From aab5d5842d718544ef906dc8cc5c221e6121160f Mon Sep 17 00:00:00 2001
From: David Plowman <david.plowman@raspberrypi.com>

Subject: [PATCH] media: ov5647: change defaults to better match raw
camera applications.
Specifically:
* AWB is now off by default.
* AEC/AGC is also off by default.
* The default mode is changed to the 10-bit 2x2 binned mode.
AWB and AEC/AGC can be re-enabled using the usual V4L2 controls. The
original 8-bit mode will be respected if an application requests the
8-bit format.
