[PATCH 0/3] ARM: dts: st: add and enable MALI400 on stih410/stih410-b2260

[Alain Volmat]

This series adds necessary node within the stih410.dtsi for
the MALI400 GPU and enable the GPU on the stih410-b2260
board.
For that purpose and since the MALI400 GPU is available on
the STi platform (stih410 / stih418), a new st,sti-mali
compatible is also added within the mali bindings.

That's quite generic compatible. I would expect here per-soc.
