Second set of new device support, cleanups and features for IIO in the 5.4 cycle
Revised pull request to fix up a missing Signed-off-by and roll in a fix in the lsm9ds1 support after I broke it when applying. Revised again because the fix changed a hash meaning a fix that previously followed it now had the wrong fixes tag. A few fixes in here that could have gone a faster path but aren't quite worth the rush for 5.3. New device support * ad7606 - Support thead7606bwhich adds a software controlled mode alongside the pin controlled only approach of the ad7606. Including dt-bindings. * lsm6dsx - Add support for the gyro and accelerometer part of the lsm9ds1 which is a compound device also including a magnetometer (st_sensors driver). Includes bindings and precursor rework of the driver. Features * ad7192 - Add support for low pass filter control. - DT binding docs. Cleanups and minor fixes * MAINTAINERS - Fix a typo in a path. - Add entry for ad7606 * ad5380 - Fix a failure to dereference a pointer before atempting to assign the value. * ad7192 - Drop platform data as not used in mainline and we now have full DT bindings. * ad7606 - YAML conversion for dt-bindings. * adis16240 - Rework write_raw to make it more readable using GENMASK. * adis16460 - Fix and issue with an unsigned variable holding potential negatives. * cros_ec - Fix missing default of calibration vector so that we get 'something' before calibration is complete on a given axis. * hid-sensors - Use int_pow instead of opencoding. * isl29501 - rename dt-binding docs to include renesas inline with other renesas parts and general current convention. * kxcjk1013 - Improve comments on the 'unusual' ACPI ids used to identify which sensor is which in certain laptops. * lsm6dsx - Add one bit to the fifo status masks for a number of parts. - Drop a reserved entry from the sensitivity values to tidy up interface. - Use core conversion macro from G to m/s^2 for lsm9ds1 to make it easier to relate to the datasheet and consistent with other parts supported. * max1027 - Use device managed APIs to avoid manual error handling and cleanup. * rfd77402 - Typo in Kconfig help. * sc27xx - Switch to polling mode from interrupts as interrupt handling typically to slow for very short sleeps. * st-sensors - Fix some missing selects for regmap. * tools - Add a .gitignore containing the binary outputs. -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEEbilms4eEBlKRJoGxVIU0mcT0FogFAl1uyTgRHGppYzIzQGtl cm5lbC5vcmcACgkQVIU0mcT0Foideg//fknN/aM40zRZlClkWx9XqUsByS/3XUAl dZL//5DGh566D8/auBeacQxt6SzOFRpj2XwWI/K8mGJi39y9LFOywOn4dDgOBh3x VWe/1eCNFg9Y1eMCXncYHBtxxobuV3UKEjVtYFtzg210HP/KM6C3fWdPTpmj1zNZ PYSnKGiBGxeJHMCUjN0QweifIRvTy0MLkxPc9CUHcFq0XiMD2enI4TwHYuZ/CNQw oisDPPksbPTW5R547vLEnQe/p16MtoFMX57yehbzKIp6qYBEVR+D5ne5kxct8x80 Ma7YVWLyWTxYF/MwLi3felIniEeyYhgTFVhy2rhZGt6eKDmNFTwTrJG5iTweeHQm 3FJPbZ04lDjE3RhoETGDc2aSqY5/Xy1nnOJcMjZ1twbDxPGmN2/rCP3YxYRmGL/P VCsCZYeQF6cKi7FyFiViqALTPH0k/Ebklol1f/IG8CuFCs8r/m6kKMeSJX3+miHZ gIxA2lX5uj8FIiB1bZxORN76W5PzxLji5IiCPy1KtlBin3E3oWM3nQLXNHpzp2Fw 5A8IyHb/qDoKnO1MlTkprIxdIzKqV4gtWqkY1kTBYyNyreMP/dsiw/lC1rnzWMm/ v7JHuTbO/Ay5gvT58goK7FD77CyvRTvy3bmi7PNkWJyogWpnRTLiPusMDz7FwxK4 Ffrbi7+qijk= =rPVR -----END PGP SIGNATURE----- Merge tag 'iio-for-5.4b-take3' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second set of new device support, cleanups and features for IIO in the 5.4 cycle Revised pull request to fix up a missing Signed-off-by and roll in a fix in the lsm9ds1 support after I broke it when applying.

Analog Devices AD7606 Simultaneous Sampling ADC
|

|

Required properties for the AD7606:
|
||||
|
||||
- compatible: Must be one of
|
||||
* "adi,ad7605-4"
|
||||
* "adi,ad7606-8"
|
||||
* "adi,ad7606-6"
|
||||
* "adi,ad7606-4"
|
||||
* "adi,ad7616"
|
||||
- reg: SPI chip select number for the device
|
||||
- spi-max-frequency: Max SPI frequency to use
|
||||
see: Documentation/devicetree/bindings/spi/spi-bus.txt
|
||||
- spi-cpha: See Documentation/devicetree/bindings/spi/spi-bus.txt
|
||||
- avcc-supply: phandle to the Avcc power supply
|
||||
- interrupts: IRQ line for the ADC
|
||||
see: Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
|
||||
- adi,conversion-start-gpios: must be the device tree identifier of the CONVST pin.
|
||||
This logic input is used to initiate conversions on the analog
|
||||
input channels. As the line is active high, it should be marked
|
||||
GPIO_ACTIVE_HIGH.
|
||||
|
||||
Optional properties:
|
||||
|
||||
- reset-gpios: must be the device tree identifier of the RESET pin. If specified,
|
||||
it will be asserted during driver probe. As the line is active high,
|
||||
it should be marked GPIO_ACTIVE_HIGH.
|
||||
- standby-gpios: must be the device tree identifier of the STBY pin. This pin is used
|
||||
to place the AD7606 into one of two power-down modes, Standby mode or
|
||||
Shutdown mode. As the line is active low, it should be marked
|
||||
GPIO_ACTIVE_LOW.
|
||||
- adi,first-data-gpios: must be the device tree identifier of the FRSTDATA pin.
|
||||
The FRSTDATA output indicates when the first channel, V1, is
|
||||
being read back on either the parallel, byte or serial interface.
|
||||
As the line is active high, it should be marked GPIO_ACTIVE_HIGH.
|
||||
- adi,range-gpios: must be the device tree identifier of the RANGE pin. The polarity on
|
||||
this pin determines the input range of the analog input channels. If
|
||||
this pin is tied to a logic high, the analog input range is ±10V for
|
||||
all channels. If this pin is tied to a logic low, the analog input range
|
||||
is ±5V for all channels. As the line is active high, it should be marked
|
||||
GPIO_ACTIVE_HIGH.
|
||||
- adi,oversampling-ratio-gpios: must be the device tree identifier of the over-sampling
|
||||
mode pins. As the line is active high, it should be marked
|
||||
GPIO_ACTIVE_HIGH.
|
||||
|
||||
