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,r8a7795-hdmi" for R8A7795 (R-Car H3) compatible HDMI TX 18 - "renesas,r8a7796-hdmi" for R8A7796 (R-Car M3-W) compatible HDMI TX 19 - "renesas,r8a77965-hdmi" for R8A77965 (R-Car M3-N) compatible HDMI TX 20 - "renesas,rcar-gen3-hdmi" for the generic R-Car Gen3 and RZ/G2 compatible 21 HDMI TX 22 23 When compatible with generic versions, nodes must list the SoC-specific 24 version corresponding to the platform first, followed by the 25 family-specific version. 26 27- reg: See dw_hdmi.txt. 28- interrupts: HDMI interrupt number 29- clocks: See dw_hdmi.txt. 30- clock-names: Shall contain "iahb" and "isfr" as defined in dw_hdmi.txt. 31- ports: See dw_hdmi.txt. The DWC HDMI shall have one port numbered 0 32 corresponding to the video input of the controller and one port numbered 1 33 corresponding to its HDMI output, and one port numbered 2 corresponding to 34 sound input of the controller. Each port shall have a single endpoint. 35 36Optional properties: 37 38- power-domains: Shall reference the power domain that contains the DWC HDMI, 39 if any. 40 41 42Example: 43 44 hdmi0: hdmi@fead0000 { 45 compatible = "renesas,r8a7795-dw-hdmi"; 46 reg = <0 0xfead0000 0 0x10000>; 47 interrupts = <0 389 IRQ_TYPE_LEVEL_HIGH>; 48 clocks = <&cpg CPG_CORE R8A7795_CLK_S0D4>, <&cpg CPG_MOD 729>; 49 clock-names = "iahb", "isfr"; 50 power-domains = <&sysc R8A7795_PD_ALWAYS_ON>; 51 52 ports { 53 #address-cells = <1>; 54 #size-cells = <0>; 55 port@0 { 56 reg = <0>; 57 dw_hdmi0_in: endpoint { 58 remote-endpoint = <&du_out_hdmi0>; 59 }; 60 }; 61 port@1 { 62 reg = <1>; 63 rcar_dw_hdmi0_out: endpoint { 64 remote-endpoint = <&hdmi0_con>; 65 }; 66 }; 67 port@2 { 68 reg = <2>; 69 rcar_dw_hdmi0_sound_in: endpoint { 70 remote-endpoint = <&hdmi_sound_out>; 71 }; 72 }; 73 }; 74 }; 75 76 hdmi0-out { 77 compatible = "hdmi-connector"; 78 label = "HDMI0 OUT"; 79 type = "a"; 80 81 port { 82 hdmi0_con: endpoint { 83 remote-endpoint = <&rcar_dw_hdmi0_out>; 84 }; 85 }; 86 }; 87
