[PATCH 1/2] dt-bindings: gpu: drop wrong compatible from midgard binding example

[Heiko Stuebner]

The binding rightfully only specifies compatibles for actual implementations
and not for the whole family. In the example an arm,mali-midgard slipped
through from downstream devicetrees though. So drop that to not confuse
people reading (or copying) that example.

I'm assuming this will go thru same route arm,mali-midgard.txt got 
added.

If we remove the "arm,mali-midgard", the mali driver maybe need update 
first.

 From the lastest MALI driver on ARM supply, the compatible only two 
property.
mali_kbase_core_linux.c
4163:    { .compatible = "arm,malit6xx" },
4164:    { .compatible = "arm,mali-midgard" },

That's odd with the two compatible, the driver should support the more.

Correct, the driver should be updated anyway. In general the official
dt-binding (the one in the linux kernel) should be followed, not the random
out-of-tree one distributed by vendor drivers :-) .

If you look for example at utgard (mali400 for example), the sane binding
used in the kernel, differs a lot from the binding used by the vendor-driver
as well (io-areas, irq-names etc).

In any case, as you use the mali vendor-driver with you vendor-tree,
it should be possible to do both in sync (dt-change from mainline; driver
change to use better compatibles).
