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,
