1st set of IIO new device support, features and cleanups for the 6.4 cycle.
New device support
* bosch,bmp280
- Add support for BMP580 - includes significant refactoring and general
driver cleanup + support for non-volatile memory for trimming and config
parameters.
* rohm BU27034
- New driver for this 3 channel ambient light sensor.
- New support library for devices where both integration time and
amplifier gain are configurable. In these cases a scale change
may require changing bother underlying values. This library module
provides code to help with this.
* st,accel
- Add support for IIS328DQ (ID only as compatible wtih LIS331DL)
* st,lsm6dsx
- Add support for ASM330LHB automotive MEMS sensor.
* ti,ads1100, ads1000
- New driver for these 16 bit ADCs.
* ti,tmp117
- Add support for older tmp116 device. Includes some general driver cleanup.
Staging driver drops
* adi,ade7854
- Driver was a very long way from compliant with IIO infrastructure and ABI.
If anyone wants a non staging version of this driver they are better off
starting from scratch. Hence drop it and the associated meter.h header.
Features
* adi,ad7441r
- Add DT binding to set sink current for digital input.
* semtech,sx9324,9360
- Support older register mapping from firmware designed for windows.
Core improvements.
* Move iio_trigger_poll() docs to next to the implementation and add a note
on expected caller context.
* Rename iio_trigger_poll_chained() to iio_trigger_poll_nested() so
as to use more standard / common terminology.
* Improve main ABI docs references to offset and scale for raw values by
making them consistent and clear.
Cleanups and minor fixes:
* adi,ad5592r
- Add GPIO names - useful for debug.
* adi,ad7441r
- Fix current input, loop powered mode configuration setup.
* adi,adis16475
- Fix wrong commented value for minimum advised lower rate.
* adi,admv1013
- Use devm_clk_get_enabled() to reduce boilerplate.
* adi,ads1210
- Fix wrong bits for writing config register (late fix and has
been broken a long time so not rushed upstream)
* amlogic,meson-saradc
- Improve cleanup in error handling if BL30 handshake fails.
* apex-embedded,stx104
- Migrate to regmap and use regmap_read_poll_timeout() to neatly handle
retries.
- Add local mutex to close various races.
- Use define U16_MAX rather than value for limit.
- Improve code readability with minor reorganization.
* atmel,ad91-sama5d2
- Drop trivial dead code.
* kionix,kx022a
- Drop unused structure element.
* linear,ltc2983
- Reorganize bindings doc to enable unevaluatedProperties to be set
in one place for all child nodes.
- Make binding for adi,custom-thermocouple accept signed values.
* maxim,max44000
- Add OF Device matching (of_match_table was not correctly set).
* maxim,max5522
- Missing static
* measurement-computing,cio-dac
- Fix wrong part name in comments.
- Migrate to regmap.
- Improve includes by replacing bitops.h with more direct bits.h
* qcom,pm8xxx-xoadc
- Remove a check that can never fail.
* renesas,rcar-gyroadc
- DT binding documentation improvements.
- Tidy up an unused warning with __maybe_unused.
* semtech,sx_common
- Drop docs for a structure element that doesn't exist.
* semtech,sx9500
- Drop ACPI_PTR() and of_match_ptr() protections that just complicate
the code / block some firmware registration types that would otherwise
work.
* sensiron,sps30
- Comment formatting tidy up.
* st,sensors
- Drop duplicate text in DT binding.
* st,stm32-adc
- Add some missing static markings.
* ti,ads1100
- Use correct return code in dev_err_probe() call.
* x-powers,axp20x_adc - precursor series to simplify addition of AXP192.
- General code cleanup / minor refactoring for better readabilty of code.
- Switch from boolean value to mask for adc_en2 field to avoid hard coding
a mask that will be different in AXP192
