sorry for the late reply, but it seems I got somehow droppen from your recipient list, so just found this mail on the mailinglist. In v1 I specified the interrupt and the gpio. Apart from the resulting duplication of information this also resulted in the gpio only being requested but never used itself, which Mark Rutland did not seem to like this much :-) . As I'd like to keep the sanity check that really requesting the interrupt gpio provides I did go this way, as the interrupt pin of the chip is of course always provided thru a gpio. As there are other drivers going this route it looked like an ok way to go. So what would be the real way to go? Specify only the interrupt, only the gpio or both?
