     * 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";
            };
