From: Srinivas Kandagatla Date: Wed, 2 Aug 2017 13:17:46 +0000 (+0200) Subject: ASoC: codecs: msm8916-wcd-digital: add support to set_sysclk X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2032ce4de818366adb78d8e0b29291ce58ae1e40;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ASoC: codecs: msm8916-wcd-digital: add support to set_sysclk 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.
