Note for rob+dt:
Used enum to "soon" be able to add "rockchip,rk3128-inno-hdmi"

Changed V1:
Rename file to more common layout
Add/fix hdmi_out port example

-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>;
-
- 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>;
- };
