   4 Subject: [PATCH 0813/1085] media: i2c: adv7180: Use MEDIA_BUS_FMT_UYVY8_1X16
   5  for CSI2 output
   6
   7 CSI2 devices are meant to use the 1Xnn formats rather than 2Xnn
   8 such as MEDIA_BUS_FMT_UYVY8_2X8.
   9
  10 For devices with ADV7180_FLAG_MIPI_CSI2 set, use
  11 MEDIA_BUS_FMT_UYVY8_1X16.
