Commit 33ec3e5f ("iio: adc: adding support for MCP3564 ADC") adds a new iio driver and corresponding MAINTAINERS section. It however uses spaces instead of a single tab for all the entries in that MAINTAINERS section. Although, the get_maintainer.pl script handles spaces instead of tabs silently, the MAINTAINERS will quickly get into a messy state with different indentations throughout the file. So, the checkpatch.pl script complains when spaces instead of a single tab are used. Fix this recently added section using tabs instead of spaces. Further, add the driver's ABI documentation file to this section as well. Fixes: 33ec3e5f ("iio: adc: adding support for MCP3564 ADC") Signed-off-by:

When IIO goes through the available scan masks in order to select the best suiting one, it will just accept the first listed subset of channels which meets the user's requirements. If driver lists a mask which is a subset of some of the masks previously in the array of avaliable_scan_masks, then the latter one will never be selected. Add a warning if driver registers masks which can't be used due to the available_scan_masks-array ordering. Suggested-by:

The adis16460 device requires a stall time between SPI transactions (during which the chip select is inactive), with a minimum value equal to 16 microseconds. This commit adds 'spi-cs-inactive-delay-ns' property, which should indicate the stall time between consecutive SPI transactions. The specified minimum time may not be sufficient for all configurations. Signed-off-by:

A delay is needed each time the chip selected becomes inactive, even after burst data readings are performed. Currently, there is no delay added after a burst reading and in case a new SPI transfer is performed before the needed delay, the adis device becomes unresponsive until reset. This commit is adding the needed delay directly to the spi driver, using the cs_inactive parameter, in case it is not set and is removing the additional chip select change delay present in adis APIs to remove the double delay.

Commit b512c767e7bc ("iio: imu: Add driver for BMI323 IMU") adds the MAINTAINERS section BOSCH SENSORTEC BMI323 IMU IIO DRIVER and refers to a non-existing device-tree file. Probably, this mistake was introduced by copying from the BOSCH SENSORTEC BMA400 ACCELEROMETER IIO DRIVER section and missing to adjust the file entry properly. This is however easily caught, as the script ./scripts/get_maintainer.pl --self-test=patterns complains about a broken reference. The related commit 77583938740e ("dt-bindings: iio: imu: Add Bosch BMI323") adds bosch,bmi323.yaml, so refer to that intended file instead. Signed-off-by: -

The RGB + IR data can be used to calculate the illuminance value (luxes). Implement the equation obtained from the ROHM HW colleagues and add a raw light data channel outputting illuminance values in (nano) Luxes. Both the read_raw and buffering values are supported, with the limitation that buffering is only allowed when a suitable scan-mask is used. (RGB+IR, no clear). The equation has been developed by ROHM HW colleagues for open air sensor. Adding any lens to the sensor is likely to impact to used c1, c2, c3 coefficients. Also, the output values have only been tested on BU27008. According to the HW colleagues, the very same equation should work on BU27010 as well. Calculate and output illuminance values from BU27008 and BU27010. Signed-off-by:

It is possible to use the AD2S1210 with hardwired mode pins (A0 and A1). According to the devicetree bindings, in this case the adi,fixed-mode property will specify which of the 3 possible modes the mode pins are hardwired for and the gpio-modes property is not allowed. This adds support for the case where the mode pins are hardwired for config mode. In this configuration, the position and value must be read from the config register. The case of hardwired position or velocity mode is not supported as there would be no way to configure the device. Signed-off-by:

The MAX34408/MAX34409 are two- and four-channel current monitors that are configured and monitored with a standard I2C/SMBus serial interface. Each unidirectional current sensor offers precision high-side operation with a low full-scale sense voltage. The devices automatically sequence through two or four channels and collect the current-sense samples and average them to reduce the effect of impulse noise. The raw ADC samples are compared to user-programmable digital thresholds to indicate overcurrent conditions. Overcurrent conditions trigger a hardware output to provide an immediate indication to shut down any necessary external circuitry. Add as ADC driver which only supports current monitoring for now.
