Incidentally I have just had an idea for a new driver-level API that
should let us do this much easier. I hope to find some time in the
next few days to come up with draft kernel patches. If you don't hear
back from me soon but want to work on validating the drivers against
the bindings, please contact me again.

The basic idea is to extend 'devres' to automatically register
all the resources (registers, irq, dma, gpio, pinctrl, clk, regulator, ...)
and simple properties before the ->probe() callback is even called,
based on a per-driver data structure that describes them, and that
can be easily parsed by an external tool.
