1Device-Tree bindings for tilcdc DRM generic panel output driver 2This binding is deprecated and should not be used. 3 4Required properties: 5 - compatible: value should be "ti,tilcdc,panel". 6 - panel-info: configuration info to configure LCDC correctly for the panel 7 - ac-bias: AC Bias Pin Frequency 8 - ac-bias-intrpt: AC Bias Pin Transitions per Interrupt 9 - dma-burst-sz: DMA burst size 10 - bpp: Bits per pixel 11 - fdd: FIFO DMA Request Delay 12 - sync-edge: Horizontal and Vertical Sync Edge: 0=rising 1=falling 13 - sync-ctrl: Horizontal and Vertical Sync: Control: 0=ignore 14 - raster-order: Raster Data Order Select: 1=Most-to-least 0=Least-to-most 15 - fifo-th: DMA FIFO threshold 16 - display-timings: typical videomode of lcd panel. Multiple video modes 17 can be listed if the panel supports multiple timings, but the 'native-mode' 18 should be the preferred/default resolution. Refer to 19 Documentation/devicetree/bindings/display/panel/display-timing.txt for display 20 timing binding details. 21 22Optional properties: 23- backlight: phandle of the backlight device attached to the panel 24- enable-gpios: GPIO pin to enable or disable the panel 25 26Recommended properties: 27 - pinctrl-names, pinctrl-0: the pincontrol settings to configure 28 muxing properly for pins that connect to TFP410 device 29 30Example: 31 32 /* Settings for CDTech_S035Q01 / LCD3 cape: */ 33 lcd3 { 34 compatible = "ti,tilcdc,panel"; 35 pinctrl-names = "default"; 36 pinctrl-0 = <&bone_lcd3_cape_lcd_pins>; 37 backlight = <&backlight>; 38 enable-gpios = <&gpio3 19 0>; 39 40 panel-info { 41 ac-bias = <255>; 42 ac-bias-intrpt = <0>; 43 dma-burst-sz = <16>; 44 bpp = <16>; 45 fdd = <0x80>; 46 sync-edge = <0>; 47 sync-ctrl = <1>; 48 raster-order = <0>; 49 fifo-th = <0>; 50 }; 51 display-timings { 52 native-mode = <&timing0>; 53 timing0: 320x240 { 54 hactive = <320>; 55 vactive = <240>; 56 hback-porch = <21>; 57 hfront-porch = <58>; 58 hsync-len = <47>; 59 vback-porch = <11>; 60 vfront-porch = <23>; 61 vsync-len = <2>; 62 clock-frequency = <8000000>; 63 hsync-active = <0>; 64 vsync-active = <0>; 65 }; 66 }; 67 }; 68
