20 In Linux GPIO lines also have a userspace ABI.
22 The userspace ABI is intended for one-off deployments. Examples are prototypes,
24 industrial automation, PLC-type use cases, door controllers, in short a piece
26 operators to have a deep knowledge of the equipment and knows about the
27 software-hardware interface to be set up. They should not have a natural fit
28 to any existing kernel subsystem and not be a good fit for an operating system,
29 because of not being reusable or abstract enough, or involving a lot of non
32 Applications that have a good reason to use the industrial I/O (IIO) subsystem
33 from userspace will likely be a good fit for using GPIO lines from userspace as
41 The userspace ABI is a character device for each GPIO hardware unit (GPIO chip).
