+* Universal Flash Storage (UFS) Host Controller
+
+UFSHC nodes are defined to describe on-chip UFS host controllers.
+Each UFS controller instance should have its own node.
+
+Required properties:
+- compatible : compatible list, contains "jedec,ufs-1.1"
+- interrupts : <interrupt mapping for UFS host controller IRQ>
+- reg : <registers mapping>
+
+Example:
+ ufshc@0xfc598000 {
+ compatible = "jedec,ufs-1.1";
+ reg = <0xfc598000 0x800>;
+ interrupts = <0 28 0>;
+ };
