Subject: [PATCH v3] platform/x86: ideapad-laptop: switch platform profiles using thermal management key
Date: Thu, 4 Apr 2024 15:10:59 +0200 [thread overview]
Message-ID: <7c358ad8dd6de7889fa887954145a181501ac362.1712236099.git.soyer@irl.hu> (raw)
Ideapad laptops have thermal management or performance mode switch key
(Fn + Q). They report KEY_PROG4.
If supported, cycle platform profiles instead.
Tested on Yoga7 14ARB7.
Signed-off-by: Gergo Koteles <soyer@irl.hu>

Changes in v3:
- add dytc_profile_cycle function
Changes in v2:
- only switch platform profiles if supported, otherwise keep the
behavior.
