Renesas Gen3 DWC HDMI TX Encoder
================================
The HDMI transmitter is a Synopsys DesignWare HDMI 1.4 TX controller IP
with a companion 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 one or more of
- "renesas,r8a7795-hdmi" for R8A7795 (R-Car H3) compatible HDMI TX
- "renesas,r8a7796-hdmi" for R8A7796 (R-Car M3-W) compatible HDMI TX
- "renesas,r8a77965-hdmi" for R8A77965 (R-Car M3-N) compatible HDMI TX
- "renesas,rcar-gen3-hdmi" for the generic R-Car Gen3 compatible HDMI TX
When compatible with generic versions, nodes must list the SoC-specific
version corresponding to the platform first, followed by the
family-specific version.
- reg: See dw_hdmi.txt.
- interrupts: HDMI interrupt number
- clocks: See dw_hdmi.txt.
- clock-names: Shall 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, and one port numbered 2 corresponding to
sound input of the controller. Each port shall have a single endpoint.
Optional properties:
- power-domains: Shall reference the power domain that contains the DWC HDMI,
if any.
Example:
hdmi0: hdmi@fead0000 {
compatible = "renesas,r8a7795-dw-hdmi";
reg = <0 0xfead0000 0 0x10000>;
interrupts = <0 389 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&cpg CPG_CORE R8A7795_CLK_S0D4>, <&cpg CPG_MOD 729>;
clock-names = "iahb", "isfr";
power-domains = <&sysc R8A7795_PD_ALWAYS_ON>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
dw_hdmi0_in: endpoint {
remote-endpoint = <&du_out_hdmi0>;
};
};
port@1 {
reg = <1>;
rcar_dw_hdmi0_out: endpoint {
remote-endpoint = <&hdmi0_con>;
};
};
port@2 {
reg = <2>;
rcar_dw_hdmi0_sound_in: endpoint {
remote-endpoint = <&hdmi_sound_out>;
};
};
};
};
hdmi0-out {
compatible = "hdmi-connector";
label = "HDMI0 OUT";
type = "a";
port {
hdmi0_con: endpoint {
remote-endpoint = <&rcar_dw_hdmi0_out>;
};
};
};
