Rockchip specific extensions to the Innosilicon HDMI
================================
Required properties:
- compatible:
"rockchip,rk3036-inno-hdmi";
- reg:
Physical base address and length of the controller's registers.
- clocks, clock-names:
Phandle to hdmi controller clock, name should be "pclk"
- interrupts:
HDMI interrupt number
- ports:
Contain one port node with endpoint definitions as defined in
Documentation/devicetree/bindings/graph.txt.
- pinctrl-0, pinctrl-name:
Switch the iomux of HPD/CEC pins to HDMI function.
Example:
hdmi: hdmi@20034000 {
compatible = "rockchip,rk3036-inno-hdmi";
reg = <0x20034000 0x4000>;
interrupts = <GIC_SPI 45 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&cru PCLK_HDMI>;
clock-names = "pclk";
pinctrl-names = "default";
pinctrl-0 = <&hdmi_ctl>;
status = "disabled";
hdmi_in: port {
#address-cells = <1>;
#size-cells = <0>;
hdmi_in_lcdc: endpoint@0 {
reg = <0>;
remote-endpoint = <&lcdc_out_hdmi>;
};
};
};
&pinctrl {
hdmi {
hdmi_ctl: hdmi-ctl {
rockchip,pins = <1 8 RK_FUNC_1 &pcfg_pull_none>,
<1 9 RK_FUNC_1 &pcfg_pull_none>,
<1 10 RK_FUNC_1 &pcfg_pull_none>,
<1 11 RK_FUNC_1 &pcfg_pull_none>;
};
};
};
