ROCKCHIP HDMI PHY WITH INNO IP BLOCK
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : should be one of the listed compatibles:
|
||
|
|
* "rockchip,rk3228-hdmi-phy",
|
||
|
|
* "rockchip,rk3328-hdmi-phy";
|
||
|
|
- reg : Address and length of the hdmi phy control register set
|
||
|
|
- clocks : phandle + clock specifier for the phy clocks
|
||
|
|
- clock-names : string, clock name, must contain "sysclk" for system
|
||
|
|
control and register configuration, "refoclk" for crystal-
|
||
|
|
oscillator reference PLL clock input and "refpclk" for pclk-
|
||
|
|
based refeference PLL clock input.
|
||
|
|
- #clock-cells: should be 0.
|
||
|
|
- clock-output-names : shall be the name for the output clock.
|
||
|
|
- interrupts : phandle + interrupt specified for the hdmiphy interrupt
|
||
|
|
- #phy-cells : must be 0. See ./phy-bindings.txt for details.
|
||
|
|
|
||
|
|
Optional properties for rk3328-hdmi-phy:
|
||
|
|
- nvmem-cells = phandle + nvmem specifier for the cpu-version efuse
|
||
|
|
- nvmem-cell-names : "cpu-version" to read the chip version, required
|
||
|
|
for adjustment to some frequency settings
|
||
|
|
|
||
|
|
Example:
|
||
|
|
hdmi_phy: hdmi-phy@12030000 {
|
||
|
|
compatible = "rockchip,rk3228-hdmi-phy";
|
||
|
|
reg = <0x12030000 0x10000>;
|
||
|
|
#phy-cells = <0>;
|
||
|
|
clocks = <&cru PCLK_HDMI_PHY>, <&xin24m>, <&cru DCLK_HDMIPHY>;
|
||
|
|
clock-names = "sysclk", "refoclk", "refpclk";
|
||
|
|
#clock-cells = <0>;
|
||
|
|
clock-output-names = "hdmi_phy";
|
||
|
|
status = "disabled";
|
||
|
|
};
|
||
|
|
|
||
|
|
Then the PHY can be used in other nodes such as:
|
||
|
|
|
||
|
|
hdmi: hdmi@200a0000 {
|
||
|
|
compatible = "rockchip,rk3228-dw-hdmi";
|
||
|
|
...
|
||
|
|
phys = <&hdmi_phy>;
|
||
|
|
phy-names = "hdmi";
|
||
|
|
...
|
||
|
|
};
