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@11fa0000 { 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@11270000 { ... phys = <&ufsphy>; };
