IIO: New device support, features and cleanup for 6.18

New device support
==================

ad,ade9000
- New driver for this complex energy and power monitoring ADC.
infineon,tlv493d
- New driver for this 3D magnetic sensor.
intel,dollar
- New driver for this TI PMIC (part number unknown)
marvel,88pm886
- Driver for this PMIC ADC.
microchip,mcp9600
- Add explicit support for the mcp9601 which has some additional features
  over the mcp9600.
rohm,bd79112
- New driver for this ADC / GPIO Chip.

Features
========
Core
- New helper to multiply data expressed in IIO types.
- Add KUnit tests.
- New IIO_ALTCURRENT type, similar to existing IIO_ALTVOLTAGE
- Add some channel modifiers related to energy and power, such as
  reactive.
adi,ad7124
- Support external clocks sources and output of the internal clocks.
- Filter control.
adi,ad7173
- Add filter support. Some fiddly interactions with other parameters on this
  device.
adi,ad7779
- Add backend support which required control of the number of lanes used.
liteon,ltr390
- Add runtime PM support.
microchip,mcp9600
- Add support for different thermocouple types.

Cleanup and minor fixes
=======================

core
- Switch info_mask fields to be unsigned. Not clear why they were ever
  signed.
- Fix handling of negative channel scale in iio_convert_raw_to_processed()
- Fix offset handling for channels without a scale attribute.
- Improve the precision of scaling slightly.
- Drop apparent handling of IIO_CHAN_INFO_PROCESSED for devices that don't
  have any such channels.
various
- Drop many pm_runtime_mark_last_busy() calls now
  pm_runtime_put_autosuspend() calls it internally.
- Drop dev_err_probe() calls where the error code is hard coded as -ENOMEM
  as they don't do anything.
- Drop dev_err() calls where the error code is -ENOMEM. This will reduce
  error prints, but memory failures generate a lot of messages anyway
  so unlikely we need these prints.
current-sense-amplifier
- Add #io-channels property this channel to be used by a consumer driver.
adi,ad7124
- Fix incorrect clocks dt-binding property.
- Make the mclk clock optional in DT - this is internal to the ADC so should
  never have been in he binding.
- Fix up sample rate to comply with ABI.
- Use read_avail() callback rather than opencoding similar.
- Deploy guard() to clean up some lock handling.
adi,ad7768
- Use devm_regulator_get_enable_read_voltage() to replace similar code.
adi,ad7816
- Drop an unnecessary dev_set_drvdata() call as nothing uses the data.
ad,adxl345
- Fix missing blank line before bullet list in documentation.
arm,scmi
- Use devm_kcalloc() for an array allocation rather than devm_kzalloc().
bosch,bmi270
- Match an ACPI ID seen in the wild. It is not spec compliant but we can't
  do much about that.
bosch,bmp280
- Drop overly noisy dev_info()
- Allow for sleeping gpio controllers.
gogle,cros-ec
- Drop unused location attribute that has been replaced by label.
invense,icm42600
- Simplify the power management.
- Use guard() to simplify some locking.
maxim,max1238
- Add io-channel-cells property to dt-binding as there is an in tree
  consumer.
microchip,mcp9600
- Specify a default value in dt-binding for the thermocouple type
- General whitespace cleanup.
samsung,exynos
- Drop support for the S3C2410 including bindings, and touchscreen support
  as nothing else uses that.
- Drop platform ID based binding as not used.
st,vl53l0x
- Fix returning the wrong variable in an error path.
ti,pac1934
- Replace open coded devm_mutex_init().
xilinx,ams
- Update maintainers entry.
