Hi Frédéric

AFAIK, we haven't discussed yet whether we should add *pin* descriptions to the 
I/O header files. This would be a big task because it has to be done on all of 
the header files, and for all the various pin names, for it to be useful. And 
it would have to be automated in the future.

At this point, you'll just have to define those yourself for your project. 
Unless you're willing to provide a patch to implement it as described above.
