We now have scripts/dtc/dt-check-style. Running it over the dts with '-
-mode relaxed' yields 49 instances of 'mixed-indent-chars' - these must
be fixed. Further, can you please look at the output with '--mode
strict', address all the warnings that are reasonable, and then discuss
what's left?

Otherwise, there are still some concerns reported against the bindings:

Can you please tidy these up?
