Subject: ASoC: fsl: remove use of imx-pcm-audio from imx-ssi
X-Git-Tag: v3.11-rc4~4^2~3^2~1^2~23^2~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3b7d46380beae3de4a0f03ba4dcbd509c97ab503;p=profile%2Fivi%2Fkernel-x86-ivi.git

ASoC: fsl: remove use of imx-pcm-audio from imx-ssi

Rather than instantiating imx-pcm-audio to call imx_pcm_dma_init(),
imx-ssi can just directly call it to save the use of imx-pcm-audio.
With this change, imx-ssi becomes not only a cpu DAI but also a
platform device, so updates platform device setup in imx-mc13783 and
mx27vis-aic32x4 accordingly.
