-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>;
- };
