From 6b3c057ec5705d3c7556d4755103a2650d3aaaf5 Mon Sep 17 00:00:00 2001
From: Dave Stevenson <dsteve@broadcom.com>
Date: Wed, 12 Feb 2014 11:18:20 +0000
Subject: [PATCH 169/174] V4L2: H264 profile & level ctrls, FPS control and
 auto exp pri

Several control handling updates.
H264 profile and level controls.
Timeperframe/FPS reworked to add V4L2_CID_EXPOSURE_AUTO_PRIORITY to
select whether AE is allowed to override the framerate specified.
