This change replaces indio_dev's mlock with the driver's own lock. The lock is mostly needed to protect state when changing the `dac_cache` info. The lock has been extended to `ad7303_read_raw()`, to make sure that the cache is updated if an SPI-write is already in progress. Signed-off-by:

On LSM6DSO/LSM6DSR/LSM6DSOX/ASM330LHH and ISH330DHCX devices it is possible to trim the hardware timestamp resolution through the FREQ_FINE[7:0] bits of the INTERNAL_FREQ_FINE register, which contains the difference in percentage of the effective ODR (and timestamp rate) with respect to the typical value. The formula for calculating the effective ODR reported in the application notes has been linearized to the first order to simplify the calculation (pls. see note on source code). This change may be useful in the outcome of CTS tests regarding the SingleSensorTests and the SensorTest#testSensorTimeStamps for high ODRs Signed-off-by:

Add support for runtime PM & sleep. Provide pclk to regmap as registers access doesn't need full power (e.g. regulator). Always restore HFSEL when resuming. It may get lost depending on low power level that has been achieved. Signed-off-by:

Miquel Raynal authored
The chips have a 'start conversion' and a 'end of conversion' pair of pins. They can be used but this is absolutely not mandatory as regular polling is supported by the chip depending on its internal clocking setup. There is no physical reason to force the use of interrupts so turn them optional. Also, once the interrupt turned optional, these devices fit perfectly the "trivial devices" described in the generic (yaml) bindings file, so instead of converting this text file to json schema, we can just add the relevant compatibles in: Documentation/devicetree/bindings/trivial-devices.yaml.

Maxim's max12xx series is very similar to the max10xx series, with the difference of the measurements depth which is upgraded from 10 to 12 bits per channel. Everything else looks the same. Signed-off-by:

Maxim's max1027/29/31 series returns the measured voltages with a resolution of 10 bits. There is a very similar series, max1227/29/31 which works identically but uses a resolution of 12 bits. Prepare the support for these chips by turning the 'depth' into a macro parameter instead of hardcoding it everywhere. Also reorganize just a bit the macros at the top to avoid repeating tens of lines when adding support for a new chip. Signed-off-by:

Miquel Raynal authored
The chip has a 'start conversion' and a 'end of conversion' pair of pins. They can be used but this is absolutely not mandatory as regular polling of the value is totally fine with the current internal clocking setup. Turn the interrupts optional and do not error out if they are not inquired in the device tree. This has the effect to prevent triggered buffers use though. Signed-off-by:

Miquel Raynal authored
Until now, only write operations were supported. Force two bytes read operation when reading, which should fit most of the development purposes. Of course, extended operations like buffered reads on multiple channels or even temperature + voltage reads will not be read entirely. Usually, just starting a new operation will work but in any case a software reset (done through the debufs interface too) will return the device in a usable state. Signed-off-by:

Since wfx_tx_get_raw_link_id() return an unsigned, it makes no sense to return a negative value. "15" is a better value since it is used by firmware for stations that have not yet associated link-ids. Note that this should never happens since driver set max_ap_assoc_sta to 14.
