I made a patch to add support for Switch 12's keyboard and tested it on Fedora 22's current 4.0.8 kernel. The patch works.

I need directions to enable hardware sleep and volume buttons on Switch 12.

Comment 1 Laura Abbott 2015-07-20 17:32:17 UTC
Glad to see you have a patch. This needs to go upstream first before we can take it into Fedora. You will probably get a faster result if you send it to the mailing list instead of posting a bugzilla, please see https://fedoraproject.org/wiki/Kernel/SubmittingUpstream as a guide.

Comment 2 Nicholas Kudriavtsev 2015-07-21 10:49:02 UTC
OK, I reported to linux-input@vger.kernel.org

Comment 3 Nicholas Kudriavtsev 2015-07-29 14:52:32 UTC
Accepted for 4.3
