Hi,

This is v3 of my sun6i DRM/KMS display enablement series. Most of the
patches in v2 were merged, leaving only the dumb-vga-dac patch and the
hummingbird-a31 VGA output patch.

A few things were changed, mainly the DAC enable method from a GPIO
to a regulator supply.

Changes since v2:

  - Changed the enable-gpio of dumb-vga-dac to vdd-supply regulator.
    This better matches the hardware that I have: the DAC has a fixed
    regulator dropping the voltage from the board-wide 5V to 3.3V the
    DAC uses. The regulator is controlled through a GPIO pin.

  - Renamed the node of the VGA connector from "vga" to "vga-connector".

  - Renamed the node of the VGA DAC from "bridge" to "vga-dac".


Regards
ChenYu
