+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>;
+ };
