Subject: [PATCH 7/7] mvebu: wrt1900ac: Use pwm-fan rather than gpio-fan
Date: Sat, 10 Jan 2015 00:34:53 +0100 [thread overview]
Message-ID: <1420846493-31647-8-git-send-email-andrew@lunn.ch> (raw)
In-Reply-To: <1420846493-31647-1-git-send-email-andrew@lunn.ch>
The mvebu gpio driver can also perform PWM on some pins. Us the
pwm-fan driver to control the fan of the WRT1900AC, giving us fine
grain control over its speed and hence noise.
