* MSM Universal Flash Storage (UFS) PHY

UFSPHY nodes are defined to describe on-chip UFS PHY hardware macro.
Each UFS PHY node should have its own node.

To bind UFS PHY with UFS host controller, the controller node should
contain a phandle reference to UFS PHY node.

Required properties:
- compatible        : compatible list, contains "qcom,ufsphy"
- reg               : <registers mapping>
- vdda-phy-supply   : phandle to main PHY supply for analog domain
- vdda-pll-supply   : phandle to PHY PLL and Power-Gen block power supply

Optional properties:
- vdda-phy-max-microamp : specifies max. load that can be drawn from phy supply
- vdda-pll-max-microamp : specifies max. load that can be drawn from pll supply

Example:

	ufsphy1: ufsphy@0xfc597000 {
		compatible = "qcom,ufsphy";
		reg = <0xfc597000 0x800>;
		vdda-phy-supply = <&pma8084_l4>;
		vdda-pll-supply = <&pma8084_l12>;
		vdda-phy-max-microamp = <50000>;
		vdda-pll-max-microamp = <1000>;
	};

	ufshc@0xfc598000 {
		...
		ufs-phy = <&ufsphy1>;
	};
