Re: [alsa-devel] [RFC 06/15] ASoC: bdw-rt5677: Add a DAI link for rt5677 SPI PCM device

Hi Curtis

From: Ben Zhang benzh@chromium.org

This link is needed for the RT5677 DSP to do hotwording

If you don't need to re-use CPU/Codec/Platform definition, I guess you can use more short version?

SND_SOC_DAILINK_DEFS(dsp, DAILINK_COMP_ARRAY(COMP_CPU("spi-RT5677AA:00")), DAILINK_COMP_ARRAY(COMP_CODEC("i2c-RT5677CE:00", "rt5677-dspbuffer")), DAILINK_COMP_ARRAY(COMP_PLATFORM("spi-RT5677AA:00")));

struct snd_soc_dai_link link = { ... SND_SOC_DAILINK_REG(dsp), };
