I also would like help with upstreaming effort. I started some work on
integration of patches that lay here and there. I wrote blog post about
this [1]. Unfortunately since I have some embedded development
experience for x86 I still learn ARM and Linux kernel development.

Right now on github repository [2] we have mailbox API v10,
bxm2835-mbox, bcm2835-cpufreq and bcm2835-thermal (last tree from
Lubomir Rintel tree).

There is something on foundation repository on GitHub [3] and [4]. I
also try to track some things as issues in rpi-dt-linux repository.
