[Letux-kernel] AESS driver

[H. Nikolaus Schaller]

Hi,
Marek has updated and fixed some issues in the work pioneered
by Andrey and I have rebased it on top of linus/v4.18-rc2.

Here is the result:

	http://git.goldelico.com/?p=letux-kernel.git;a=shortlog;h=refs/heads/work/andrey/aess

I have not tried to test and it is not yet merged into our alpha-version
letux-4.18-rc2 but that can easily be done manually:

	git checkout -B letux+aess origin/letux-4.18-rc2
	git merge origin/work/andrey/aess

If that has no negative side-effects, we can integrate it into
the merge process of all future Letux kernels.

Next I think we have to test it and learn how to use it.

I, for example, have no idea how to configure or which
additional BLOBs are needed so that aplay works with AESS...

@Andrey: most patches from you are missing a signed-off
which makes it impossible to upstream, despite being GPL
and open source. For Letux OS we are not that strict,
especially for experimental features, but we should consider
trying to get it upstream (although it might be difficult
for other reasons for AESS).

BR an thanks,
Nikolaus
