[alsa-devel] Applied "ASoC: wm_adsp: Remove duplicate set of kcontrol->iface" to the asoc tree
by Mark Brown 05 Oct '16

05 Oct '16

The patch ASoC: wm_adsp: Remove duplicate set of kcontrol->iface 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.

[alsa-devel] [PATCH 0/6] Arizona FLL fixes and Clocking Improvements
by Charles Keepax 04 Oct '16

04 Oct '16

Hi, The first 3 patches in this series fix some small issues with the FLL configuration in the driver. The second 3 patches add support for requesting the input clocks for the CODEC through the clock framework. This is some what of an intermediate step until all the clocking itself in the CODEC can be brought under the clock framework but as there are machine drivers that want to be merged now with source clocks that require gating and difficult to resolve issues between the SPI and clock framework an intermediate solution seems warranted. Whilst the two halfs of this series do fairly different things, I have sent them as once series as they touch a lot of the same code, so this seemed the simpler approach to pushing them both through. The series is based of Mark's ASoC for-next tree. Thanks, Charles Charles Keepax (5): ASoC: arizona: Correct handling of FLL theta in synchroniser mode ASoC: arizona: Allow specification of base for arizona_is_enabled_fll ASoC: arizona: Avoid changing SYNC_ENA whilst the FLL_ENA is set ASoC: arizona: Add gating for clock when used for direct MCLK ASoC: arizona: Add gating for source clocks of the FLLs Sylwester Nawrocki (1): mfd: arizona: Add gating of external MCLKn clocks drivers/mfd/arizona-core.c | 30 +++++++++- include/linux/mfd/arizona/core.h | 9 +++ sound/soc/codecs/arizona.c | 124 +++++++++++++++++++++++++++++++++++---- sound/soc/codecs/arizona.h | 2 + sound/soc/codecs/cs47l24.c | 6 +- sound/soc/codecs/wm5102.c | 9 ++- sound/soc/codecs/wm5110.c | 10 +++- sound/soc/codecs/wm8997.c | 9 ++- sound/soc/codecs/wm8998.c | 6 +- 9 files changed, 179 insertions(+), 26 deletions(-) -- 2.1.4

[alsa-devel] [PATCH 1/2] ASoC: wm9712: Convert to regmap
by Lars-Peter Clausen 04 Oct '16

04 Oct '16

Currently the wm9712 driver still uses custom snd_soc_codec_driver IO callbacks. This has been deprecated for a while, so convert the wm9712 driver to use regmap for its IO.

[alsa-devel] [PATCH] ASoC: da7219: Improve pop/click performance for sensitive HPs

Currently on some headsets slight pops can be heard during DAPM power-up/down. This can also be witnessed during the HP detect procedure. This patch addresses the issue by adjusting DAPM power sequencing slightly, the introduction of delays and use of minimum HP gain to avoid such noise artefacts.
