This compatible is not documented and is not used in any driver. Is that
really working?

At the moment I send this patch another driver patch was send
to used this device tree bindings and also to document it.
Meanwhile you reviewed also that other patch.

Please let me know if you want to send again this DT patch since
I didn't yet receive any inputs its v2.

Yes, I received that patch first, without the other ones. You should
have put everything in the same series.

I'll take it once the pwm patch are taken by Thierry because it is not
useful as-is, unless you use:
 compatible = "atmel,sama5d2-pwm", "atmel,sama5d3-pwm";
