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
