iio:st sensors: remove custom sampling frequence attribute in favour of core support.

2018-12-11T15:03:50+00:00

This allows in kernel client drivers to access this Signed-off-by: Jonathan Cameron Cc: Denis Ciocca Reviewed-by: Hartmut Knaack Signed-off-by: Moyster omitted pressure driver changes (missing in this kernel)

iio:st_sensors: Fix oops when probing SPI devices

2018-12-11T15:02:26+00:00

In SPI mode the transfer buffer is locked with a mutex. However this mutex is only initilized after the probe, but some transfer needs to be done in the probe. To fix this bug we move the mutex initialization at the beginning of the device probe.

iio: st_sensors: announce registered sensors

2018-12-11T14:51:11+00:00

It is pretty helpful to know already from dmesg that a certain device is successfully registered, instead of having to browse sysfs to see if it's actually there.

iio:accel: Register buffer also without specific trigger

2018-12-11T14:51:11+00:00

This patch fix buffer registration that allows to use generic IIO trigger. Signed-off-by: Denis Ciocca Signed-off-by: Jonathan Cameron

iio: accel-core: st: Clean up error handling in probe()

2018-12-11T14:51:11+00:00

Reduce the amount of those unnecessary goto calls, as in most cases we can simply return immediately. We also only call for the IRQ number once and use that value throughout. Signed-off-by: Lee Jones Signed-off-by: Jonathan Cameron

iio: accel: st_accel: Use devm_iio_device_alloc

2018-12-11T14:51:11+00:00

Using devm_iio_device_alloc makes code simpler. Signed-off-by: Sachin Kamat Cc: Denis Ciocca Signed-off-by: Jonathan Cameron

iio: Added ST-sensors platform data to select the DRDY interrupt pin

2018-12-11T14:51:10+00:00

This patch add support to redirect the DRDY interrupt on INT1 or INT2 on accelerometer and pressure sensors. Signed-off-by: Denis Ciocca Signed-off-by: Jonathan Cameron Signed-off-by: Moyster omitted pressure drivers changes (missing on this kernel)

iio:common: Removed stuff macros, added num_data_channels on st_sensors struct and added support on one-shot sysfs reads to 3 byte channel

2018-12-11T14:51:10+00:00

This patch introduce num_data_channels variable on st_sensors struct to manage different type of channels (size or number) in st_sensors_get_buffer_element function. Removed ST_SENSORS_NUMBER_DATA_CHANNELS and ST_SENSORS_BYTE_FOR_CHANNEL and used struct iio_chan_spec const *ch to catch data. Added 3 byte channel data support on one-shot reads.

iio: accel: kxsd9: Fix scaling bug

2017-04-11T08:58:27+00:00

commit 307fe9dd11ae44d4f8881ee449a7cbac36e1f5de upstream. All the scaling of the KXSD9 involves multiplication with a fraction number < 1. However the scaling value returned from IIO_INFO_SCALE was unpredictable as only the micros of the value was assigned, and not the integer part, resulting in scaling like this: $cat in_accel_scale -1057462640.011978 Fix this by assigning zero to the integer part.
