+Required properties:
+ - compatible: "qcom,ipq4019-usb-ss-phy",
+ "qcom,ipq4019-usb-hs-phy"
+ - reg: offset and length of the registers
+ - #phy-cells: should be 0
+ - resets: the reset controllers as listed below
+ - reset-names: the names of the reset controllers
+ "por" - the POR reset line for SS and HS phys
+ "srif" - the SRIF reset line for HS phys
+Example:
+
+usb-phy@a8000 {
+ compatible = "qcom,ipq4019-usb-hs-phy";
+ phy-cells = <0>;
+ reg = <0xa8000 0x40>;
+ resets = <&gcc USB2_HSPHY_POR_ARES>,
+ <&gcc USB2_HSPHY_S_ARES>;
