mvebu: fix portability issues in the image makefile code
[openwrt/openwrt.git] / target / linux / mvebu / patches-4.1 / 206-mvebu_wrt1900ac_use_pwm-fan_rather_than_gpio-fan.patch
1 The mvebu gpio driver can also perform PWM on some pins. Us the
2 pwm-fan driver to control the fan of the WRT1900AC, giving us fine
3 grain control over its speed and hence noise.
