Audio Binding for Arndale boards
Required properties:
- compatible : Can be the following,
"samsung,arndale-rt5631"
- samsung,audio-cpu: The phandle of the Samsung I2S controller
- samsung,audio-codec: The phandle of the audio codec
Optional:
- samsung,model: The name of the sound-card
Arndale Boards has many audio daughter cards, one of them is
rt5631/alc5631. Below example shows audio bindings for rt5631/
alc5631 based codec.
Example:
sound {
compatible = "samsung,arndale-rt5631";
samsung,audio-cpu = <&i2s0>
samsung,audio-codec = <&rt5631>;
};

- samsung,s3c6410-i2s: for 8/16/24bit stereo I2S.
- samsung,s5pv210-i2s: for 8/16/24bit multichannel(5.1) I2S with
secondary fifo, s/w reset control and internal mux for root clk src.
- samsung,exynos5420-i2s: for 8/16/24bit multichannel(7.1) I2S with
secondary fifo, s/w reset control, internal mux for root clk src and
TDM support. TDM (Time division multiplexing) is to allow transfer of
multiple channel audio data on single data line.
- samsung,exynos5420-i2s: for 8/16/24bit multichannel(5.1) I2S for
playback, sterio channel capture, secondary fifo using internal
or external dma, s/w reset control, internal mux for root clk src
and 7.1 channel TDM support for playback. TDM (Time division multiplexing)
is to allow transfer of multiple channel audio data on single data line.
- samsung,exynos7-i2s: with all the available features of exynos5 i2s,
exynos7 I2S has 7.1 channel TDM support for capture, secondary fifo
with only external dma and more no.of root clk sampling frequencies.
- samsung,exynos7-i2s1: I2S1 on previous samsung platforms supports
stereo channels. exynos7 i2s1 upgraded to 5.1 multichannel with
slightly modified bit offsets.
- reg: physical base address of the controller and length of memory mapped
region.
