Subject[PATCH v8 10/10] ASoC: qcom: lpass-sc7280: Add platform driver for lpass audio
Date
From: Srinivasa Rao Mandadapu <srivasam@codeaurora.org>

Add platform driver for configuring sc7280 lpass core I2S and
DMA configuration to support playback & capture to external codecs
connected over secondary MI2S interface and soundwire interface.
