Option 1 is clearly a good approach and indeed in the context of theUnder what circumstances is adding a small sample to at least build

against the relevant APIs not possible/practical? Obviously it's not
always feasible to prove that something works correctly, especially an
external peripheral which may require some elaborate test apparatus,
but proving that something at least compiles seems trivial to me.
The trigger for this thread is pwm/dw where no board currently
supports the driver, it does not currently build but there is an
expectation that the driver will be useful in the future.
