- Raspberry Pi Compute Module

This seems sane to me. One thing I should have asked: What compatible
values does the RPi Foundation's downstream for all these cases?

good point. Unfortunately my patches to linux-rpi-kernel are held back because
of too many recipients, so it's possible that someone complain later.

I have looked at chapter 3.1 in [1], but didn't find the any other variants than
B and B+:

Here, the presence or absence of the "-plus" is the significant thing, not the
"b" -- Model A's and A+'s will
use the "b" and "b-plus" variants, respectively.

Also in the newest branch [2]:

bcm2835-rpi-b.dts -> model = Raspberry Pi Model B
bcm2708-rpi-b.dts -> model = Raspberry Pi Model B
bcm2708-rpi-b-plus.dts -> model = Raspberry Pi Model B+

Sorry, i don't have any experience with the downstream kernel. So please correct
me if looked at the wrong places.

This all matches what I found. I think differentiating between A/B and A+/B+ makes sense, so the compatible values in your patch should be fine; I'll reply to v2 in just a minute.
