It also adds an instance in the device-tree and handle the inclusion of the driver within the DRM framework. First patch adds a new panel compatible in the panel-lvds driver, which is used by default on the STM32MP257. Changes in v2: - Dropped [1/8] because already merged - Dropped [4/8] since not mandatory for this serie - [1/6]: Switch compatible and clock-cells related areas - [1/6]: Remove faulty #include in the example. - [1/6]: Add missing entry in MAINTAINERS - [2/6]: Removed CamelCase macros - [2/6]: Removed hard to read debug log - [3/6]: Fixed my address - [3/6]: Fixed smatch warning - [5/6]: Move changes to stm32mp255.dtsi Raphael Gallais-Pou (6): dt-bindings: display: add dt-bindings for STM32 LVDS device drm/stm: lvds: add new STM32 LVDS Display Interface Transmitter driver drm/stm: ltdc: add lvds pixel clock arm64: dts: st: add ltdc support on stm32mp251 arm64: dts: st: add lvds support on stm32mp255 arm64: dts: st: add display support on stm32mp257f-ev .../bindings/display/st,stm32-lvds.yaml | 117 ++ MAINTAINERS | 1 + arch/arm64/boot/dts/st/stm32mp251.dtsi | 12 + arch/arm64/boot/dts/st/stm32mp255.dtsi | 17 + arch/arm64/boot/dts/st/stm32mp257f-ev1.dts | 79 ++ drivers/gpu/drm/stm/Kconfig | 11 + drivers/gpu/drm/stm/Makefile | 2 + drivers/gpu/drm/stm/ltdc.c | 19 + drivers/gpu/drm/stm/ltdc.h | 1 + drivers/gpu/drm/stm/lvds.c | 1225 +++++++++++++++++ 10 files changed, 1484 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/st,stm32-lvds.yaml create mode 100644 drivers/gpu/drm/stm/lvds.c
