1ROCKCHIP HDMI PHY WITH INNO IP BLOCK 2 3Required properties: 4 - compatible : should be one of the listed compatibles: 5 * "rockchip,rk3228-hdmi-phy", 6 * "rockchip,rk3328-hdmi-phy"; 7 - reg : Address and length of the hdmi phy control register set 8 - clocks : phandle + clock specifier for the phy clocks 9 - clock-names : string, clock name, must contain "sysclk" for system 10 control and register configuration, "refoclk" for crystal- 11 oscillator reference PLL clock input and "refpclk" for pclk- 12 based refeference PLL clock input. 13 - #clock-cells: should be 0. 14 - clock-output-names : shall be the name for the output clock. 15 - interrupts : phandle + interrupt specified for the hdmiphy interrupt 16 - #phy-cells : must be 0. See ./phy-bindings.txt for details. 17 18Optional properties for rk3328-hdmi-phy: 19 - nvmem-cells = phandle + nvmem specifier for the cpu-version efuse 20 - nvmem-cell-names : "cpu-version" to read the chip version, required 21 for adjustment to some frequency settings 22 23Example: 24 hdmi_phy: hdmi-phy@12030000 { 25 compatible = "rockchip,rk3228-hdmi-phy"; 26 reg = <0x12030000 0x10000>; 27 #phy-cells = <0>; 28 clocks = <&cru PCLK_HDMI_PHY>, <&xin24m>, <&cru DCLK_HDMIPHY>; 29 clock-names = "sysclk", "refoclk", "refpclk"; 30 #clock-cells = <0>; 31 clock-output-names = "hdmi_phy"; 32 status = "disabled"; 33 }; 34 35Then the PHY can be used in other nodes such as: 36 37 hdmi: hdmi@200a0000 { 38 compatible = "rockchip,rk3228-dw-hdmi"; 39 ... 40 phys = <&hdmi_phy>; 41 phy-names = "hdmi"; 42 ... 43 };
