You shouldn't normally have to define these. Why are they needed?

Maybe it's better to wait for a user to show up, and then we can decide
whether we actually want to have them this way, or if there is a better
solution for the particular use case.

Normally, we'd want to make run-time decisions based on properties
of the nodes a driver is working on, not the global machine compatible
string.

Yeah, actually this can be dropped. There is no user for it now.

OK applying all but the last patch into omap-for-v3.16/dt branch,
it seems there's no need to separate out the fixes in this case.

Tony
