2018-11-16iio/hid-sensors: Fix IIO_CHAN_INFO_RAW returning wrong values for signed numbersHans de Goede
Before this commit sensor_hub_input_attr_get_raw_value() failed to take the signedness of 16 and 8 bit values into account, returning e.g. 65436 instead of -100 for the z-axis reading of an accelerometer. This commit adds a new is_signed parameter to the function and makes all callers pass the appropriate value for this. While at it, this commit also fixes up some neighboring lines where statements were needlessly split over 2 lines to improve readability.

2017-08-22iio:humidity: drop assign iio_info.driver_module and iio_trigger_ops.ownerJonathan Cameron
The equivalent of both of these are now done via macro magic when the relevant register calls are made. The actual structure elements will shortly go away. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Lars-Peter Clausen <lars@metafoo.de>
2017-03-25iio: hid: Add humidity sensor supportSong Hongyan
Environmental humidity sensor is a hid defined sensor, it shows raw humidity measurement of air. More information can be found in: http://www.usb.org/developers/hidpage/HUTRR39b.pdf According to IIO ABI definition, humidityrelative data output unit is milli percent. Add the unit convert from percent to milli percent. Signed-off-by: Song Hongyan <hongyan.song@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
