From dfa76fa2824967c0ec196fbcba36d3e74b66d3aa Mon Sep 17 00:00:00 2001 From: Adam Baker Date: Sun, 29 Mar 2009 19:17:10 -0300 Subject: V4L/DVB (11387): Sensor orientation reporting Add support to the SQ-905 driver to pass back to user space the sensor orientation information obtained from the camera during init. Modifies gspca and the videodev2.h header to create the necessary API.
