[alsa-devel] [PATCH v2 0/3] ASoC: codecs: msm8916-wcd-digital: Fix dmic support
From: Srinivas Kandagatla srinivas.kandagatla@linaro.org
This patchset fixes dmic support in the codec driver, first and second patch fixes the mclk rate for the codec and the third patch adds missing selection of DMIC in CIC filter source path.
Tested on DB410c with Audio Mezz board which has got dmic on it.
Changes since v1: - check return values for set_sysclk and clk_set_rate() spoted by Mark. - Added more info in change log. - Fixed multicodec usecase.
Srinivas Kandagatla (3): ASoC: codecs: msm8916-wcd-digital: add support to set_sysclk ASoC: qcom: apq8016-sbc: set default mclk rate ASoC: codecs: msm8916-wcd-digital: select DMIC source in CIC filter path

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.

What happens when someone needs this filter connected somewhere else - shouldn't this be controlled as part of the DAPM routing?

There are only two paths for this, one is DMIC and other is AMIC.
Yes, its possible to add these as dapm routing, i will give it a go in next version.
