[PATCH 2/3] ASoC: qcom: apq8016-sbc: set default mclk rate
From: srinivas . kandagatla
Date: Mon Jul 17 2017 - 09:54:41 EST
From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx>
MCLK for internal audio codec is expected to be at 9.6MHz by default.
This patch adds support to 9.6MHz to make the default case possible.
