The only difference between TMUs is the input capture capability on the 3rd
channel in each TMU -- that includes TCPR register and extra interrupt output
TICPI<n> (perhaps has to do with 4th TMU IRQ?). The driver is blissfully unaware
of this extra capability. :-)

Yes, but they only differ in the number of channels capable of input capture.

Nohow. And I'm not sure we should care about this difference...
