New bindings in DT Schema format please (.yaml files). We are working on migrating all bindings to DT Schema format.

+The HDMI transmitter is a Synopsys DesignWare HDMI 2.0 TX controller IP +with a companion of Synopsys DesignWare HDMI 2.0 TX PHY IP.
+These DT bindings follow the Synopsys DWC HDMI TX bindings defined in +Documentation/devicetree/bindings/display/bridge/dw_hdmi.txt +with the following device-specific properties.
+Required properties:
+- compatible : Shall contain
- "snps,dw-hdmi-hsdk" for HSDK4xD compatible HDMI TX
+- reg: See dw_hdmi.txt. +- interrupts: HDMI interrupt number. +- clocks: See dw_hdmi.txt. +- clock-names: Must contain "iahb" and "isfr" as defined in dw_hdmi.txt. +- ports: See dw_hdmi.txt. The DWC HDMI shall have one port numbered 0
- corresponding to the video input of the controller and one port numbered 1
- corresponding to its HDMI output.
+Example:
+hdmi: hdmi@0x10000 {
- compatible = "snps,dw-hdmi-hsdk";
- reg = <0x10000 0x10000>;
- reg-io-width = <4>;
- interrupts = <14>;
- clocks = <&apbclk>, <&hdmi_pix_clk>;
- clock-names = "iahb", "isfr";
- ports {
#address-cells = <1>;#size-cells = <0>;port@0 {reg = <0>;hdmi_enc_input: endpoint {remote-endpoint = <&pgu_output>;};};port@1 {reg = <1>;hdmi_enc_out: endpoint {remote-endpoint = <&hdmi_con>;};};- };
+};
+hdmi-out {
- ...
- port {
hdmi_con: endpoint {remote-endpoint = <&hdmi_enc_out>;};- };
+};
+pgu {
- ...
- port_o: port {
pgu_output: endpoint {remote-endpoint = <&hdmi_enc_input>;};- };
+};
