X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=00343e18f2fb16cf0e12f2dcd8671f7ee0aa2c8e;p=openwrt%2Fstaging%2Fynezz.git

ramips: fix PWM pin mux conflict in dtsi

GPIO18 and GPIO19 on OMEGA2(+) should be GPIO mode, enable PWM lead to a conflict

[    0.290633] rt2880-pinmux pinctrl: pin io18 already requested by pinctrl; cannot claim for 10005000.pwm
[    0.299722] rt2880-pinmux pinctrl: pin-18 (10005000.pwm) status -22
[    0.305729] rt2880-pinmux pinctrl: could not request pin 18 (io18) from group pwm0  on device rt2880-pinmux
[    0.315131] mtk-pwm 10005000.pwm: Error applying setting, reverse things back

Keep PWM disabled.
