[alsa-devel] [PATCH] ASoC: mt8173-max98090: remove the call to snd_soc_jack_add_pins.

The snd_soc_card_jack_new function can call snd_soc_jack_add_pins for you, so pass directly the pins struct when you create the new jack.

The patch ASoC: qcom: lpass-cpu: Remove unnecessary clock checks 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.

[alsa-devel] [PATCH 00/10] ASoC: add OF-graph base simple-card
by Kuninori Morimoto 31 Jan '17

Hi Mark, Rob These are OF-graph base simple-card patch-set. Unfortunately, OF-graph DT binding idea for ALSA SoC was rejected many times before. 1st OF-graph idea doesn't have card node, but because of ML discussion, latest idea can have it. OTOH, Mark doesn't like big-patch-set. Thus, some of already accepted preparation patches for OF-graph simple-card was no longer needed. 1) - 4) remove these.

[alsa-devel] License for UCM config files - re plumbers audio conf discussion.
by Liam Girdwood 31 Jan '17

31 Jan '17

During the plumbers audio conference we discussed changing the release cadence and packaging of the UCM config files. This was to separate them from the alsa-lib package and alsa-lib release cadence for easier and more timely distribution for Ubuntu, Fedora etc. One thing that we did not cover was the UCM config file licence, if indeed there is a license for the UCM config files ? It's clear to me that the alsa-lib source and headers are LGPL, but does the LGPL also apply to the runtime UCM config files ? LGPL is specifically designed for libraries so my understanding is that it's probably not applicable to the UCM runtime configuration files. Here the LGPL definition of source code from alsa-lib COPYING :- ""Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library." Having a licence free or BSD/MIT type license for the UCM config repo would mean the configurations (or derivatives of) could also be used with Android. IANAL Liam
