The first one can be board-ctrl. The second however manages things that are
beyond this board and important for other boards in the chassis, so I think
chassis-mgmt is correct.
For the binding/compatbiles issues: in the first discussion I had omitted these
nodes because these are not available (and honestly for such FPGAs I doubt they
will ever be mainlined). We discussed it and concluded that the DTS should
describe the HW and not the drivers available in the kernel so I have now added
them. Do you want me to add the compatible strings we use in our tree even
though there are no bindings ? Leave them as is ? Or drop them ?
