Device-Tree bindings for tilcdc DRM generic panel output driver Required properties: - compatible: value should be "ti,tilcdc,panel". - panel-info: configuration info to configure LCDC correctly for the panel - ac-bias: AC Bias Pin Frequency - ac-bias-intrpt: AC Bias Pin Transitions per Interrupt - dma-burst-sz: DMA burst size - bpp: Bits per pixel - fdd: FIFO DMA Request Delay - sync-edge: Horizontal and Vertical Sync Edge: 0=rising 1=falling - sync-ctrl: Horizontal and Vertical Sync: Control: 0=ignore - raster-order: Raster Data Order Select: 1=Most-to-least 0=Least-to-most - fifo-th: DMA FIFO threshold - display-timings: typical videomode of lcd panel. Multiple video modes can be listed if the panel supports multiple timings, but the 'native-mode' should be the preferred/default resolution. Refer to Documentation/devicetree/bindings/display/panel/display-timing.txt for display timing binding details. Optional properties: - backlight: phandle of the backlight device attached to the panel - enable-gpios: GPIO pin to enable or disable the panel Recommended properties: - pinctrl-names, pinctrl-0: the pincontrol settings to configure muxing properly for pins that connect to TFP410 device Example: /* Settings for CDTech_S035Q01 / LCD3 cape: */ lcd3 { compatible = "ti,tilcdc,panel"; pinctrl-names = "default"; pinctrl-0 = <&bone_lcd3_cape_lcd_pins>; backlight = <&backlight>; enable-gpios = <&gpio3 19 0>; panel-info { ac-bias = <255>; ac-bias-intrpt = <0>; dma-burst-sz = <16>; bpp = <16>; fdd = <0x80>; sync-edge = <0>; sync-ctrl = <1>; raster-order = <0>; fifo-th = <0>; }; display-timings { native-mode = <&timing0>; timing0: 320x240 { hactive = <320>; vactive = <240>; hback-porch = <21>; hfront-porch = <58>; hsync-len = <47>; vback-porch = <11>; vfront-porch = <23>; vsync-len = <2>; clock-frequency = <8000000>; hsync-active = <0>; vsync-active = <0>; }; }; };
