Old device trees that don't specify the 3.3V rail need to keep working fine and thus it's optional (not required) for people to include the 3.3 V rail. (NOTE: in the source code things will work fine without any changes because the regulator framework will automatically create a "dummy" regulator for you if one wasn't specified in the device tree). -Doug

The auo,b101uan08.3 panel (already supported by this driver) has a 3.3V rail that needs to be turned on. For previous users of this panel this voltage was directly output by pmic. On a new user (the not-yet-upstream sc7180-trogdor-mrbland board) we need to turn the 3.3V rail on.
