[PATCH v2 13/14] ARM: dts: dove: add DT GPU support

Hi Lucas,

Dove maintainers,

can you please tell me if you prefer the DT changes to go along with the
rest of the etnaviv series through the DRM tree, or plan on picking this
separate?

I prefer to take the DT change in the mvebu tree. I was waiting for
acknowledgment on this series from the DRM maintainers to be sure that
the binding was OK. However, the fact that Rob Herring already acked the
binding is a good point for me.

Gregory

Regards,
Lucas

Add DT support for the Vivante GC600 GPU on Marvell Dove platforms.
These nodes default to being disabled unless a platform decides they
should be enabled.
