| Subject | [PATCH v6 4/4] ARM: dts: armada-xp: Use pwm-fan rather than gpio-fan |
| Message-ID | <twbDX-2Q9-5@gated-at.bofh.it> |
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.
