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.

The ADXL367 is an ultralow power, 3-axis MEMS accelerometer.
The ADXL367 does not alias input signals to achieve ultralow power
consumption, it samples the full bandwidth of the sensor at all
data rates. Measurement ranges of +-2g, +-4g, and +-8g are available,
with a resolution of 0.25mg/LSB on the +-2 g range.
In addition to its ultralow power consumption, the ADXL367
has many features to enable true system level power reduction.
It includes a deep multimode output FIFO, a built-in micropower
temperature sensor, and an internal ADC for synchronous conversion
of an additional analog input.

BMC156 is another accelerometer that works just fine with the bmc150-accel
driver. It's very similar to BMC150 (also a accelerometer + magnetometer
combo) but with only one accelerometer interrupt pin. It would make sense
if only INT1 was exposed but someone at Bosch decided to only have an
INT2 pin.
Try to deal with this by making use of the INT2 support introduced
in the previous commit and force using INT2 for BMC156. To detect
that we need to bring up a simplified version of the previous type IDs.
Note that unlike the type IDs removed in commit c06a6aba6835
("iio: accel: bmc150: Drop misleading/duplicate chip identifiers")
here I only add one for the special case of BMC156. Everything else
still happens by reading the CHIP_ID register since the chip type
information often is not accurate in ACPI tables.

Commit c1d1c4a62db5 ("iio: accel: bma180: BMA254 support") added
BMA254 support to the bma180 driver and changed some naming to BMA25x
to make it easier to add support for BMA253 and BMA255.
Unfortunately, there is quite some overlap between the bma180 driver
and the bmc150-accel driver. Back when the commit was made, the
bmc150-accel driver actually already had support for BMA255, and
adding support for BMA254 would have been as simple as adding a new
compatible to bmc150-accel.
The bmc150-accel driver is a bit better for BMA254 since it also
supports the motion trigger/interrupt functionality. Fortunately,
moving BMA254 support over to bmc150-accel is fairly simple because
the drivers have compatible device tree bindings.
Revert most of the changes for BMA254 support in bma180 and move
BMA254 over to bmc150-accel. This has the following advantages:
- Support for motion trigger/interrupt
- Fix incorrect scale values (BMA254 currently uses the same as
BMA250 but actually they're different because of 10 vs 12 bits
data size)
- Less code than before :)
BMA250 could be potentially also moved but it's more complicated
because its chip_id conflicts with the one for BMA222 in bmc150-accel.
Perhaps there are also other register differences, I did not investigate
further yet (and I have no way to test it).

The Kconfig option currently says that all Bosch accelerometers
supported by the bmc150-accel driver are combo chips with both
accelerometer and magnetometer. This is wrong: actually only BMC150
is such a combo. The BMA* variants only contain an accelerometer
and the BMI055 actually is a accelerometer + gyroscope combo.

During commit 067fda1c065ff ("iio: hid-sensors: move triggered buffer
setup into hid_sensor_setup_trigger"), the
iio_triggered_buffer_{setup,cleanup}() functions got moved under the
hid-sensor-trigger module.
The above change works fine, if any of the sensors get built. However, when
only the common hid-sensor-trigger module gets built (and none of the
drivers), then the IIO_TRIGGERED_BUFFER symbol isn't selected/enforced.
Previously, each driver would enforce/select the IIO_TRIGGERED_BUFFER
symbol. With this change the HID_SENSOR_IIO_TRIGGER (for the
hid-sensor-trigger module) will enforce that IIO_TRIGGERED_BUFFER gets
selected.
All HID sensor drivers select the HID_SENSOR_IIO_TRIGGER symbol. So, this
change removes the IIO_TRIGGERED_BUFFER enforcement from each driver.

The bma023 chip is similar enough to the bma180 and bma25x that the
same driver can support all of them. The biggest differences are
the lack of a temperature channel and no low power but still working
mode.
The bma150 is a close relative of the bma023, but it does have a
temperature channel so support is not added for it.

The bma180 IIO driver is being extended for support for the chips
support by input's bma150 driver (bma023, bma150, smb380). Don't
allow both drivers to be enabled simultaneously as they're for the
same hardware.

This adds support for the BMA254 variant of this
accelerometer. The only difference for the simple IIO
driver is that values are 12 bit and the temperature
offset differs by 1 degree.
Whilst wildcards in naming are normally frowned upon:
The cases where I have labeled variables "25x" is where the
models are identical, so as to make things easier for people
that want to add support for BMA253 and BMA255.

This patch restructures the existing adxl372 driver by adding a module for
SPI and a header file, while the baseline module deals with the chip-logic.
This is a necessary step, as this driver should support in the future
a similar device which differs only in the type of interface used (I2C
instead of SPI).

The only difference is the resolution of the acceleration sensor. The

Add driver to support older EC firmware that only support deprecated
ec command. Rely on ACPI memory map register to access sensor
information.
Present same interface as the regular cros_ec sensor stack:
- one iio device per accelerometer
- use HTML5 axis definition
- use iio abi units
- accept calibration calls, but do nothing
Chrome can use the same code than regular cros_ec sensor stack to
calculate orientation and lid angle.
