Subject: [RFC PATCH v2 0/2] drm/dsi-mipi: 16-bit Brightness Endianness Fix

Changes since v1:
 - move 16-bit brightness handling to new functions and revert API
   change (1/2)
 - remove Change-Id in compliance with checkpatch.pl (1/2)
 - separate panel driver changes (2/2)

This series adds proper support for 16-bit MIPI DSI brightness and
cleans up existing panel drivers.

I cannot test the SOFEF00 change, although I tested an equivalent change
to an external S6E3FA7 driver generated with the same generator. Both
setting and getting works on S6E3FA7.

  drm/panel: sofef00: Use 16-bit panel brightness
