[alsa-devel] [PATCH 0/7] Audio support for Armada 370 DB

[Thomas Petazzoni]

Hello,

This series of patches enable audio support on the Marvell Armada 370
Development Board. Since both the I2S controller on the SoC side and
the I2C audio codec are already supported by the kernel, the amount of
work is fairly limited.

Also, since the DT bindings that allows to replace the ASoC board
driver are still being ironed out, I'm proposing to add an old-style
ASoC board driver for now.

This set of patches only provide support for the analog output and
input, I am waiting for the optical cable to arrive to get the digital
input and output to work.

Patches 1 to 3 are to be taken by the ASoC maintainer, while patches 4
to 7 are to be taken by the mvebu maintainers.

Note that the audio support for Armada 370 also needs a fix to the
CS42L51, which is being discussed with the author of the change that
apparently introduced the problem (see discussion at
http://mailman.alsa-project.org/pipermail/alsa-devel/2014-January/071916.html).

Thanks,

Thomas
