Merge branch 'etnaviv/next' of https://git.pengutronix.de/git/lst/linux into drm-next
So what we have for this cycle is a bit of spring cleaning with removal
of unused register logging code and getting rid of the license text in
favor of SPDX, a few smaller MMU handling improvements and a timeout
calculation change, fixing premature fence wait timeouts after 50 days
of uptime.
