Subject: [PATCH v5 4/4] ARM: dts: armada-xp: Use pwm-fan rather than gpio-fan
Date: Sun,  9 Apr 2017 20:09:30 +0200	[thread overview]
Message-ID: <20170409180931.4884-5-ralph.sennhauser@gmail.com> (raw)
In-Reply-To: <20170409180931.4884-1-ralph.sennhauser@gmail.com>

From: Andrew Lunn <andrew@lunn.ch>

The mvebu GPIO driver can also perform PWM on some pins. Use the pwm-fan
driver to control the fan of the WRT1900AC, giving us finer grained control
over its speed and hence noise.
