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>;
};

* ------- --------- ---------------
* 0x12000 DMAC map0 --> [selector] --> DMAC hardware 3
* 0x12080 DMAC map1 --> [selector] --> DMAC hardware 1

* rb : Ring buffer
* iport: PCM input port
* iif : Input interface
* oport: PCM output port
* oif : Output interface
* och : Output channel of DMAC for sampling rate converter
*
* These are examples for sound data paths:
*
* For caputure device:
* (outer of AIO) -> iport -> iif -> ch -> rb -> (CPU)
* For playback device:
