Subject: [PATCH] Asoc: qcom: lpass-cpu: Enable MI2S BCLK and LRCLK together
Date:   Fri, 18 Sep 2020 22:24:33 +0530
Message-Id: <1600448073-6709-1-git-send-email-srivasam@codeaurora.org>
Precedence: bulk

From: vsujithk <vsujithk@codeaurora.org>

Update lpass-cpu.c to enable I2S BCLK and LRCLK together.
Remove BCLK enable in lpass_cpu_daiops_startup and
add in lpass_cpu_daiops_trigger API.
