X-Git-Tag: MMI-PSA29.97-13-9~4589^2~44^2~2^2 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6512dd4dcf640412637ece8a412e83c3a0046d2f;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git ASoC: Intel: Use MCLK instead of BLCK as the sysclock for RT5514 codec on kabylake platform This patch fixes the pop noise in dmic recording using rt5514 on kabylake platform. This patch enables the rt5514 to use MCLK instead of BLCK as the sysclock which fixes the pop noise.
