X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=591272d197c4866b82f0ed638efe54673f2ab490;p=openwrt%2Fstaging%2Fwigyori.git

mediatek: filogic: BPi-R4: wire up pinctrl for pwm-fan

Assign pwm function of PWM0 pin to the pwm-fan.
This is mostly just cosmetics as it basically reflects the default
setting of that pin.
