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.
|
|
|
|
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>;
|
|
};
