+Required properties:
+- compatible : should be "socionext,uniphier-evea".
+- reg : offset and length of the register set for the device.
+- clock-names : should include following entries:
+ "evea", "exiv"
+- clocks : a list of phandle, should contain an entry for each
+ entries in clock-names.
+- reset-names : should include following entries:
+ "evea", "exiv", "adamv"
+- resets : a list of phandle, should contain reset entries of
+ reset-names.
+- #sound-dai-cells: should be 1.
+
+Example:
+
+ codec {
+ compatible = "socionext,uniphier-evea";
+ reg = <0x57900000 0x1000>;
+ clock-names = "evea", "exiv";
+ clocks = <&sys_clk 41>, <&sys_clk 42>;
+ reset-names = "evea", "exiv", "adamv";
+ resets = <&sys_rst 41>, <&sys_rst 42>, <&adamv_rst 0>;
+ #sound-dai-cells = <1>;
