Can you please take a look at the discussion in the thread linked
below, and consider some of the approaches outlined there?

https://lore.kernel.org/all/d7794f74b26bbc1ee0a70e39c5671acc018f80eb.camel@codeconstruct.com.au/

I'd like to avoid a stream of backwards-incompatible changes due to
platform design changes where we can.
