Subject: [PATCH 1/3] ASoC: codecs: msm8916-wcd-digital: add support to set_sysclk
Date: Mon, 17 Jul 2017 15:54:08 +0200	[thread overview]
Message-ID: <20170717135410.26812-2-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20170717135410.26812-1-srinivas.kandagatla@linaro.org>

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.
