Subject: [PATCH v2] platform/x86: ideapad-laptop: switch platform profiles using thermal management key
Date: Wed, 3 Apr 2024 22:23:15 +0200 [thread overview]
Message-ID: <797884d8cab030d3a2b656dba67f3c423cc58be7.1712174794.git.soyer@irl.hu> (raw)
Ideapad laptops have thermal management or performance mode switch key
(Fn + Q). Now it sends KEY_PROG4.
If supported, switch platform profiles instead.
Tested on Yoga7 14ARB7.
Signed-off-by: Gergo Koteles <soyer@irl.hu>

Changes in v2:
- only switch platform profiles if supported, otherwise keep the
behavior.
