[alsa-devel] [PATCH v3 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 v2: - added cic selection to dapm route 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: add CIC filter source selection path sound/soc/codecs/msm8916-wcd-digital.c | 35 ++++++++++++++++++++++++++++++++-- sound/soc/qcom/apq8016_sbc.c | 23 ++++++++++++++++++---- 2 files changed, 52 insertions(+), 6 deletions(-) -- 2.9.3
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.

The patch ASoC: codecs: msm8916-wcd-digital: add CIC filter source selection path has been applied to the asoc tree at git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark
