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 |
|
|
|

|
|
|
/* Settings for CDTech_S035Q01 / LCD3 cape: */ |
|
