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

+- 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-0:
+    Usage: required
+    Value type: <prop-encoded-array>
+    Definition: List of pinctrl settings to apply to keep HSIC pins in a glitch
