Subject: [RFC PATCH v3 0/3] drm/mipi-dsi: 16-bit Brightness Endianness Fix
Date:   Mon, 16 Jan 2023 17:49:06 -0500
Message-Id: <20230116224909.23884-1-mailingradian@gmail.com>

Changes since v2 (20230114010006.50471-1-mailingradian@gmail.com):
 - patch vtdr6130 to use _large (3/3)
 - remove Change-Id again (1/3)
 - change patch subject (1-2/3)
 - correct function name in patch description (2/3)
 - add Tested-by tags (1-2/3)

Changes since v1 (20230113041848.200704-1-mailingradian@gmail.com):
 - 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 with 16-bit brightness.

Both setting and getting works on an external S6E3FA7
(max_brightness = 1023) panel driver with the first patch.

Even though this originally fixed both 8-bit and 16-bit brightness, the
8-bit fix is omitted for now because it affects ~13 panels that would
need to be tested:

    panel-asus-z00t-tm5p5-n35596.c
    panel-boe-bf060y8m-aj0.c
    panel-dsi-cm.c
    panel-ebbg-ft8719.c
    panel-jdi-fhd-r63452.c
    panel-jdi-lt070me05000.c
    panel-novatek-nt35510.c
    panel-novatek-nt35560.c
    panel-orisetech-otm8009a.c
    panel-raydium-rm67191.c
    panel-samsung-s6e63j0x03.c
    panel-sony-acx565akm.c
    panel-sony-tulip-truly-nt35521.c
