Subject: [PATCH] hwmon: (dell-smm) Also add Dell Precision 7540 to fan control whitelist
Date: Sat, 23 Dec 2023 16:36:58 +0900 [thread overview]
Message-ID: <20231223073658.354773-1-snishika@redhat.com> (raw)
This patch, in addition to 95d88d054ad9 that added Dell Precision 7510 to fan
control whitelist, also adds Precision 7540 to the whitelist, which allows manual
PWM control on Dell Precision 7540. It has been confirmed that the same SMM
commands work to enable/disable manual PWM control on Dell Precision 7540.
