   4 Subject: [PATCH] drivers: media: imx477: Set horizontal binning when disabling
   5  the scaler
   6
   7 The horizontal scaler has been disabled but actually the sensor is not
   8 binning horizontally, resulting in images that are stretched 2x
   9 horizontally (missing the right half of the field of view completely).
  10
  11 Therefore we must additionally set the horizontal binning mode. There
  12 is only marginal change in output quality and noise levels.
