[PATCH 0/2] Dove GPU support

[Lucas Stach]

Hi Dove maintainers,

those 2 patches add support for the Vivante GPU. The binding has already been
acked by the DT maintainers and is included in the pull request for the DRM
driver. I hope you can pick those patches up for inclusion in 4.5.

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.
