-* Cadence Universal Flash Storage (UFS) Controller

-UFS nodes are defined to describe on-chip UFS host controllers.
-Each UFS controller instance should have its own node.
-Please see the ufshcd-pltfrm.txt for a list of all available properties.
-
-Required properties:
-- compatible	: Compatible list, contains one of the following controllers:
-			"cdns,ufshc" - Generic CDNS HCI,
-			"cdns,ufshc-m31-16nm" - CDNS UFS HC + M31 16nm PHY
-		  complemented with the JEDEC version:
-			"jedec,ufs-2.0"
-
-- reg		: Address and length of the UFS register set.
-- interrupts	: One interrupt mapping.
-- freq-table-hz	: Clock frequency table.
-		  See the ufshcd-pltfrm.txt for details.
-- clocks	: List of phandle and clock specifier pairs.
-- clock-names	: List of clock input name strings sorted in the same
-		  order as the clocks property. "core_clk" is mandatory.
-		  Depending on a type of a PHY,
-		  the "phy_clk" clock can also be added, if needed.
-
-Example:
-	ufs@fd030000 {
-		compatible = "cdns,ufshc", "jedec,ufs-2.0";
-		reg = <0xfd030000 0x10000>;

-		clock-names = "core_clk", "phy_clk";
