Merge tag 'iio-for-5.4a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
First set of new device support, features and cleanups for IIO in the 5.4 cycle
Note includes a merge from i3c tree to get support needed for stm_lsm6dsx driver
support for l3c devices. Done from immutable branch.
A counter subsystem patche in here as well.
Alongside the new device support (which is always good), Chuhong's work
on using devres managed APIs has cleaned up a number of drivers.
New device support
* adis16460
- New driver based on ADIS framework which needed addition of support
for cs_change_delay. Includes device tree binding.
* cros_ec
- Support fo the veyron-minnie which uses an older interface.
* lsm6dsx
- Support for LSM6DSTR-C gyro + magnetometer sensor (new IDs mainly)
- Support for ISM330DHCX acc + gyro sensor (extensive rework needed!)
* Maxim 5432
- New driver support MAX5432-MAX5435 family of potentiometers.
* noa1305
- New driver for this ON Semiconductor Ambient light sensor.
Features and cleanups
* tree wide
- Drop error prints after platform_get_irq as already prints errors
internally if any occur.
* docs
- Document mounting matrix.
- Fix a missing newline at end of file.
* ad2s1210
- Switch to device managed APIs for all of probe and drop explicit remove.
* ad7192
- Add of_device_id array to explicity handling DT bindings.
* ad7606
- Lots of rework leading to support for software configure modes in ad7616
parts.
- Debugfs register access support.
* am2315
- Switch to device managed APIs for all of probe and drop explicit remove.
* apds9960
- Typo in module description.
* cm36651
- Convert to i2c_new_dummy_device.
- Swithc to device managed APIs for all of probe adn drop explicit remove.
* cros_ec
- Calibscale support for accel, gyro and magnetometer.
- Tidy up some error codes to return the error from the stack rather than
-EIO.
- Determine protocol version.
- Add a sign vector to the core to fix sensor rotation if necessary.
Cannot just be done with mount matrix as already in use in many devices.
- Tidy up INFO_SCALE being in both the separate and shared lists.
- Drop a lot of dplicate code from the cros-ec-accel-legacy driver
and use the core provided code instead.
- Make frequency range available to userspace.
* counter / ftm-quaddec
- Switch to device managed APIs for all of probe adn drop explicit remove.
* hdc100x
- Switch to device managed APIs for all of probe and drop explicit remove.
* hi8435
- Use gpiod_set_value_cansleep as we don't care here and there is a
board out there where it needs to sleep.
- Switch to device managed APIs for all of probe and drop explict remove.
* hp03
- Convert to i2c_new_dummy_device.
* maxim thermocouple
- Switch to device managed APIs for all of probe and drop explicit remove.
* mmc35240
- Fix typo in constant naming.
* mpu6050
- Use devm_add_action_or_reset in place of explicit error handling.
- Make text in Kconfig more explicit about which parts are supported.
* mxc4005
- Switch to device managed APIs for all of probe and drop explicit remove.
* pms7003
- Convert device tree bindings to yaml.
- Add a MAINTAINERS entry
* sc27xx
- Introduce a local struct device *dev pointer to avoid lots of deref.
- Use devm_add_action_or_reset in place of explicit error handling.
* sca3000
- Typo fix in naming.
* si1145
- Switch to device managed APIs for all of probe and drop explicit remove.
* st_sensors
- Lots of rework to enable switch to regmap.
- Regmap conversion at the end.
- Tidy up some inconsistencies in buffer setup ops.
- Tidy up an oddity by dropping get_irq_data_ready function in favour
of direct access.
- Stop allocating buffer in buffer enable in favour of just embedding
a large enough constant size buffer in the iio_priv accessed structure.
* st_lsm6dsx
- l3c device support (LSM6DSO and LSM6DSR)
- tidy up irq return logic which was strangely written.
- fix up an ABI quirk where this driver used separate scale
attributes, even though they were always shared by type.
* stk33xx
- Device tree bindings include manufacturer ID.
* stm32-adc
- Add control for supply to analog switches including DT bindings.
* stm32 timer
- Drop the quadrature mode support. Believed there were no users so
take this opportunity to drop this unwanted ABI.
* tsl2772
- Switch to device mangage APIs for all of probe and drop explicit remove.
- Use regulator_bulk_* APIs to reduce repitition.
* veml6070
- Convert to i2c_new_dummy_device.
