0001 Device-Tree bindings for tilcdc DRM generic panel output driver
0002
0003 Required properties:
0004 - compatible: value should be "ti,tilcdc,panel".
0005 - panel-info: configuration info to configure LCDC correctly for the panel
0006 - ac-bias: AC Bias Pin Frequency
0007 - ac-bias-intrpt: AC Bias Pin Transitions per Interrupt
0008 - dma-burst-sz: DMA burst size
0009 - bpp: Bits per pixel
0010 - fdd: FIFO DMA Request Delay
0011 - sync-edge: Horizontal and Vertical Sync Edge: 0=rising 1=falling
0012 - sync-ctrl: Horizontal and Vertical Sync: Control: 0=ignore
0013 - raster-order: Raster Data Order Select: 1=Most-to-least 0=Least-to-most
0014 - fifo-th: DMA FIFO threshold
0015 - display-timings: typical videomode of lcd panel. Multiple video modes
0016 can be listed if the panel supports multiple timings, but the 'native-mode'
0017 should be the preferred/default resolution. Refer to
0018 Documentation/devicetree/bindings/display/panel/display-timing.txt for display
0019 timing binding details.
0020
0021 Optional properties:
0022 - backlight: phandle of the backlight device attached to the panel
0023 - enable-gpios: GPIO pin to enable or disable the panel
0024
0025 Recommended properties:
0026 - pinctrl-names, pinctrl-0: the pincontrol settings to configure
0027 muxing properly for pins that connect to TFP410 device
0028
