As can be seen in page 113 in the manual this component
has VDD and VDDIO supplies and sooner or later someone
is going to have to model that so I'd say add vdd-supply and
vddio-supply regulator phandles as optional to the component
already from start.

Thanks!

And interrupts too. Doesn't matter what the driver currently uses.

Will do. I plan to work on adding support for interrupts in a follow-up patchset,
but I'll add this to the devicetree documentation.
