PWM on Odroid C2 - enable0, duty0 missing

Greeting to all,
I would like to use the hardware PWMs available in C2, however pwm-meson module is not there. It should configured as module in the kernel (as per https://github.com/CoreELEC/CoreELEC/commit/b4b49ee67483ee9e95efceddce2f2dc652e755de). And I found it mentioned also in DTB.

I can see directory in sysfs:

/sys/devices/pwm-ctrl.20

But the files enable0, duty0, etc. are not there.

What should I do to enable it?

Thanks in advance,
stay safe!
