Mediatek HDMI Encoder ===================== The Mediatek HDMI encoder can generate HDMI 1.4a or MHL 2.0 signals from its parallel input. Required properties: - compatible: Should be "mediatek,<chip>-hdmi". - reg: Physical base address and length of the controller's registers - interrupts: The interrupt signal from the function block. - clocks: device clocks See Documentation/devicetree/bindings/clock/clock-bindings.txt for details. - clock-names: must contain "pixel", "pll", "bclk", and "spdif". - phys: phandle link to the HDMI PHY node. See Documentation/devicetree/bindings/phy/phy-bindings.txt for details. - phy-names: must contain "hdmi" - mediatek,syscon-hdmi: phandle link and register offset to the system configuration registers. For mt8173 this must be offset 0x900 into the MMSYS_CONFIG region: <&mmsys 0x900>. - ports: A node containing input and output port nodes with endpoint definitions as documented in Documentation/devicetree/bindings/graph.txt. - port@0: The input port in the ports node should be connected to a DPI output port. - port@1: The output port in the ports node should be connected to the input port of a connector node that contains a ddc-i2c-bus property, or to the input port of an attached bridge chip, such as a SlimPort transmitter. HDMI CEC ======== The HDMI CEC controller handles hotplug detection and CEC communication. Required properties: - compatible: Should be "mediatek,<chip>-cec" - reg: Physical base address and length of the controller's registers - interrupts: The interrupt signal from the function block. - clocks: device clock HDMI DDC ======== The HDMI DDC i2c controller is used to interface with the HDMI DDC pins. The Mediatek's I2C controller is used to interface with I2C devices. Required properties: - compatible: Should be "mediatek,<chip>-hdmi-ddc" - reg: Physical base address and length of the controller's registers - clocks: device clock - clock-names: Should be "ddc-i2c". HDMI PHY ======== The HDMI PHY serializes the HDMI encoder's three channel 10-bit parallel output and drives the HDMI pads. Required properties: - compatible: "mediatek,<chip>-hdmi-phy" - reg: Physical base address and length of the module's registers - clocks: PLL reference clock - clock-names: must contain "pll_ref" - clock-output-names: must be "hdmitx_dig_cts" on mt8173 - #phy-cells: must be <0> - #clock-cells: must be <0> Optional properties: - mediatek,ibias: TX DRV bias current for <1.65Gbps, defaults to 0xa - mediatek,ibias_up: TX DRV bias current for >1.65Gbps, defaults to 0x1c Example: cec: cec@10013000 { compatible = "mediatek,mt8173-cec"; reg = <0 0x10013000 0 0xbc>; interrupts = <GIC_SPI 167 IRQ_TYPE_LEVEL_LOW>; clocks = <&infracfg CLK_INFRA_CEC>; }; hdmi_phy: hdmi-phy@10209100 { compatible = "mediatek,mt8173-hdmi-phy"; reg = <0 0x10209100 0 0x24>; clocks = <&apmixedsys CLK_APMIXED_HDMI_REF>; clock-names = "pll_ref"; clock-output-names = "hdmitx_dig_cts"; mediatek,ibias = <0xa>; mediatek,ibias_up = <0x1c>; #clock-cells = <0>; #phy-cells = <0>; }; hdmi_ddc0: i2c@11012000 { compatible = "mediatek,mt8173-hdmi-ddc"; reg = <0 0x11012000 0 0x1c>; interrupts = <GIC_SPI 81 IRQ_TYPE_LEVEL_LOW>; clocks = <&pericfg CLK_PERI_I2C5>; clock-names = "ddc-i2c"; }; hdmi0: hdmi@14025000 { compatible = "mediatek,mt8173-hdmi"; reg = <0 0x14025000 0 0x400>; interrupts = <GIC_SPI 206 IRQ_TYPE_LEVEL_LOW>; clocks = <&mmsys CLK_MM_HDMI_PIXEL>, <&mmsys CLK_MM_HDMI_PLLCK>, <&mmsys CLK_MM_HDMI_AUDIO>, <&mmsys CLK_MM_HDMI_SPDIF>; clock-names = "pixel", "pll", "bclk", "spdif"; pinctrl-names = "default"; pinctrl-0 = <&hdmi_pin>; phys = <&hdmi_phy>; phy-names = "hdmi"; mediatek,syscon-hdmi = <&mmsys 0x900>; assigned-clocks = <&topckgen CLK_TOP_HDMI_SEL>; assigned-clock-parents = <&hdmi_phy>; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; hdmi0_in: endpoint { remote-endpoint = <&dpi0_out>; }; }; port@1 { reg = <1>; hdmi0_out: endpoint { remote-endpoint = <&hdmi_con_in>; }; }; }; }; connector { compatible = "hdmi-connector"; type = "a"; ddc-i2c-bus = <&hdmiddc0>; port { hdmi_con_in: endpoint { remote-endpoint = <&hdmi0_out>; }; }; };
