It's just an ad-hoc since there are a few independent teams are doing
something that related to fwnode APIs: Daniel due to camera work for ACPI
enabled platforms, Qian due to a design bug with fwnode, Anand due to IIO
drivers, you are due to PHY (and possibly others I have no knowledge about).

I haven't asked for the others I listed above since their work probably
doesn't cross what you are doing, but camera might be closer.
