It adds regulator support to the dumb-vga-dac bridge and enables the VGA output on the A31 Hummingbird. Changes since v3: - Add Rob's Ack. - Fix up enable/disable callbacks as Archit suggested. - Dropped pinmux settings for GPIO pin. 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".
