Can you add a more specific model number for the soc as well?
I assume that cygnus refers to more than one model, so you
should probably list both the family and the individual
SoC type here.
Add specific model numbers does not seem necessary because they are not needed to be specified in the device tree for compatible purposes for the kernel to work. Plus, the list of model numbers will continue to grow over time and compatible strings would need to be added to the kernel for no apparent reason?

+Boards variants shall have the following additional properties:
+Required root node property for the BCM911360_ENTPHN board:

We normally don't list specific boards here, since it's hard to
keep up.
Thanks - removed specific boards from file and moved the cygnus.txt file to devicetree/bindings/arm/bcm/cygnus.txt in next version. This seems to be like the appropriate place to put this document. We will need to add back in board specific bindings when ALSA support is added. But that will be a later commit to deal with.
