Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI panel.
V9: - Adjust init code, make the format more concise - kill off default_off_cmds (Emil) - use mipi_dsi_dcs_set_display_{on,off} in their enable/disable callbacks. (Emil) - Adjusting the delay function (Emil)
V8: - modify PARENTHESIS_ALIGNMENT format (Sam) - use gpios are required API replace optional gpio API (Emil)
V7: - Modify communication address
V6: - Add the information of the reviewer - Remove unnecessary delays, The udelay_range code gracefully returns without hitting the scheduler on a delay of 0. (Derek) - Merge the same data structures, like display_mode and off_cmds (Derek) - Optimize the processing of results returned by devm_gpiod_get_optional (Derek)
V5: - Add the information of the reviewer (Sam) - Delete unnecessary header files #include <linux/fb.h> (Sam) - The config DRM_PANEL_BOE_HIMAX8279D appears twice. Drop one of them (Sam) - ADD static, set_gpios function is not used outside this module (Sam)
V4: - Frefix all function maes with boe_ (Sam) - Fsed "enable_gpio" replace "reset_gpio", Make it look clearer (Sam) - Sort include lines alphabetically (Sam) - Fixed entries in the makefile must be sorted alphabetically (Sam) - Add send_mipi_cmds function to avoid duplicating the code (Sam) - Add the necessary delay(reset_delay_t5) between reset and sending the initialization command (Rock wang)
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.
