Hi Sascha,

The probing looks good to me now. I would have added extra code to avoid
ioremapping the same page multiple times, but I see this as a matter of
different preferences, so I'm fine with that.

You are still missing a description of the driver, both in the changelog
above and in the Kconfig patch. A small sentence to spell out PWM
in the changelog and to list the devices that will use this driver
would be helpful to the causal reader.

Provided that you add that:

I think this hunk should have been in the other first patch.
