It's based on already removed, non dt s6e63m0 driver and panel-samsung-ld9040. It can be found for example in some of Samsung Aries based phones. Signed-off-by: Paweł Chmiel Reviewed-by: Sam Ravnborg Reviewed-by: Andrzej Hajda --- 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. It's declared as active low in device tree - Don't call power_off in remove callback --- drivers/gpu/drm/panel/Kconfig | 9 + drivers/gpu/drm/panel/Makefile | 1 + drivers/gpu/drm/panel/panel-samsung-s6e63m0.c | 517 ++++++++++++++++++ 3 files changed, 527 insertions(+) create mode 100644 drivers/gpu/drm/panel/panel-samsung-s6e63m0.c diff --git a/drivers/gpu/drm/panel/Kconfig b/drivers/gpu/drm/panel/Kconfig index 3f3537719beb..45e9ab4b7857 100644 --- a/drivers/gpu/drm/panel/Kconfig +++ b/drivers/gpu/drm/panel/Kconfig @@ -158,6 +158,15 @@ config DRM_PANEL_SAMSUNG_S6E63J0X03 depends on BACKLIGHT_CLASS_DEVICE select VIDEOMODE_HELPERS +config DRM_PANEL_SAMSUNG_S6E63M0 + tristate "Samsung S6E63M0 RGB/SPI panel" + depends on OF + depends on SPI + depends on BACKLIGHT_CLASS_DEVICE + help + Say Y here if you want to enable support for Samsung s6e63m0 + AMOLED LCD panel. + config DRM_PANEL_SAMSUNG_S6E8AA0 tristate "Samsung S6E8AA0 DSI video mode panel" depends on OF diff --git a/drivers/gpu/drm/panel/Makefile b/drivers/gpu/drm/panel/Makefile index 4396658a7996..4507a2d253ac 100644 --- a/drivers/gpu/drm/panel/Makefile +++ b/drivers/gpu/drm/panel/Makefile @@ -16,6 +16,7 @@ obj-$(CONFIG_DRM_PANEL_SAMSUNG_LD9040) += panel-samsung-ld9040.o obj-$(CONFIG_DRM_PANEL_SAMSUNG_S6D16D0) += panel-samsung-s6d16d0.o obj-$(CONFIG_DRM_PANEL_SAMSUNG_S6E3HA2) += panel-samsung-s6e3ha2.o obj-$(CONFIG_DRM_PANEL_SAMSUNG_S6E63J0X03) += panel-samsung-s6e63j0x03.o +obj-$(CONFIG_DRM_PANEL_SAMSUNG_S6E63M0) += panel-samsung-s6e63m0.o obj-$(CONFIG_DRM_PANEL_SAMSUNG_S6E8AA0) += panel-samsung-s6e8aa0.o obj-$(CONFIG_DRM_PANEL_SEIKO_43WVF1G) += panel-seiko-43wvf1g.o obj-$(CONFIG_DRM_PANEL_SHARP_LQ101R1SX01) += panel-sharp-lq101r1sx01.o diff --git a/drivers/gpu/drm/panel/panel-samsung-s6e63m0.c b/drivers/gpu/drm/panel/panel-samsung-s6e63m0.c new file mode 100644 index 000000000000..4312aa3e4386 --- /dev/null +++ b/drivers/gpu/drm/panel/panel-samsung-s6e63m0.c @@ -0,0 +1,517 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * S6E63M0 AMOLED LCD drm_panel driver. + * + * Copyright (C) 2019 Paweł Chmiel + * Derived from drivers/gpu/drm/panel-samsung-ld9040.c + * + * Andrzej Hajda + */ + +#include +#include +#include + +#include +#include +#include +#include +#include +#include + +#include
