iio: hid-sensor-rotation: Add "scale" and "offset" properties parse support

2017-05-07T11:22:36Z

Add orientation sensor "scale" and "offset" parse support. These two properties are needed for exponent data conversion. Signed-off-by: Song Hongyan Reviewed-by: Andy Shevchenko Reviewed-by: Xu Even Acked-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron

iio: hid-sensor-rotation: Add geomagnetic orientation sensor hid support.

2017-05-07T11:22:33Z

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 Signed-off-by: Jonathan Cameron

iio: hid-sensor-rotation: Add relative orientation sensor hid support

2017-05-07T11:22:27Z

Relative orientation(AG) sensor is a 6dof orientation sensor, it depends on acceleration and gyroscope sensor data. It gives a quaternion describing the orientation of the device relative to an initial orientation. It is a standard HID sensor. More information can be found in: http://www.usb.org/developers/hidpage/HUTRR59_-_Usages_for_Wearables.pdf Relative orientation(AG) sensor and dev rotation sensor have same channels and share channel usage id.

iio: orientation: hid-sensor-rotation: Add PM function (fix non working driver)

2016-11-05T17:47:47Z

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.

iio: orientation: hid-sensor-rotation: Fix memory leak in probe()

2015-05-17T08:10:25Z

'channels' is allocated via kmemdup and it is never freed in the subsequent error paths. Use 'indio_dev->channels' directly instead, so that we avoid such memory leak problem. Signed-off-by: Fabio Estevam Reviewed-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron

HID: hid-sensor-hub: Extend API for async reads

2015-02-23T14:16:37Z

Add additional flag to read in async mode. In this mode the caller will get reply via registered callback for capture_sample. Callbacks can be registered using sensor_hub_register_callback function. The usage id parameter of the capture_sample can be matched with the usage id of the requested attribute. Signed-off-by: Srinivas Pandruvada Acked-by: Jonathan Cameron Signed-off-by: Jiri Kosina
