ASoC: qcom: sc7180: fix 32 bit format for adau7002 (7f2c63d6) · Commits · 戴 / test

the microphone is attached to external codec(adau7002) instead of rt5682.We need to always use 32 bit format on sc7180 to meet the clock requirement of adau7002: The ADAU7002 requires a BCLK rate that is a minimum of 64× the LRCLK sample rate Signed-off-by:
