+* Hisilicon Universal Flash Storage (UFS) Host Controller
+
+UFS nodes are defined to describe on-chip UFS hardware macro.
+Each UFS Host Controller should have its own node.
+
+Required properties:
+- compatible : compatible list, contains one of the following -
+ "hisilicon,hi3660-ufs", "jedec,ufs-1.1" for hisi ufs
+ host controller present on Hi36xx chipset.
+- reg : should contain UFS register address space & UFS SYS CTRL register address,
+- interrupt-parent : interrupt device
+- interrupts : interrupt number
+- 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. "ref_clk", "phy_clk" is optional
+- resets : reset node register, one reset the clk and the other reset the controller
+- reset-names : describe reset node register
+
+Example:
+
+ ufs: ufs@ff3b0000 {
+ compatible = "hisilicon,hi3660-ufs", "jedec,ufs-1.1";
+ /* 0: HCI standard */
+ /* 1: UFS SYS CTRL */
+ reg = <0x0 0xff3b0000 0x0 0x1000>,
+ <0x0 0xff3b1000 0x0 0x1000>;
+ interrupt-parent = <&gic>;
+ interrupts = <GIC_SPI 278 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&crg_ctrl HI3660_CLK_GATE_UFSIO_REF>,
+ <&crg_ctrl HI3660_CLK_GATE_UFSPHY_CFG>;
+ clock-names = "ref_clk", "phy_clk";
+ /* offset: 0x84; bit: 12 */
+ /* offset: 0x84; bit: 7 */
+ resets = <&crg_rst 0x84 12>,
+ <&crg_rst 0x84 7>;
+ reset-names = "rst", "assert";
+ };
