hi simon,
I need to achieve emmc_phy physical address in driver, so that I can configure phy in different scenarios (phy register address should be 0xff77f780). see below: sdhci: sdhci@fe330000 {
phys = <&emmc_phy>; phy-names = "phy_arasan";
};
grf: syscon@ff770000 { reg = <0x0 0xff770000 0x0 0x10000>;
emmc_phy: phy@f780 { compatible = "rockchip,rk3399-emmc-phy"; reg = <0xf780 0x24>; #phy-cells = <0>; status = "disabled"; }; };
AKA, I can't use libfdt if OF_PLATDATA is enabled, so how to get it?
