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.

2017-07-17iio: orientation: hid-sensor-rotation: Drop unnecessary staticJulia Lawall
Drop static on a local variable, when the variable is initialized before any possible use. Thus, the static has no benefit. The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @bad exists@ position p; identifier x; type T; @@ static T x@p; ... x = <+...x...+> @@ identifier x; expression e; type T; position p != bad.p; @@ -static T x@p; ... when != x when strict ?x = e; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

2017-05-07iio: hid-sensor-rotation: Add geomagnetic orientation sensor hid support.Song Hongyan
Geomagnetic orientation(AM) sensor is one kind of orientation 6dof sensor. It gives the device rotation in respect to the earth center and the magnetic north. The sensor is implemented through use of an accelerometer and magnetometer do not use gyroscope. It is a standard HID sensor. More information can be found in: http://www.usb.org/developers/hidpage/HUTRR59_-_Usages_for_Wearables.pdf Geomagnetic orientation(AM) sensor and dev rotation sensor have same channel and share channel usage id. So the most of the code for relative orientation sensor can be reused. Signed-off-by: Song Hongyan <hongyan.song@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

Relative orientation(AG) sensor is a 6dof orientation sensor, it depends on acceleration and gyroscope sensor data.

2016-11-05iio: orientation: hid-sensor-rotation: Add PM function (fix non working driver)Song Hongyan
This fix makes newer ISH hubs work. Previous ones worked by lucky coincidence. Rotation sensor function does not work due to miss PM function. Add common hid sensor iio pm function for rotation sensor. Further clarification from Srinivas: If CONFIG_PM is not defined, then this prevents this sensor to function. So above commit caused this. This sensor was supposed to be always on to trigger wake up in prior external hubs. But with the new ISH hub this is not the case.
