Yes, but it shouldn't be limited to code style quirks - I highly doubt new
contributors develop against the togreg tree of iio.git for example.

I'd propose 2 documents:
- entry profile - documenting the review cycle, patchwork, point people over to
  Sashiko, relevant git tree etc.
- code style - the TODO is fine for existing problems in the subsystem but doesn't
  point out idioms we have in IIO, i.e. not using (the awful) kernel.h, preferring
  devm_* functions, not failing on a mismatched ID to ensure fallback etc. This is
  stuff that appears a lot in patches.

Whether new contributors read these is up to them (from my experience if you write
decent docs people still won't read them and ask pointless questions), nevertheless
if we suspect someone is new we can just point them to these documents instead of
reiterating the same over and over again.
