If we accept this it needs an _available as well + a list of the possible modes. That list must be exhaustive across all devices so we constrain these appropriately. However, right now this seems more like picking a trigger, or potentially the PWM feeds into the spi offload code than anything else, so I'm not sure we want to introduce new ABI for it. Jonathan >
