With /sys/class/pwm a more versatile interface to pwm exists now. e.g. configure a 1kHz 25% on PWM<C>: (period and duty cycle in nano seconds) $ cd /sys/class/pwm/pwmchip3 $ echo 0 > export $ echo 1000000 > pwm0/period $ echo 250000 > pwm0/duty_cycle $ echo 1 > pwm0/enable Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
