| 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/video/display-timing.txt for display |
| timing binding details. |
| |
| 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>; |
| 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>; |
| }; |
| }; |
| }; |
