Subject: [PATCH 00/22] gpio: cdev: add uAPI V2
Date: Tue, 23 Jun 2020 12:00:45 +0800	[thread overview]
Message-ID: <20200623040107.22270-1-warthog618@gmail.com> (raw)

This patchset defines and implements adds a new version of the
GPIO CDEV uAPI to address existing 32/64bit alignment issues, add
support for debounce and event sequence numbers, and provide some
future proofing by adding padding reserved for future use.

The series can be partitioned into three sets; the first twelve
are minor code tidy ups or fixes that I ran across while implementing V2,
the next seven contain the V2 uAPI implementation proper, and the final
three port the GPIO tools to the V2 uAPI.

The more complicated patches include their own commentary where appropriate.

Cheers,
Kent.
