Not so sure about that - what about requesting GPIOs for a bidirectional bus? Thinking about SPI bitbanging here.
Wouldn't you want to use a different means that the gpiod_array_*() API to handle those cases? gpiod_array_*() is probably most useful to handle bulk operations on a set of GPIOs that do essentially the same thing. If you get and then need to index into that array to handle them all differently then you don't gain very much.
For set and get, sure - but it's still useful to be able to do bulk requests for GPIOs especially since that's the only bit of the interface that requires error handling. -------------- next part -------------- A non-text attachment was scrubbed...
