The initial plan was to merge the PWM extension API in PR #10533 first. If you take a look to the test application you can see that PWM extender channels could be used exactly like MCU pwm channels when the module `extend_pwm` is enabled what would be pretty cool. Unfortunately, we still can't find and agreement for extension APIs. But, if module `extend_pwm` is not enabled, it can be used with current interface.

That is, you could checkout the PR and you could use it. I will rebase it later today to the current master. I could also remove the extender parts for the moment, if it helps to merge it. It would be great, if you would test it.
