RK3588S平台的M.2 接口SATA驱动配置

本文以RK3588S平台的M.2 接口SATA实际开发硬件为例分享经验

1.硬件连接

SATA 连接到PCIE Mux0上 1lane连接

2.DTS设备树配置

Mux0的PHY(combphy0_ps)工作于SATA模式

&combphy0_ps {
	status = "okay";
};

使能SATA0

&sata0 {
	status = "okay";
	vin-supply = <&VCC3v3_M2SSD>;
};

 配置电源

	VCC3v3_M2SSD: VCC3v3-M2SSD { 
		compatible = "regulator-fixed";
		regulator-name = "VCC3v3_M2SSD";
		regulator-alwa
