[alsa-devel] [PATCH 3.4 1/2] ASoC: wm8994: Prevent ABBA deadlock with CODEC and accdet mutexes
by Mark Brown 12 Mar '12

12 Mar '12

Currently we can the accdet mutex from within DAPM when updating the device state which means we take accdet then the CODEC mutex but we also do the locking the other way around when responding to the jackdet IRQ. Move all the jackdet use of the CODEC mutex out of the accdet lock to avoid this. Since all the DAPM interactions depend only on a single threaded IRQ this is still serialised. The locking improvements in 3.5 allow a better solution there.

The second just updates one of the pyalsa tests (apparently function names changed some time ago).

[alsa-devel] [PATCH 0/4] mc13783 sound support
by Philippe Rétornaz 12 Mar '12

12 Mar '12

Hello This is patchset enable sound support on boards with mc13783 codec. The first patch adds the codec driver. It's Sascha's code ported to the current kernel with some minors additions. The second patch adds a generic SoC platform driver for imx3 boards with mc13783 codecs. The last two patches enable the sound on the mx31moboard boards and on mx31pdk_3ds boards. This patchset has been tested on mx31moboard and mx31pdk_3ds. It is based on a 3.3-rc6 kernel. I know there are some patches which change how audmux is handled on i.Mx processor but they are not yet merged so I prefer to post this patchset based on a known tree than to add another dependency. If the audmux change is merged I will rebase this patchset. Small note: If you want to test this, make sure you use redboot as bootloader or that you have the patch i.MX 35/5 AIPS Setup applied.
