Interesting. So you have vendor registers outside of MMS 10-15?

Or do you need to access standard registers? I would prefer to see
your use cases before deciding this. If you want to access standard
registers, you are probably doing stuff other vendors also want to do,
so we should add a helper in the framework.

I would say no, not at the moment.

What we can do in the future is allow a driver to register a function
to handle the vendor interrupts, leaving the framework to handle the
standard interrupts, and chain into the specific driver vendor
interrupt handler when a vendor interrupt it indicated.

Please explain what you are doing here? What are you doing which the
framework does not cover.
