2016-11-05iio: orientation: hid-sensor-rotation: Add PM function (fix non working driver)Song Hongyan1-0/+1
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.

2015-05-17iio: orientation: hid-sensor-rotation: Fix memory leak in probe()Fabio Estevam1-7/+8
'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.

2015-02-23HID: hid-sensor-hub: Extend API for async readsSrinivas Pandruvada1-1/+2
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.

Added an API to allow client drivers to turn ON and OFF sensors for quick read. Added data_read as counting varaible instead of boolean, so that sensor is powered off only when last user released it.

Added usage id processing for device rotation. This uses IIO interfaces for triggered buffer to present data to user mode.This uses HID sensor framework for registering callback events from the sensor hub. Data is exported to user space in the form of quaternion rotation format. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
