The etnaviv kernel driver supports the i.MX8MQ GC7000 GPU. MX8QM will
require an addition to the HW database.
There are still some additions needed to the UAPI, to enable proper
support for the texture descriptor feature, which I hope to get around
to send out during this week. As those don't have an influence on the
DT nodes and things are running well in my setup, I figured the DT
patches are ready to be merged.
