeed,trim-data-valid"
If the property is set on a device without valid trimming data in the OTP
the ADC will not function correctly. Therefore, this patch drops the use
of this property to avoid this scenario.

8013738845 dt-bindings: iio: adc: use spi-peripheral-props.yaml
Instead of listing directly properties typical for SPI peripherals,
reference the spi-peripheral-props.yaml schema.  This allows using all
properties typical for SPI-connected devices, even these which device
bindings author did not tried yet.

Remove the spi-* properties which now come via spi-peripheral-props.yaml
schema, except for the cases when device schema adds some constraints
like maximum frequency.

While changing additionalProperties->unevaluatedProperties, put it in
typical place, just before example DTS.

Pull char / misc / other smaller driver subsystem updates from Greg KH:
 "Here is the large set of char, misc, and other driver subsystem
  updates for 5.19-rc1. The merge request for this has been delayed as I
  wanted to get lots of linux-next testing due to some late arrivals of
  changes for the habannalabs driver.

  Highlights of this merge are:

   - habanalabs driver updates for new hardware types and fixes and
     other updates

   - IIO driver tree merge which includes loads of new IIO drivers and
     cleanups and additions

   - PHY driver tree merge with new drivers and small updates to
     existing ones

   - interconnect driver tree merge with fixes and updates

   - soundwire driver tree merge with some small fixes

   - coresight driver tree merge with small fixes and updates

   - mhi bus driver tree merge with lots of updates and new device
     support

   - firmware driver updates

   - fpga driver updates

   - lkdtm driver updates (with a merge conflict, more on that below)

   - extcon driver tree merge with small updates

   - lots of other tiny driver updates and fixes and cleanups, full
     details in the shortlog.

  All of these have been in linux-next for almost 2 weeks with no
  reported problems"

* st,accel:
  -  Add ID for lis302dl.
* st,lsm6dsx
  - Add support for ASM330LHHX (can fallback to LSM6DSR.)

Features

Cleanup and minor fixes
* MAINTAINERS
  - Update Lorenzo Bianconi's email address for IIO drivers.
  - Add entry for ad3552r and update maintainer in dt-binding doc.
* tree-wide
  - Replace strtobool() with kstrtobool().
  - Drop false OF dependencies.
* core
  - Tidy up and document IIO modes.
  - Take iio_buffer_enabled() out of header allowing current_mode to be
    moved to the opaque structure.
  - As all kfifo buffers use the same mode value, drop that parameter
    and set it unconditionally.
  - White space fixes and similar.
  - Drop use of list iterator variable for
    list_for_each_entry_continue_reverse and use list_prepare_entry to
    restart.
* sysfs-trigger
  - Replace use of 'found' variable with dedicate list iterator variable.
* adi,ad7124
  - Drop misleading shift.
* adi,ad2s1210

  - Add proximity-near-level binding and driver support.
* st,st_sensors:
  - Drop unused accel_type enum.
  - Return early in *_write_raw()
  - Drop unnecessary locking in _avail functions.
  - Add local lock to protect odr against concurrent updates allowing
    mlock to no longer be used outside of the core.
  - Use iio_device_claim_direct_mode() rather than racy checking of
    the current mode.
* st,stmpe-adc
  - Fix checks on wait_for_completion_timeout().
  - Allow use of of_device_id for matching.
* st,stm32-dfsdm
  - Stop accessing iio_dev->current_mode to find out if the buffer
    is enabled (so we can hide that variable in the opaque structure)
* st,vl53l0x
  - Fix checks on wait_for_completion_timeout.
* ti,ads1015
  - Add missing ID for ti,ads1115 in binding doc.
  - Convert from repeated chip ID look up to selecting static const
    data.
  - Switch to read_avail() callback.
* ti,ads8688
  - Use of_device_id for driver matching.
* ti,palmas-adc
  - Drop a warning on minor calibration mismatch leading to slightly
    negative values after applying the calibration.

If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.

27e4a85cf7 dt-bindings: Fix incomplete if/then/else schemas
A recent review highlighted that the json-schema meta-schema allows any
combination of if/then/else schema keywords even though if, then or else
by themselves makes little sense. With an added meta-schema to only
allow valid combinations, there's a handful of schemas found which need
fixing in a variety of ways. Incorrect indentation is the most common
issue.

The atmel,trigger-edge-type was never imposed by the driver.
Make things right and remove this property from the mandatory list.
This will not break existing nodes because according to the binding they
should have this property.
However, the driver does not impose it and it works without it, the property
selects the trigger type, and without it, the driver will have no trigger
available, which is the case on some boards which do not have access
to the trigger pin.
This will avoid generating this warning for example:

Jonathan writes:

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.
  - adi,ad7266
  - bosch,bma220
  - fsl,mac3110
  - fsl,mma7455
  - fsl,mpl3115
  - kionix,kcjk-1013
  - sensortek,stk8ba50
  - sensortek,stk8312
  - ti,adc12138
  - ti,ads1015
  - vti,sca3000
  - xilinx,xadc-core
* Switch drives over to generic firmware properties including appropriate
  header changes to avoid including of.h
  - Various DACs had false CONFIG_OF dependencies.
  - dpot-dac
  - envelope-detector
  - adi,ad5755
  - adi,ad5758
  - capella,cm3605
  - maxim,max9611
  - microchip,mcp41010
  - microchip,mcp3911
  - ti,adc12138
* Trivial clang warning fixes for W=1 warnings.

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.
* renesas,rzg2l
  - Drop a dev_err() that just duplicates error printed in platform_get_irq()
* sgx,vz89x
  - Drop pointless cast.
* st,lsm6dsx
  - Make it possible to disable the sensorhub from DT to avoid a corner
    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
     over-reading (harmless). Precursor to enabling -Warray-bounds.
* ti,adc081c
  - Put back some ACPI support for non standards compliant ADC081C
    ID because it is known to be in the wild on some Aaeon boards.
* ti,ads8688
  - Cleanup redundant local ret variable assignment.
* ti,ina2xx-adc
  - Use helper macro kthread_run() to replace some boilerplate.
  - Avoid double reference counting.
  - Drop pointless cast.
* xilinx,xadc
  - Make the IRQ optional as not always wired to the host system.
