-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.
-
-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>;
