1MediaTek Universal Flash Storage (UFS) M-PHY binding 2-------------------------------------------------------- 3 4UFS M-PHY nodes are defined to describe on-chip UFS M-PHY hardware macro. 5Each UFS M-PHY node should have its own node. 6 7To bind UFS M-PHY with UFS host controller, the controller node should 8contain a phandle reference to UFS M-PHY node. 9 10Required properties for UFS M-PHY nodes: 11- compatible : Compatible list, contains the following controller: 12 "mediatek,mt8183-ufsphy" for ufs phy 13 persent on MT81xx chipsets. 14- reg : Address and length of the UFS M-PHY register set. 15- #phy-cells : This property shall be set to 0. 16- clocks : List of phandle and clock specifier pairs. 17- clock-names : List of clock input name strings sorted in the same 18 order as the clocks property. Following clocks are 19 mandatory. 20 "unipro": Unipro core control clock. 21 "mp": M-PHY core control clock. 22 23Example: 24 25 ufsphy: phy@11fa0000 { 26 compatible = "mediatek,mt8183-ufsphy"; 27 reg = <0 0x11fa0000 0 0xc000>; 28 #phy-cells = <0>; 29 30 clocks = <&infracfg_ao INFRACFG_AO_UNIPRO_SCK_CG>, 31 <&infracfg_ao INFRACFG_AO_UFS_MP_SAP_BCLK_CG>; 32 clock-names = "unipro", "mp"; 33 }; 34 35 ufshci@11270000 { 36 ... 37 phys = <&ufsphy>; 38 }; 39
