First set of IIO new device and feature support for the 5.16 cycle
Counter subsystem changes now sent separately.
This has been a busy cycle, so lots here and a few more stragglers to
come next week.
Big new feature in this cycle is probably output buffer support.
This has been in the works for a very long time so it's great to see
Mihail pick up the challenge and build upon his predecessors work to finally
bring this feature to mainline.
New device support
------------------
* adi,adxl313
- New driver and dt bindings for this low power accelerometer.
* adi,adxl355
- New driver and dt bindings for this accelerometer.
- Later series adds buffer support.
* asahi-kasei,ak8975
- Minor additions to driver to support ak09916
* aspeed,aspeed-adc
- Substantial rework plus feature additions to add support for the
ast2600 including a new dt bindings doc.
* atmel,at91_sama5d2
- Rework and support introduced for the sama7g5 parts.
* maxim,max31865
- New driver and bindings for this RTD temperature sensor chip.
* nxp,imx8qxp
- New driver and bindings for the ADC found on the i.MX 8QuadXPlus Soc.
* senseair,sunrise
- New driver and bindings for this family of carbon dioxide gas sensors.
* sensiron,scd4x
- New driver and bindings for this carbon dioxide gas sensor.
New features
------------
* Output buffer support. Works in a similar fashion to input buffers, but
in this case userspace pushes data into the kfifo which is then drained
to the device when a trigger occurs. Support added to the ad5766 DAC
driver.
* Core, devm_iio_map_array_register() to avoid need for
devm_add_action_or_reset() based cleanup in fully managed allocation
drivers.
* Core iio_push_to_buffers_with_ts_unaligned() function to safely handle a
few drivers where it really hard to ensure the correct data alignment in
an iio_push_to_buffers_with_timestamp() call. Note this uses a bounce
buffer so should be avoided whenever possible. Used in the ti,adc108s102,
invense,mpu3050 and adi,adis16400. This closes the last known set
of drivers with alignment issues at this interface.
* maxim,max1027
- Substantial rework to this driver main target of which was supporting
use of other triggers than it's own EOC interrupt.
- Transfer optimization.
* nxp,fxls8962af
- Threshold even support including using it as a wakeup source.
Cleanups, minor fixes etc
-------------------------
Chances of a common type to multiple drivers:
* devm_ conversion and drop of .remove() callbacks in:
- adi,ad5064
- adi,ad7291
- adi,ad7303
- adi,ad7746
- adi,ad9832
- adi,adis16080
- dialog,da9150-gpadc
- intel,mrfld_adc
- marvell,berlin2
- maxim,max1363
- maxim,max44000
- nuvoton,nau7802
- st_sensors (includes a lot of rework!)
- ti,ads8344
- ti,lp8788
* devm_platform_ioremap_resource() used to reduce boilerplate
- cirrus,ep93xx
- rockchip,saradc
- stm,stm32-dac
* Use dev_err_probe() in more places to both not print on deferred probe and
ensure a reason for the deferral is available for debug purposes.
- adi,ad8801
- capella,cm36651
- linear,ltc1660
- maxim,ds4424
- maxim,max5821
- microchip,mcp4922
- nxp,lpc18xx
- onnn,noa1305
- st,lsm9ds0
- st,st_sensors
- st,stm32-dac
- ti,afe4403
- ti,afe4404
- ti,dac7311
* Drop error returns in SPI and I2C remove() functions as they are ignored and
long term plan is to change these all over to returning void. In some cases
these patches just make it 'obvious' they always return 0 where it was the
case before but not easy to tell.
- adi,ad5380
- adi,ad5446
- adi,ad5686
- adi,ad5592r
- bosch,bma400
- bosch,bmc150
- fsl,mma7455
- honeywell,hmc5843
- kionix,kxsd9
- maxim,max5487
- meas,ms5611
- ti,afe4403
Driver specific changes
* adi,ad5770r
- Bring driver inline with documented bindings.
* adi,ad7746
- Trivial style fix
* adi,ad7949
- Express some magic values as the underlying parts via new #defines.
- Make it work with SPI controllers that don't support 14 or 16 bit messages
- Support selection of voltage reference from dt including expanding the
dt-bindings to cover this new functionality.
* adi,ad799x
- Implement selection of external reference voltage on AD7991, AD7995 and
AD7999.
- Add missing dt-bindings doc for devices supported by this driver.
* adi,adislib
- Move interrupt startup to better location in startup flow.
- Handle devices that cannot mask/unmask the drdy pin and must instead mask
at the interrupt controller. Applies to the adis16460 and adis16475 from
which we then drop equivalent code.
* adi,ltc2983
- Add support for optional reset pin.
- Fail to probe if no channels specified in dt binding.
* asahi-kasei,ak8975
- dt-binding additions of missing vid-supply regulator.
* aspeed,aspeed-adc
- Typo fix.
* fsl,mma7660
- Mark acpi_device_id table __maybe_unused to avoid build warning.
* fsl,imx25-gcq
- Avoid initializing regulators that aren't used.
* invensense,mpu3050
- Drop a dead protection against a clash with the old input driver.
* invensense,mpu6050
- Rework code to not use strcpy() and hence avoid possibility of wrong sized
buffers. Note this wasn't a bug, but the new code is a lot more readable.
- Mark acpi_device_id table __maybe_unused to avoid build warning.
* kionix,kxcjk1013
- dt-binding addition to note it supports interrupts.
* marvell,berlin2-adc
- Enable COMPILE_TEST building.
* maxim,max1027
- Avoid returning success in an error path.
* nxp,imx8qxp
- Fix warning when runtime pm not enabled via __maybe_unused.
* ricoh,rn5t618
- Use the new devm_iio_map_array_register() instead of open coding the same.
* samsung,exynos_adc
- Improve kconfig help text.
* st,lsm6dsx
- Move max_fifo_size into the fifo_ops structure where the other configuration
parameters are found.
* st,st_sensors:
- Reorder to ensure we turn the power off after removing userspace interfaces.
* senseair,sunrise
- Add missing I2C dependency.
* ti,twl6030
- Small code tidy up.
