-Socionext UniPhier SoC audio driver
-
-The Socionext UniPhier audio subsystem consists of I2S and S/PDIF blocks in
-the same register space.
-
-Required properties:
-- compatible      : should be one of the following:
-		    "socionext,uniphier-ld11-aio"
-		    "socionext,uniphier-ld20-aio"
-		    "socionext,uniphier-pxs2-aio"
-- reg             : offset and length of the register set for the device.
-- interrupts      : should contain I2S or S/PDIF interrupt.
-- pinctrl-names   : should be "default".
-- pinctrl-0       : defined I2S signal pins for an external codec chip.
-- clock-names     : should include following entries:
-                    "aio"
-- clocks          : a list of phandle, should contain an entry for each
-                    entry in clock-names.
-- reset-names     : should include following entries:
-                    "aio"
-- resets          : a list of phandle, should contain an entry for each
-                    entry in reset-names.
-- #sound-dai-cells: should be 1.
-
-Optional properties:
-- socionext,syscon: a phandle, should contain soc-glue.
-                    The soc-glue is used for changing mode of S/PDIF signal pin
-                    to Output from Hi-Z. This property is optional if you use
-                    I2S signal pins only.
-
-Example:
-	audio {
-		compatible = "socionext,uniphier-ld20-aio";
-		reg = <0x56000000 0x80000>;
-		interrupts = <0 144 4>;
-		pinctrl-names = "default";
-		pinctrl-0 = <&pinctrl_aout>;
-		clock-names = "aio";
-		clocks = <&sys_clk 40>;
-		reset-names = "aio";
-		resets = <&sys_rst 40>;
-		#sound-dai-cells = <1>;
-
-		socionext,syscon = <&sg>;
-	};
