Kernel-4.18.0-80.el8_uniphier,aio

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>;
};
