Subject: [PATCH v2 0/2] hwmon: (adt7475) duty cycle configuration
Date: Thu, 9 May 2024 09:55:02 +1200 [thread overview]
Message-ID: <20240508215504.300580-1-chris.packham@alliedtelesis.co.nz> (raw)
I have a system that has very over spec'd fans so the amount of noise when they
run at 100% duty cycle is considerable. We have userspace monitoring tools that
will configure appropriate fan control parameters but there is a bit of a delay
between the kernel loading the driver and the userland tools catching up to
configure the fan control. This series adds device properties that allow the
PWM duty cycle to be specified via device properties so the PWM duty cycle can
be reduced as soon as possible.
Apologies for sending the quick v2 but the v1 I sent was an earlier local
iteration than what I meant to send out.
