PXA LCD Controller
|
|
------------------
|
|
|
|
Required properties:
|
|
- compatible : one of these
|
|
"marvell,pxa2xx-lcdc",
|
|
"marvell,pxa270-lcdc",
|
|
"marvell,pxa300-lcdc"
|
|
- reg : should contain 1 register range (address and length).
|
|
- interrupts : framebuffer controller interrupt.
|
|
- clocks: phandle to input clocks
|
|
|
|
Required nodes:
|
|
- port: connection to the LCD panel (see video-interfaces.txt)
|
|
This node must have its properties bus-width and remote-endpoint set.
|
|
If the panel is not a TFT color panel, then a "lcd-type" property in
|
|
the panel should specify the panel type.
|
|
This panel node should be in the board dts.
|
|
|
|
Example:
|
|
lcd-controller@40500000 {
|
|
compatible = "marvell,pxa2xx-lcdc";
|
|
reg = <0x44000000 0x10000>;
|
|
interrupts = <17>;
|
|
clocks = <&clks CLK_LCD>;
|
|
status = "okay";
|
|
|
|
port {
|
|
lcdc_out: endpoint {
|
|
remote-endpoint = <&panel_in>;
|
|
bus-width = <16>;
|
|
};
|
|
};
|
|
};
