-Socionext EVEA - UniPhier SoC internal codec driver
-
-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
