Subject: [PATCH v2] media: ov8856: Configure sensor for GRBG Bayer for all modes
Date:   Mon, 11 Jan 2021 12:59:30 +0100

The previously added modes 3264x2448 & 1632x1224 are actually
configuring the sensor for BGGR mode, this is an issue since
the mode that is exposed through V4L incorrectly is set as GRBG.

This patch fixes the issue by configuring the sensor to always
output GRBG Bayer formatted frames.

Changes since v1:
 - Sakari: Added mode information to ov8856_mode struct
 - Sakari: enum_mbus_code updated

Changes since v2:
 - Andrey: Switched approach to changing the sensor configuration
   to yield identical Bayer modes for all modes
