[PATCH 0/2] Documentation: gpio: clarify that line values are logical

[Kent Gibson <warthog618@xxxxxxxxx>]

The line values passed by the GPIO uAPI are logical values, and the edges
returned are based on changes to logical line values.  While the
documentation consistently uses active/inactive terminology to identify
the values as logical, this is never explicitly spelt out.
This series clarifies those points, with paricular emphasis on the
effect the active low flag has on values and edge polarity.

Patch 1 provides clarification for ioctls passing line values.

Patch 2 provides clarification for functions returning edge events.

Cheers,
Kent.
