[PATCH 0/3] drm: panfrost: Coherency support

[Robin Murphy]

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.
