I propose that there be a discussion as to the future direction
of the GPIO userspace interface.
Here are some topics in need of discussion:
- The continued use of the sysfs interface and possible enhancements
or restructuring.
- The possibility of a char interface and its implications.
- The introduction of gpio groups to userspace.
Here are some links to various discussions on the mailing list:
