   4 Subject: [PATCH] media: i2c: imx477: Replace existing 1012x760 mode
   5
   6 The existing 1012x760 120 fps mode has significant IQ problem using
   7 the internal sensor scaler. Replace this mode with a 1332x990 120 fps
   8 mode instead. This new mode has a smaller field of view, but does not
   9 suffer from the bad IQ of the original mode.
