+Subject: [PATCH] media: i2c: Add driver for Sony IMX477 sensor
+
+Adds a driver for the 12MPix Sony IMX477 CSI2 sensor.
+Whilst the sensor supports 2 or 4 CSI2 data lanes, this driver
+currently only supports 2 lanes.
+
+The following Bayer modes are currently available:
+
+4056x3040 12-bit @ 10fps
+2028x1520 12-bit (binned) @ 40fps
+2028x1050 12-bit (cropped/binned) @ 50fps
+1012x760 10-bit (scaled) @ 120 fps
