Should we encode it > in the binding? Not sure how to encode either one or the other property being required, but not both at once. Maybe I can add a supply-vibrator compatible to the driver and binding and make requirements dependent on the compatible? > Also, in the dirver code, I guess we need to switch to have regulator > optional (so we are not given the dummy one) and bail if neither > regulator nor GPIO is found. Though nothing bad will happen in the driver if binding will lack both of these. The driver will just not control any HW, so at least it's failsafe as is. regards, o. > Thanks. > > -- > Dmitry
