+* Inline Crypto Engine (ICE)
+
+Required properties:
+ - compatible : should be "qcom,ice"
+ - reg : <register mapping>
+
+Optional properties:
+ - interrupt-names : name describing the interrupts for ICE IRQ
+ - interrupts : <interrupt mapping for ICE IRQ>
+ - qcom,enable-ice-clk : should enable clocks for ICE HW
+ - 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.
+ - qcom,op-freq-hz : max clock speed sorted in the same order as the clocks
+ property.
+ - qcom,instance-type : describe the storage type for which ICE node is defined
+ currently, only "ufs" and "sdcc" are supported storage type
+ - power-domains : regulator supply to be used by ICE HW
+
+Example:
+ ufs_ice: ufsice@1d90000 {
+ compatible = "qcom,ice";
+ reg = <0x1d90000 0x8000>;
+ qcom,enable-ice-clk;
+ clock-names = "ufs_core_clk", "bus_clk",
+ "iface_clk", "ice_core_clk";
+ clocks = <&gcc GCC_UFS_PHY_AXI_CLK>,
+ <&gcc GCC_UFS_MEM_CLKREF_CLK>,
+ <&gcc GCC_UFS_PHY_AHB_CLK>,
+ <&gcc GCC_UFS_PHY_ICE_CORE_CLK>;
+ qcom,op-freq-hz = <0>, <0>, <0>, <300000000>;
+ power-domains = <&gcc UFS_PHY_GDSC>;
+ qcom,instance-type = "ufs";
+ };
