From b3f4737d00de317d1549d5cb5b1dad90e19f5cec Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Thu, 19 Feb 2015 15:33:56 -0800 Subject: HID: hid-sensor-hub: Extend API for async reads 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.
