[PATCH 0/2] ARM: dts: sun8i: r40: Enable mali400 GPU

[Jernej Skrabec]

Following two patches enable Mali400 GPU on Allwinner R40 SoC. At this
point I didn't add table for frequency switching because it would
require far more testing and defaults work stable and reasonably well.

Please take a look.

Best regards,
Jernej

Allwinner R40 SoC contains Mali400, so add its specific compatible to
bindings.

R40 has Mali400 GP2 GPU. Add a node for it.
