Is it correct to specify over-current protection for a regulator-fixed? It causes kernel messages:
[ 7.988337] vbus0: IC does not support requested over-current limits [ 7.994756] vbus0: IC does not support requested over voltage limits [ 7.998796] vbus1: IC does not support requested over-current limits ...
The reason I put the property was that the 1A limit is a property of the regulator component (NCP380-1.0A). Maybe that is the wrong property?
It also generates an interrupt for which I found no suitable description.

same here
