The ARM Mali Midgard GPU kernel driver is only available
out-of-tree and is not going to be merged in its current form.
However, it would be useful to have its device tree bindings
merged. In particular, this would enable distributions to create
working driver packages (dkms...) without having to patch the
kernel.

The bindings for the earlier Mali Utgard GPU family have already
been merged, so this is essentially the same scenario but for
newer GPUs (Mali-T604 ~ Mali-T880).

This series of patches first imports the bindings from the latest
driver release with some clean-up then adds a gpu node for the
rk3288 SoC. This was successfully tested on Radxa Rock2 Square,
Firefly, Veyron Minnie and Jerry boards using Mali kernel driver
r16p0 and r12p0 user-space binary.
I won't suggest such combine. We meet some problems at mali 400 serial.
I would suggest the kernel version would match the user library.
Also please notice there is rk3288w, the hardware version becomes r1p0.

The actual devicetree parts are all Rockchip-specific, so I guess I'll just
pick up the whole series, including the binding doc, after the merge
window if nobody complains before that :-)
