1Renesas Gen3 DWC HDMI TX Encoder 2================================ 3 4The HDMI transmitter is a Synopsys DesignWare HDMI 1.4 TX controller IP 5with a companion PHY IP. 6 7These DT bindings follow the Synopsys DWC HDMI TX bindings defined in 8Documentation/devicetree/bindings/display/bridge/dw_hdmi.txt with the 9following device-specific properties. 10 11 12Required properties: 13 14- compatible : Shall contain one or more of 15 - "renesas,r8a774a1-hdmi" for R8A774A1 (RZ/G2M) compatible HDMI TX 16 - "renesas,r8a774b1-hdmi" for R8A774B1 (RZ/G2N) compatible HDMI TX 17 - "renesas,r8a774e1-hdmi" for R8A774E1 (RZ/G2H) compatible HDMI TX 18 - "renesas,r8a7795-hdmi" for R8A7795 (R-Car H3) compatible HDMI TX 19 - "renesas,r8a7796-hdmi" for R8A7796 (R-Car M3-W) compatible HDMI TX 20 - "renesas,r8a77961-hdmi" for R8A77961 (R-Car M3-W+) compatible HDMI TX 21 - "renesas,r8a77965-hdmi" for R8A77965 (R-Car M3-N) compatible HDMI TX 22 - "renesas,rcar-gen3-hdmi" for the generic R-Car Gen3 and RZ/G2 compatible 23 HDMI TX 24 25 When compatible with generic versions, nodes must list the SoC-specific 26 version corresponding to the platform first, followed by the 27 family-specific version. 28 29- reg: See dw_hdmi.txt. 30- interrupts: HDMI interrupt number 31- clocks: See dw_hdmi.txt. 32- clock-names: Shall contain "iahb" and "isfr" as defined in dw_hdmi.txt. 33- ports: See dw_hdmi.txt. The DWC HDMI shall have one port numbered 0 34 corresponding to the video input of the controller and one port numbered 1 35 corresponding to its HDMI output, and one port numbered 2 corresponding to 36 sound input of the controller. Each port shall have a single endpoint. 37 38Optional properties: 39 40- power-domains: Shall reference the power domain that contains the DWC HDMI, 41 if any. 42 43 44Example: 45 46 hdmi0: hdmi@fead0000 { 47 compatible = "renesas,r8a7795-hdmi", "renesas,rcar-gen3-hdmi"; 48 reg = <0 0xfead0000 0 0x10000>; 49 interrupts = <0 389 IRQ_TYPE_LEVEL_HIGH>; 50 clocks = <&cpg CPG_CORE R8A7795_CLK_S0D4>, <&cpg CPG_MOD 729>; 51 clock-names = "iahb", "isfr"; 52 power-domains = <&sysc R8A7795_PD_ALWAYS_ON>; 53 54 ports { 55 #address-cells = <1>; 56 #size-cells = <0>; 57 port@0 { 58 reg = <0>; 59 dw_hdmi0_in: endpoint { 60 remote-endpoint = <&du_out_hdmi0>; 61 }; 62 }; 63 port@1 { 64 reg = <1>; 65 rcar_dw_hdmi0_out: endpoint { 66 remote-endpoint = <&hdmi0_con>; 67 }; 68 }; 69 port@2 { 70 reg = <2>; 71 rcar_dw_hdmi0_sound_in: endpoint { 72 remote-endpoint = <&hdmi_sound_out>; 73 }; 74 }; 75 }; 76 }; 77 78 hdmi0-out { 79 compatible = "hdmi-connector"; 80 label = "HDMI0 OUT"; 81 type = "a"; 82 83 port { 84 hdmi0_con: endpoint { 85 remote-endpoint = <&rcar_dw_hdmi0_out>; 86 }; 87 }; 88 }; 89
