-* Universal Flash Storage (UFS) DesignWare Host Controller
-
-DWC_UFS nodes are defined to describe on-chip UFS host controllers and MPHY.
-Each UFS controller instance should have its own node.
-
-Required properties:
-- compatible	: compatible list must contain the PHY type & version:
-			"snps,g210-tc-6.00-20bit"
-			"snps,g210-tc-6.00-40bit"
-		  complemented with the Controller IP version:
-			"snps,dwc-ufshcd-1.40a"
-		  complemented with the JEDEC version:
-			"jedec,ufs-1.1"
-			"jedec,ufs-2.0"
-
-- reg		: <registers mapping>
-- interrupts	: <interrupt mapping for UFS host controller IRQ>
-
-Example for a setup using a 1.40a DWC Controller with a 6.00 G210 40-bit TC:
-	dwc-ufs@d0000000 {
-		compatible = "snps,g210-tc-6.00-40bit",
-			     "snps,dwc-ufshcd-1.40a",
-			     "jedec,ufs-2.0";
-		reg = < 0xd0000000 0x10000 >;
-		interrupts = < 24 >;
-	};
