From 820f7541f952afa8db08ccd420f29a2c6c148709 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Wed, 2 Aug 2017 15:17:46 +0200 Subject: [PATCH] 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.
