[PATCH 0/2] Some graphics enablement for the ancient rk3066 marsboard

[Heiko Stuebner]

Enable both the hdmi output as well as the Mali400-gpu.

Did this to test a patch converting the rk3066-hdmi to a bridge driver,
for future improvements, so it'll be nice to keep this around too.

[PATCH 1/2] ARM: dts: rockchip: enable hdmi on rk3066 marsboard

[Heiko Stuebner]

The marsboard does have a regular hdmi-a connector and can simply
use the already existing infrastructure (rk3066-hdmi) for display
output.

[PATCH 2/2] ARM: dts: rockchip: enable Mali gpu on rk3066 marsboard

[Heiko Stuebner]

The rk3066 contains a Mali400 GPU, so enable it.

There is no individual (or even controllable) supply for the GPU
on the board.
