Signed-off-by: Dario Binacchi Reviewed-by: Raphaël Gallais-Pou --- Changes in v5: I am confident that framebuffer sizing is a real requirement for STM32 boards, but I need some time to understand if and how to introduce this functionality. Therefore, I drop the following patches to allow the series to be fully merged: - [4/6] dt-bindings: display: stm32-ltdc: add optional st,fb-bpp property - [5/6] ARM: dts: stm32: set framebuffer bit depth on stm32f746-disco - [6/6] drm/stm: set framebuffer bit depth through DTS property Changes in v4: - Use DTS property instead of module parameter to set the framebuffer bit depth. Changes in v3: - drop [4/6] dt-bindings: display: simple: add Rocktech RK043FN48H Applied to https://anongit.freedesktop.org/git/drm/drm-misc.git (drm-misc-next): https://cgit.freedesktop.org/drm/drm-misc/commit/?id=c42a37a27c777d63961dd634a30f7c887949491a - drop [5/6] drm/panel: simple: add support for Rocktech RK043FN48H panel Applied to https://anongit.freedesktop.org/git/drm/drm-misc.git (drm-misc-next) https://cgit.freedesktop.org/drm/drm-misc/commit/?id=13cdd12a9f934158f4ec817cf048fcb4384aa9dc arch/arm/boot/dts/stm32f746-disco.dts | 51 +++++++++++++++++++++++++++ 1 file changed, 51 insertions(+) diff --git a/arch/arm/boot/dts/stm32f746-disco.dts b/arch/arm/boot/dts/stm32f746-disco.dts index c11616ed5fc6..cda423b6a874 100644 --- a/arch/arm/boot/dts/stm32f746-disco.dts +++ b/arch/arm/boot/dts/stm32f746-disco.dts @@ -60,10 +60,41 @@ memory@c0000000 { reg = <0xC0000000 0x800000>; }; + reserved-memory { + #address-cells = <1>; + #size-cells = <1>; + ranges; + + linux,cma { + compatible = "shared-dma-pool"; + no-map; + size = <0x80000>; + linux,dma-default; + }; + }; + aliases { serial0 = &usart1; }; + backlight: backlight { + compatible = "gpio-backlight"; + gpios = <&gpiok 3 GPIO_ACTIVE_HIGH>; + status = "okay"; + }; + + panel_rgb: panel-rgb { + compatible = "rocktech,rk043fn48h"; + backlight = <&backlight>; + enable-gpios = <&gpioi 12 GPIO_ACTIVE_HIGH>; + status = "okay"; + port { + panel_in_rgb: endpoint { + remote-endpoint = <<dc_out_rgb>; + }; + }; + }; + usbotg_hs_phy: usb-phy { #phy-cells = <0>; compatible = "usb-nop-xceiv"; @@ -99,6 +130,26 @@ &i2c1 { status = "okay"; }; +&dma1 { + status = "okay"; +}; + +&dma2 { + status = "okay"; +}; + +<dc { + pinctrl-0 = <<dc_pins_a>; + pinctrl-names = "default"; + status = "okay"; + + port { + ltdc_out_rgb: endpoint { + remote-endpoint = <&panel_in_rgb>; + }; + }; +}; + &sdio1 { status = "okay"; vmmc-supply = <&mmc_vcard>;
