- Remove unnecessary delays in sending initialization commands (Jitao Shi)
V2:
- Use SPDX identifier (Sam)
- Use necessary header files replace drmP.h (Sam)
- Delete unnecessary header files #include <linux/err.h> (Sam)
- Specifies a GPIOs array to control the reset timing,
instead of reading "dsi-reset-sequence" data from DTS (Sam)
- Delete backlight_disable() function when already disabled (Sam)
- Use devm_of_find_backlight() replace of_find_backlight_by_node() (Sam)
- Move the necessary data in the DTS to the current file,
like porch, display_mode and Init code etc. (Sam)
- Add compatible device "boe,himax8279d10p" (Sam)
