Signed-off-by: Paweł Chmiel Reviewed-by: Sam Ravnborg Reviewed-by: Andrzej Hajda --- Changes from v3: - Squash s6e63m0_brightness_set into s6e63m0_set_brightness - In power_on assert reset gpio after regulators, like it was done in vendor sources - In power_off assert reset gpio before regulators, like it was done in vendor sources - Add reviewed by - Match MCS command names (taken from other samsung panels) Changes from v2: - VIDEOMODE_HELPERS is not needed in Kconfig - Added help text to Kconfig - Remove unneeded videomode includes/fields - Add sentinel comment in s6e63m0_of_match struct - Handle errors during registration of backlight device. We shouldn't register panel if we fail to register backlight device - Added Reviewed-by Changes from v1: - Correct order of Kconfig/Makefile entry - Fix SPDX tag, so it matches value of MODULE_LICENSE - Remove inclusion of drmP.h - Fix code formatting - Use DRM_DEV_ERROR/DEBUG - Extract hardcoded values - Remove possibility to change gamma through sysfs, leaving only one gamma table values - Fix reset_gpio handling, so it'll be asserted in power_on and deasserted in power_off. Also do it before turning voltage on. - Disable backlight and enter sleep mode in disable callback. Previously it was done in unprepare - Enable display and backlight in enable callback. Previously it was done in prepare - Hardcode display timings and delays. Previously they were readed from device tree - We're using SPDX, so we don't need to have license body - Use MIPI_DCS_EXIT_SLEEP_MODE and MIPI_DCS_SET_DISPLAY_ON - Rename MAX_GAMMA_LEVEL to NUM_GAMMA_LEVELS - Ommit get_brightness callback - Use backlight_enable/disable API, like it's done in other panel drivers (for example panel-simple) - Make set_brightness called only from backlight api, like it's done in other panel drivers (for example panel-simple). - Reset gpio should be set to GPIOD_OUT_HIGH.
