++Qualcom Dakota HS/SS USB PHY
++
++Required properties:
++ - compatible: "qcom,usb-ss-ipq4019-phy",
++	       "qcom,usb-hs-ipq4019-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_rst" - the POR reset line for SS and HS phys
++	"srif_rst" - the SRIF reset line for HS phys
++Example:
++
++hsphy@a8000 {
++	compatible = "qcom,usb-hs-ipq4019-phy";
++	phy-cells = <0>;
++	reg = <0xa8000 0x40>;
++	resets = <&gcc USB2_HSPHY_POR_ARES>,
++		 <&gcc USB2_HSPHY_S_ARES>;
++	reset-names = "por_rst", "srif_rst";
++};
