-MediaTek Universal Flash Storage (UFS) M-PHY binding
---------------------------------------------------------
-
-UFS M-PHY nodes are defined to describe on-chip UFS M-PHY hardware macro.
-Each UFS M-PHY node should have its own node.
-
-To bind UFS M-PHY with UFS host controller, the controller node should
-contain a phandle reference to UFS M-PHY node.
-
-Required properties for UFS M-PHY nodes:
-- compatible         : Compatible list, contains the following controller:
-                       "mediatek,mt8183-ufsphy" for ufs phy
-                       persent on MT81xx chipsets.
-- reg                : Address and length of the UFS M-PHY register set.
-- #phy-cells         : This property shall be set to 0.
-- 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. Following clocks are
-                       mandatory.
-                       "unipro": Unipro core control clock.
-                       "mp": M-PHY core control clock.
-
-Example:
-
-	ufsphy: phy@...a0000 {
-		compatible = "mediatek,mt8183-ufsphy";
-		reg = <0 0x11fa0000 0 0xc000>;
-		#phy-cells = <0>;
-
-		clocks = <&infracfg_ao INFRACFG_AO_UNIPRO_SCK_CG>,
-			 <&infracfg_ao INFRACFG_AO_UFS_MP_SAP_BCLK_CG>;
-		clock-names = "unipro", "mp";
-	};
-
-	ufshci@...70000 {
-		...
-		phys = <&ufsphy>;
-	};
