+LCD Controller is the Display Controller for the Ingenic JZ4780 SoC
+Required properties: +- compatible: should be "ingenic,jz4780-lcd" +- reg: Should contain the address & size of the LCD controller registers. +- interrupts: Should specify the interrupt provided by parent. +- clocks: Should contain two clock specifiers for the JZ4780_CLK_TVE JZ4780_CLK_LCD0PIXCLK. +- clock-names : Must be "lcd_clk", "lcd_pixclk"; +- port: A port node with endpoint definitions as defined in
- Documentation/devicetree/bindings/media/video-interfaces.txt.
+Optional properties: +- interrupt-parent: phandle to parent interrupt controller
Drop this. 'interrupt-parent' is always valid and could be in a parent node.
+Example:
+lcd: jz4780-lcdk@0x13050000 {
Drop the '0x'.
- compatible = "ingenic,jz4780-lcd";
- reg = <0x13050000 0x1800>;
- clocks = <&cgu JZ4780_CLK_TVE>, <&cgu JZ4780_CLK_LCD0PIXCLK>;
- clock-names = "lcd_clk", "lcd_pixclk";
- interrupt-parent = <&intc>;
- interrupts = <31>;
- jz4780_lcd_out: port {
#address-cells = <1>;
#size-cells = <0>;
jz4780_out_hdmi: endpoint@0 {
reg = <0>;
Don't need an address as there's only 1 endpoint.
remote-endpoint = <&hdmi_in_lcd>;
};
};
