-- compatible:
-    Usage: required
-    Value type: <string>
-    Definition: Should contain "qcom,usb-hsic-phy" and more specifically one of the
-		following:
-
-			"qcom,usb-hsic-phy-mdm9615"
-			"qcom,usb-hsic-phy-msm8974"

-- #phy-cells:
-    Usage: required
-    Value type: <u32>
-    Definition: Should contain 0
-
-- clocks:
-    Usage: required
-    Value type: <prop-encoded-array>
-    Definition: Should contain clock specifier for phy, calibration and
-                a calibration sleep clock
-
-- clock-names:
-    Usage: required
-    Value type: <stringlist>
-    Definition: Should contain "phy, "cal" and "cal_sleep"

-- pinctrl-names:
-    Usage: required
-    Value type: <stringlist>
-    Definition: Should contain "init" and "default" in that order
-
-- pinctrl-0:
-    Usage: required
-    Value type: <prop-encoded-array>
-    Definition: List of pinctrl settings to apply to keep HSIC pins in a glitch
