Hi Geert,
In general it looks just fine to me.

Hmm, phandle references are completely supported. You just have to remember
to build your base tree with the -@ option to generate the fixups :)

FWIW you’ve been CCed in the submission of the beaglebone cape-manager.
Most of the code is dealing with bone’s EEPROM format but I am sure you’ll
find stuff to cannibalize if you go to that path :)
Some people have expressed some amount of interest for basic compatibility
among extension boards that do simple low-speed I/O.
For example an expansion board that provides a few I2C peripherals should
in theory be portable between any number of boards that provide a physically
identical i2c bus.
Now how to go about doing this is a different matter altogether.

All in all, I’m happy that someone else is using this stuff, I could use the company ;)

The aliases need _path_ references.
