Hello Paul,

I've looked into the driver and device-tree for judyln, I think there is 
at least missing support for two labibb supplies. This DDIC driver thus 
should have at least 2 regulators (maybe three?).

This implies:
 - driver needs to enable regulators to work properly (if you don't 
workaround it with `regulator-always-on`, which isn't right)
 - this driver is unlikely handled by simple panel
