Hi all,
I polished up my original proof-of-concept a little while back, but now that I've got my hands on my Juno again I've been able to actually test it to my satisfaction, so here are proper patches!
It probably makes sense for patches #1 and #2 to stay together and both go via drm-misc, provided Will's OK with that.
Robin.
