Instead, how about a note like this near the top of the file:

All references to "1.0" and "2.0" refer to the QorIQ chassis version to
which the chip complies.

Chassis Version		Example Chips
---------------		-------------
1.0			p4080, p5020, p5040
2.0			t4240, b4860, t1040

BTW, this binding and the associated driver really should be called
"qoriq-clock", not "corenet-clock".  This would match the compatible
string, and it doesn't really have much to do with corenet (which is
part of the QorIQ chassis v1 and v2, but not *this* part).  Do you know
if the chassis v3 clock interface will be similar enough to share a
