[alsa-devel] Merging alsa-driver and alsa-kmirror to one GIT repo
by Jaroslav Kysela 26 Sep '12

26 Sep '12

Hi all, I believe, it's time to manage only one GIT repository for the alsa-driver package now. The merge has benefits mainly for the end users - bisecting may work, the correlation between kernel sources and our out-of-kernel build framework becomes more strong. I merged the alsa-driver and alsa-kmirror repos with full history. I also added some code changes to enable the "build-in" mirror tree in Makefile and gitcompile from v1.0.18 (but I don't think that it will be used). The structure of new repository is similar, but the kernel mirrored code is located in the mirror/ subdirectory. The paths are exactly same as in the Linux kernel tree, so possible patches can be applied without any path modifications. Of course, we may create a bash script to do proper and full cherry-picks between kernel and mirrored trees (comments, author, dates). New temporary repository has name alsa-driver.new: http://git.alsa-project.org/?p=alsa-driver.new.git;a=summary The another difference is that the releases are now branches not tags. It allows me to do quick fixes out of the standard development or separate the main development in the release time window (to not include some very new code). The previous branches won't contain probably any additional commits, but it's probably better to play with only one reference scheme. I think that the change from alsa-driver.git to alsa-driver.new.git should be quick. Please, report any objections or acks now. Schedule: When accepted, I will rename the original alsa-driver.git repository to alsa-driver.old.git and move alsa-driver.new.git to alsa-driver.git quickly. 1.0.26 release: This was my last big change (with the ALSA server upgrade) which blocked me to do the 1.0.26 release. I'm going to create new release after the repos switch ASAP. Jaroslav -- Jaroslav Kysela <perex(a)perex.cz> Linux Kernel Sound Maintainer ALSA Project; Red Hat, Inc.

[alsa-devel] [PATCH 1/2] ASoC: fsl_ssi: Let it understand mono
by Fabio Estevam 25 Sep '12

25 Sep '12

Currently there are two variants for the FSL SSI driver: - fsl_ssi.c is the device tree driver version for the FSL SSI driver (used by PowerPC and i.MX) - imx-ssi.c is the non device tree version that runs on some i.MX processors that are not yet converted to dt. Commit 0865a7 (ASoC: imx-ssi: Remove mono support) attempted to fix mono audio playback issue inside imx-ssi.c, which according to 104c22 (ASoC: Revert 'ASoC: imx-ssi: Remove mono support' ) caused problem on another i.MX platform. The original mono playback issue was later fixed inside the mc13783 codec driver. As the long term goal is to move other platforms to dt, then fsl_ssi needs to have the same fix for channels_min as in imx-ssi.

[alsa-devel] [PATCH] ASoC: core: Configure pin muxing via pinctrl when registering a DAI
by Peter Ujfalusi 25 Sep '12

25 Sep '12

pinctrl framework now becoming widely available for SoCs to configure pin multiplexing. Instead of adding the same code to all dai drivers the core can take care of this transparently. Do not make too much noise if pinctrl is not provided via DT for the dai but just use dev_info(). Signed-off-by: Peter Ujfalusi <peter.ujfalusi(a)ti.com> --- Hi Mark, Liam, I was about to add the pinctrl support for OMAP dais (McBSP/McPDM/DMIC/HDMI) when I realized that I just kept duplicating the same code all over.
