dtbs_check would be okay though, no? The binding and dts (from checking
with eyeballs!) are consistent & it is just the driver that is looking
for the wrong property name, no?

Ulf's subsystem & his rules, but I would just send a follow-on patch
fixing the driver to use the property that is in the dt-binding.

Sorta unrelated, but please remind me about the dts patch once the base
dts is merged. It's still in the RISC-V patchwork so *should* be fine,
but in case the base dts takes a while it may get automatically
archived.

Thanks,
Conor.
