Kent Gibson	42969726a1	Documentation: gpio: describe uAPI behaviour for unsupported config ... The existing uAPI documentation does not adequately describe how the kernel handles the case where the underlying hardware or driver does not support the requested configuration. Add a Configuration Support section describing that behaviour to both the v1 and v2 documentation, and better document the errors returned where the requested configuration cannot be supported.

Kent Gibson	32a0a0da53	Documentation: gpio: add chardev userspace API documentation ... Add documentation for the GPIO character device userspace API. Added to the userspace-api book, but also provide a link from the admin-guide book, as historically the GPIO documentation has been there.
