+* Mediatek 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.
+
+To bind UFS PHY with UFS host controller, the controller node should
+contain a phandle reference to UFS M-PHY node.
+
+Required properties for UFS nodes:
+- compatible : Compatible list, contains the following controller:
+ "mediatek,mt8183-ufshci" for MediaTek UFS host controller
+ present on MT81xx chipsets.
+- reg : Address and length of the UFS register set.
+- phys : phandle to m-phy.
+- 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. "ufs" is mandatory.
+ "ufs": ufshci core control clock.
+- freq-table-hz : Array of <min max> operating frequencies stored in the same
+ order as the clocks property. If this property is not
+ defined or a value in the array is "0" then it is assumed
+ that the frequency is set by the parent clock or a
+ fixed rate clock source.
+- vcc-supply : phandle to VCC supply regulator node.
+
+Example:
+
+ ufsphy: phy@11fa0000 {
+ ...
+ };
+
+ ufshci@11270000 {
+ compatible = "mediatek,mt8183-ufshci";
+ reg = <0 0x11270000 0 0x2300>;
+ interrupts = <GIC_SPI 104 IRQ_TYPE_LEVEL_LOW>;
+ phys = <&ufsphy>;
+
+ clocks = <&infracfg_ao INFRACFG_AO_UFS_CG>;
+ clock-names = "ufs";
+ freq-table-hz = <0 0>;
+
+ vcc-supply = <&mt_pmic_vemc_ldo_reg>;
+ };
