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