Why is vin-supply required?
The chip cannot function without VIN power supply. Even if it's on the
always-on power rail on certain board, there's always a chance it might be
accidentally left disabled on the other. It's better to document supply in
the bindings as far as I understand.
You haven't just documented the binding, you have also made the property
mandatory by adding it to required.
So what I am asking is why is this property listed as required. You
didn't implement the driver in a way that makes the supply mandatory.
