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.

+description: |
+  The AMS (Analog Monitoring System) includes an ADC as well as on-chip sensors
+  that can be used to sample external voltages and monitor on-die operating
+  conditions, such as temperature and supply voltage levels.
+  The AMS has two SYSMON blocks which are PL (Programmable Logic) SYSMON and
+  PS (Processing System) SYSMON.
+  All designs should have AMS registers, but PS and PL are optional. The
+  AMS controller can work with only PS, only PL and both PS and PL
+  configurations. Please specify registers according to your design. Devicetree
+  should always have AMS module property. Providing PS & PL module is optional.

+description: |
+  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.
