[alsa-devel] [PATCH 1/2] ASoC: Intel: Add Kabylake machine driver for RT5514, RT5663 and MAX98927

Harsha Priya harshapriya.n at intel.com
Tue Jun 6 22:51:32 CEST 2017


This patch adds Kabylake I2S machine driver which uses codecs
MAX98927 as speakers and RT5514 as dmic on ssp0 and
RT5663 as headset on ssp1.
