ARM: Gumstix DuoVero: Bind vdac regulator to hdmi node
PATCH 1/1 ARM: Gumstix DuoVero: Bind vdac regulator to hdmi node
The HDMI node does not have a power supply attached. As a result its power regulator, VDAC, shuts off on boot and screen loses signal. This attaches VDAC (vdda_hdmi_dac) to HDMI's vdda-supply.
