Good morning,
I need to write a device driver using several GPIO (bus of 18bits) but the IO's are not contiguous (ex: IO24, 32, 35,126 ...). I don't have a clear picture yet on how to do that (perhaps I need to declare a platform_device) but I don't want to request the GPIO's one by one, I'm guessing there must be a way to write 18bits in one shot.
Can someone help me on that, any information, source code or website will be appreciated.
Thank you very much.
