This bit of the commit message is no longer accurate.

The physical display tied to the framebuffer may have regulators providing power to it, such as power for LCDs or interface conversion chips. The number of regulators in use may vary, but the regulator supply binding can not be a list. Work around this by adding a "num-supplies" property to communicate the number of supplies, and a list of 0 ~ N "vinN-supply" properties for the actual regulator supply.
