[Mesa-dev] [PATCH v2 2/2] etnaviv: Set up unknown GC3000 states

[Wladimir J. van der Laan]

Set up new states that the blob started setting for GC3000 consistently.

This makes sure that when another test or driver leaves the GPU in
unpredictable state, these states are set up correctly for our
rendering.
