   4 Subject: [PATCH] media: ov5647: change defaults to better match raw
   5  camera applications.
   6
   7 Specifically:
   8
   9 * AWB is now off by default.
  10
  11 * AEC/AGC is also off by default.
  12
  13 * The default mode is changed to the 10-bit 2x2 binned mode.
  14
  15 AWB and AEC/AGC can be re-enabled using the usual V4L2 controls. The
  16 original 8-bit mode will be respected if an application requests the
  17 8-bit format.
