Required SoC Specific Properties:
- compatible : "samsung,i2s-v5"
- compatible : should be one of the following.
- 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.
- reg: physical base address of the controller and length of memory mapped
region.
- dmas: list of DMA controller phandle and DMA request line ordered pairs.

Optional SoC Specific Properties:
- samsung,supports-6ch: If the I2S Primary sound source has 5.1 Channel
support, this flag is enabled.
- samsung,supports-rstclr: This flag should be set if I2S software reset bit
control is required. When this flag is set I2S software reset bit will be
enabled or disabled based on need.
- samsung,supports-secdai:If I2S block has a secondary FIFO and internal DMA,
then this flag is enabled.
- samsung,idma-addr: Internal DMA register base address of the audio
sub system(used in secondary sound source).
- pinctrl-0: Should specify pin control groups used for this controller.
