[PATCH] ASoC: rockchip: Use dummy_dai for rt5514 dsp dailink

From: Jeffy Chen
Date: Tue Nov 21 2017 - 03:25:17 EST


The rt5514 dsp captures pcm data through spi directly, so we should not
use rockchip-i2s as it's cpu dai like other codecs.

Use dummy_dai for rt5514 dsp dailink to make voice wakeup work again.
