> From: Koen Kooi <koen at beagleboard.org>
> TFP410 DVI chip is used to provide display out.
> This chip is controlled by 2 lines:
> LDO which supplies the power is controlled over gpio + 2
> and the enable of the chip itself is done over gpio + 1
> NOTE: the LDO is necessary for LED, serial blocks as well.
> gpio + 1 was used to sense USB overcurrent in vanilla beagle.
> Without this fix, the display would not function as the LDO
> remains shut down.
