Qualcomm Synopsys 28nm Femto phy controller
===========================================

Synopsys 28nm femto phy controller supports LS/FS/HS usb connectivity on
Qualcomm chipsets.

Required properties:
- compatible:
    Value type: <string>
    Definition: Should contain "qcom,usb-snps-hsphy".

- reg:
    Value type: <prop-encoded-array>
    Definition: USB PHY base address and length of the register map

- reg-names:
    Value type: <string>
    Definition: Names of the reg bases in 1-1 correspondence with the
		"reg" property. "phy_csr" is a mandatory reg base.

- clocks:
    Value type: <prop-encoded-array>
    Definition: See clock-bindings.txt section "consumers". List of
                two clock specifiers for interface and core controller
                clocks.

- clock-names:
    Value type: <string>
    Definition: Names of the clocks in 1-1 correspondence with the "clocks"
		property. Must contain "phy_csr_clk" and "ref_clk" clocks.

- vdd-supply:
    Value type: <phandle>
    Definition: phandle to the regulator VDD supply node.

- vdda18-supply:
    Value type: <phandle>
    Definition: phandle to the regulator 1.8V supply node.

- vdda33-supply:
    Value type: <phandle>
    Definition: phandle to the regulator 3.3V supply node.

- qcom,vdd-voltage-level:
    Value type: <prop-array>
    Definition: This is a list of three integer values (no, min, max) where
		each value corresponding to voltage corner.

- resets:
    Value type: <prop-encoded-array>
    Definition: See reset.txt section "consumers". PHY reset specifier.

- reset-names:
    Value type: <string>
    Definition: Must contain "phy_por_reset" and "phy_reset" strings.

Example:
	usb_phy: phy@78d9000 {
		compatible = "qcom,usb-snps-hsphy";
		reg = <0x78d9000 0x400>;
		reg-names = "phy_csr";

		vdd-supply = <&pm8916_s1_corner>;
		vdda18-supply = <&pm8916_l7>;
		vdda33-supply = <&pm8916_l13>;

		clocks = <&gcc GCC_USB_HS_AHB_CLK>,
			     <&gcc GCC_USB_HS_SYSTEM_CLK>;
		clock-names = "phy_csr_clk", "ref_clk";

		resets = <&gcc GCC_QUSB2_PHY_BCR>,
			 <&gcc GCC_USB2_HS_PHY_ONLY_BCR>;
		reset-names = "phy_por_reset", "phy_reset";
