rk3399 — pcie phy dts配置
1、必需设置属性值：
- compatible: 设置为：rockchip,rk3399-pcie-phy - #phy-cells: 必需为0 - clocks: 设置refclk时钟 - clock-names:取名为 "refclk" - resets: 设置phy的复位。 - reset-names: 取名为 "phy"
2、以rk3399为例：
grf: syscon@ff770000 {
compatible = "rockchip,rk3399-grf", "syscon", "simple-mfd";
#address-cells = <1>;
#size-cells = <1>;
...
pcie_phy: pcie-phy {
compatible = "rockchip,rk3399-pcie-phy";
#phy-cells = <0>;
clocks = <&cru SCLK_PCIEPHY_REF>;
clock-names = "refclk";
resets = <&cru SRST_PCIEPHY>;
reset-names = "phy";
};
};
