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>;
};
};
};
