[alsa-devel] [PATCH] ASoC: fsl: Set sdma peripheral type directly

[Nicolin Chen]

Let CPU DAI drivers set SDMA periperal type directly to support more
dma types(SPDIF, ESAI) other than only two for SSI.
This will easily allow some non-SSI drivers to use the imx-pcm-dma
as well.

Compile-passed with mpc85xx_defconfig by using gcc-4.6.3-nolibc_powerpc-linux.
