It's more up to me, as I ended up being the initial author of the
mainline files - and if you look at:

http://www.home.arm.linux.org.uk/~rmk/cubox/hummingboard-cubox-i-v3.16-rc2-20140624/0041-sgtl5000-hacks.patch

you'll see the patch I refer to above, which is my own work, and it's
hardly changed to the 3.18 patch:

http://www.home.arm.linux.org.uk/~rmk/cubox/hummingboard-cubox-i-v3.18-20141216/0113-sgtl5000-hacks.patch

Well, I do now. :)

I had dropped the ball on a load of kernel stuff as it seemed to be going
nowhere, no one seemed interested in it, and my massive backlog of patches
(especially things like the ethernet driver) just became far too difficult
both to merge into mainline and to keep forward-porting.

In any case, anyone who is serious about using the SolidRun hardware runs
Jon Nettleton's fully featured kernel (which is the basis for SR's kernel)
- sadly something which mainline likely is never going to be.

It's a bit like the MMC stuff, I'm still carrying Olof's solution for
the SDIO wifi/bt power and reset control stuff, and I'm not at present
intending to do anything with it other than continue forward-porting it.
I'm not interested in wasting free time trying to re-work that to suit
some other solution, especially as people couldn't settle on a solution
when I /did/ have an interest in it (not that I have much interest in
wifi or BT - I tend to prefer old fashioned wired connections.  It also
doesn't help that the Broadcom driver seemed to be very flakey with
brcm4329 hardware for quite some time.)

Anyway, you can find all my kernel patches in a suitably trimmed version
of the above URL, and on http://ftp.arm.linux.org.uk/cgit/ is a huge pile
of effort I put into an accelerated X server with etnaviv and /my/ kernel
version of etnaviv drm, complete with Xv support.
