I'd expect that the GPIO users should coordiante directly rather than rely on the GPIO API to do the coordination for them - there aren't enough semantics in the GPIO itself to do much more except possibly provide discovery services (which would be nice). Look at how the regulator API manages multiple regulators sharing an enable GPIO for example, it adds an additional layer of reference counting when it identifies a shared GPIO.
OK, it is still regulator core, though. Not individual drivers problem.
Several other existing drivers have the same issue, so this should be solved in a generic or shared way.
Indeed.
