-* Cadence Universal Flash Storage (UFS) Controller
-
-UFS nodes are defined to describe on-chip UFS host controllers.
-Each UFS controller instance should have its own node.
-Please see the ufshcd-pltfrm.txt for a list of all available properties.
-
-Required properties:
-- compatible : Compatible list, contains one of the following controllers:
- "cdns,ufshc" - Generic CDNS HCI,
- "cdns,ufshc-m31-16nm" - CDNS UFS HC + M31 16nm PHY
- complemented with the JEDEC version:
- "jedec,ufs-2.0"
-
-- reg : Address and length of the UFS register set.
-- interrupts : One interrupt mapping.
-- freq-table-hz : Clock frequency table.
- See the ufshcd-pltfrm.txt for details.
-- 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. "core_clk" is mandatory.
- Depending on a type of a PHY,
- the "phy_clk" clock can also be added, if needed.
-
-Example:
- ufs@fd030000 {
- compatible = "cdns,ufshc", "jedec,ufs-2.0";
- reg = <0xfd030000 0x10000>;
- interrupts = <0 1 IRQ_TYPE_LEVEL_HIGH>;
- freq-table-hz = <0 0>, <0 0>;
- clocks = <&ufs_core_clk>, <&ufs_phy_clk>;
- clock-names = "core_clk", "phy_clk";
- };
