iio: cros_ec: Use Hertz as unit for sampling frequency

2020-03-30T06:24:49Z

To be compliant with other sensors, set and get sensor sampling frequency in Hz, not mHz. Fixes: ae7b02ad2f32 ("iio: common: cros_ec_sensors: Expose cros_ec_sensors frequency range via iio sysfs") Signed-off-by: Gwendal Grignou Acked-by: Jonathan Cameron Signed-off-by: Enric Balletbo i Serra

iio: cros_ec: Report hwfifo_watermark_max

2020-03-28T21:04:33Z

Report the maximum amount of sample the EC can hold. This is not tunable, but can be useful for application to find out the maximum amount of time it can sleep when hwfifo_timeout is set to a large number.

iio: cros_ec: Expose hwfifo_timeout

2020-03-28T21:04:33Z

Expose EC minimal interrupt period through buffer/hwfifo_timeout: - Maximal timeout is limited to 65s. - When timeout for all sensors is set to 0, EC will not send events, even if the sensor sampling rate is greater than 0. Rename frequency to sampling_frequency to match IIO ABI. Signed-off-by: Gwendal Grignou Reviewed-by: Jonathan Cameron Signed-off-by: Enric Balletbo i Serra

iio: cros_ec: Remove pm function

2020-03-28T21:04:32Z

Since cros_ec_sensorhub is shutting down the FIFO when the device suspends, no need to slow down the EC sampling period rate. It was necesseary to do that before command CMD_FIFO_INT_ENABLE was introduced, but now all supported chromebooks have it.

iio: cros_ec: Register to cros_ec_sensorhub when EC supports FIFO

2020-03-28T21:04:32Z

When EC supports FIFO, each IIO device registers a callback, to put samples in the buffer when they arrives from the FIFO. When no FIFO, the user space app needs to call trigger_new, or better register a high precision timer.

iio: cros_ec: Move function description to .c file

iio: st_sensors: handle memory allocation failure to fix null pointer dereference

2020-02-14T12:08:22Z

A null pointer deference on pdata can occur if the allocation of pdata fails. Fix this by adding a null pointer check and handle the -ENOMEM failure in the caller.
