Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI panel.
V3: - 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)
V1: - Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI panel.
