Various 2-in-1's use KIOX010A and KIOX020A as HIDs for 2 KXCJ91008
accelerometers. The KIOX010A HID is for the one in the base and the
KIOX020A for the accelerometer in the keyboard.
Since userspace does not have a way yet to deal with (or ignore) the

iio: adc: meson-saradc: fix internal clock names
Before this patch we are registering the internal clocks (for example on
Meson8b, where the SAR ADC IP block implements the divider and gate
clocks) with the following names:
- /soc/cbus@
c1100000/adc@8680#adc_div
- /soc/cbus@
c1100000/adc@8680#adc_en
This is bad because the common clock framework uses the clock to create
a directory in <debugfs>/clk. With such name, the directory creation
(silently) fails and the debugfs entry ends up being created at the
debugfs root.
With this change, the new clock names are:
-
c1108680.adc#adc_div
-
c1108680.adc#adc_en
This matches the clock naming scheme used in the PWM, Ethernet and MMC
drivers. It also fixes the problem with debugfs.
The idea is shamelessly taken from commit
b96e9eb62841c5 ("pwm: meson:
Fix mux clock names").

Cleanups and minor fixes
* tools
- Allow outside specification of CFLAGS
* ad2s90
- Handle and spi_read error.
- Handle spi_setup failure
- Drop a pointless assignment.
- Prevent a potentail race by moving device registration to after
all other setup.
- Add missing scale attribute.
- Add a sanity check on channel type before trying to read it.
* ad2s1210
- Move to modern gpio descriptors.
- Drop a gpioin flag which made no sense as far as we can tell.
- Add dt table (bindings doc to follow when this is ready for
moving out of staging).
* ad5933
- Drop camel-case naming of ext_clk_hz.
- White space fixes.
* ad7150
- Local variable to shorten overly long line.
- Alignment and line break fixes.
*
ad7280a
- Handle an error path that was previously ignored.
- Use crc8.h to build the crc table replacing custom code.
- Avoid unecessary cast.
- Power down the device if an error happens in probe
- Use devm routines to simplify probe and remove.
* ad7606
- Alignment fixes.
* ad7780
- This worked as long as by coincidence an uninitialized value
was 0. Lets not rely on that.
- Ensure gain update is only used with the ad778x chips that
actually support it.
- Tidy up pattern mask generation.
- Read regulator when scale is requested (which should be infrequent)
as it might have changed from initialization.
* ad7816
- Move to modern gpio descriptors
- Don't use a busy_pin for ad7818 as there isn't one.
- Ensure RD/WR and CONVST pins are outputs (previously they
were brought up as inputs which doesn't seem to make any sense)
- DT id table.
* adc128s052
- SPDX
* adt7316
- Alignment fix.
- Fix data reading. When using I2C the driver never actually
used the value read. This has been broken a very long time
hence no rush to fix it now + the driver is undergoing a lot
of cleanup.
- Sanity check that the i2c read didn't fail to actually read
anything.
* dpot-dac
- Mark a switch full through with slightly different text so that
gcc doesn't warn on it.
* gyro-adc
- Fix a wrong file in the MAINTAINERS entry and add binding doc to the
listed files.
* ina2xx
- Add some early returns to clarify error paths in switch.
* lsm6dsx
- MAINTAINERS entry.
* max11100

- Add ADC conversion timeout support to avoid possible fault.
* ssp_sensors
- Don't free managed resources manually.
* st-magn
- Add a comment to avoid future confusion over when to use -magn
postfix (on multi chip in package parts)
- Add BDU register for LIS3MDL where it seems to have been missed.
* st-sensors
- Minor spelling, grammar etc fixes.
* tpl0102

The ad7124-4 and ad7124-8 are a family of 4 and 8 channel sigma-delta ADCs
with 24-bit precision and reference.
Three power modes are available which in turn affect the output data rate:
* Full power: 9.38 SPS to 19,200 SPS
* Mid power: 2.34 SPS to 4800 SPS
* Low power: 1.17 SPS to 2400 SPS
The ad7124-4 can be configured to have four differential inputs, while
ad7124-8 can have 8. Moreover, ad7124 also supports per channel
configuration. Each configuration consists of gain, reference source,
output data rate and bipolar/unipolar configuration.
