-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>;
- };
