I don't think both of these PIT things need to have different binding
files. 90% of it is the same, just the clock-names/number - so you can
combine the two into one file with an
allOf:
  - if:
     property:
       compatible:
         contains:
	   const: foo
    then:

    else:

type of construct.
Gimmie a shout tomorrow if you need a hand w/ it.

Thanks,
Conor.
