5b4e4b7203 iio: adc: rockchip_saradc: use mask for write_enable bitfield 
Some of the registers on the SARADCv2 have bits write protected except
if another bit is set. This is usually done by having the lowest 16 bits
store the data to write and the highest 16 bits specify which of the 16
lowest bits should have their value written to the hardware block.

The write_enable mask for the channel selection was incorrect because it
was just the value shifted by 16 bits, which means it would only ever
write bits and never clear them. So e.g. if someone starts a conversion
on channel 5, the lowest 4 bits would be 0x5, then starts a conversion
on channel 0, it would still be 5.

Instead of shifting the value by 16 as the mask, let's use the OR'ing of
the appropriate masks shifted by 16.

Note that this is not an issue currently because the only SARADCv2
currently supported has a reset defined in its Device Tree, that reset
resets the SARADC controller before starting a conversion on a channel.
However, this reset is handled as optional by the probe function and
thus proper masking should be used in the event an SARADCv2 without a
reset ever makes it upstream.

The SARADCv2 on RK3588 (the only SoC currently supported that has an

the 4 lowest bits, therefore the mask should be GENMASK(3, 0) and not

IIO: 1st set of new device support, features and cleanup for 6.9

IIO Backend support
===================

New approach from Nuno Sa to the problem of reuse of drivers with
IIO devices that are actually the combination of a highspeed chip
and an FPGA core handling the data capture and flows. It will hopefully
also apply to some other split designs. The ad9467 and axi-adi drivers
are converted over to this framework.

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

adi,admfm2000
- New driver for this dual microwave down converter.
ams,as73211
- Add support for as7331 UV sensor.
richtek,rtq6056
- Add support for related parts RTQ6053 and RTQ6059
st,lsm6dsx
- Add ASM330LHHXG1 accelerometer and gyro support (mainly IDs)
ti,ads1298
- New driver for this medical ADC.

Features
========

tests
- Unit tests for the gain-time-scale helper library.
bosch,bmi088
- I2C support.
bosh,bmi160
- Add 10EC5280 ACPI ID. Used in a number of devices that won't get fixed.
  The ID is actually a PCI ID belonging to realtech. No response was received
  to earlier attempts to notify them of this.
  The manufacturers of some devices have replied to say they will not fix
  this incorrect ID. Add the ID and hope it isn't a problem.
bosch,bmi323
- Add BOSC0200 ACPI ID. Note this is a duplicate of one in the bmc150
  driver (it appears these parts share a windows driver).
  Both drivers perform an ID check that is safe on the other part before
  successfully probing.
hid-sensors-als
- Add color temperature and chromaticity support. Note this is a replacement
  for the series reverted in 6.8 that correctly handles all the potential
  channel combinations.
honeywell,hsc030pa
- Triggered buffer support (after driver cleanup).
honeywell,mprls00025pa
- Improved error handling.
- New DT binding to allow use of part number triplet as provided in data sheet
  to specify equivalent of most of the binding more efficiently.
- SPI support.
memsic,mxc4005
- ACPI ID MDA6655 as seen in the Chuwi Minibook X 2023
ti,hdc3020
- Add threshold event support (after some driver cleanup)
veml,vcnl4000
- Switch to high resolution proximity measurement.

Cleanup
=======
Various minor typo fixes and better use of defines etc.

Treewide
- Stop using ACPI_PTR(). The savings in space are small and not worth
  the complexity of __maybe_unused of ifdef guards.  To avoid use in
  new IIO drivers based on copy and paste, clean it out.
- cleanup.h based handling of iio_device_claim_direct_mode()/
  iio_device_release_direct_mode() using scope_cond_guard().
  In many drivers this is combined with other automated cleanup
  to give maximum simplifications.
  An initial set of drivers are converted over to this infrastructure.

Tools
- Use rewinddir() instead of seekdir() to return to start of file.

core
- Make iio_bus_type constant.

adi,ad16475
- Use irq_get_trigger_type() instead of opencoding.
adi,ad16480
- Use irq_get_trigger_type() instead of opencoding.
adi,ad-sigma-delta
- Avoid overwriting IRQ flags if provided by firmware.
ams,as73211
- Use IIO_VAL_FRACTIONAL for scales to simplify the code and potentially
  improve accuracy.
gts-library
- Use a div64_u64() instead of a loop to do a division.
honeywell,mprls00025pa
- Clean up dt-binding doc.
- Drop defaults when DT binding not providing values. Very unlikely
  these were useful given they were wrong for vast majority of supported
  devices.
- Whitespace cleanup
miramems,da280
- Use i2c_get_match_data() to replace hand rolled ACPI matching code.
semtech,sx9324
- Avoid unnecessary copying of property strings.
st,lsm6dsx
- Improve docs, particularly wrt to making addition of new device
  support less noisy.
st,lsm9ds0
- Use dev_err_probe() in all probe() error handling.
- Improved header includes.
- Tidy up termination of ID tables.
ti,ads1014
- Correct upper bound on PGA (wrong value had no actual impact)
ti,afe4403/4404
- devm_ useage to simplify error handling in probe() and allow() remove to
  be dropped.
voltage-divider
- Add dt-binding for io-channel-cells to allow such a device to be both
  an IIO consumer and IIO producer at the same time.

Adds the ACPI match table for ASUS ROG ALLY to load the bmi323
driver with an ACPI match of "BOSC0200", and a comment about duplicate
ACPI identifiers between devices using the bmc150 and bmi323 chips.
