Subject[PATCH 1/3] ASoC: codecs: msm8916-wcd-digital: add support to set_sysclk
Date
From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch adds support to set_sysclk() which can let the sound
card driver to set default mclk rate. In this case MCLK for
internal audio codec is expected to be at 9.6MHz by default.
