Hi Patrik Please read this: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/hwmon/w83627ehf?id=refs/tags/v4.9-rc4 IIRC you need to set it to manual mode first via echo 1 > .../pwmX_enable and perhaps then it will accept your PWM values. I'm giving proper mailing list on CC, maybe someone will help.
