The patches don't compile yet => rebase and make them compile.

Then once I'll have it tested and cleaned up I'll send it upstream.

We also need to sync with Viciouss who is working on similar patches for the GT-N8000: https://github.com/Viciouss/linux/commit/bf6d0a67b7bdc62433c663fe4c2886af8a0af9d2

Edit 1:Fix typo and add device.

It looks like a samsung employee has been submitting midas related patches upstream, including a patch set for audio support: https://patchwork.kernel.org/project/linux-samsung-soc/list/?submitter=7616

It looks like you can test out the audio patch as of today using the sound-5.9-rc1 branch, as is explained here: https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg2260833.html

  • Target version set to Replicant 11.0 0001

Audio now works with the upstream kernel and with kernel/replicant/linux too.

Though we only have extremely basic support in Replicant userspace (only output to speakers) for now as we need to make the modem work before in order to see how to architecture the code.
