To simplify identifying the pins where the PWM output is routed to, add a comment to each PWM device about the respective pin on the expansion connector.

Good idea. Some lines exceed the 100 char. I could remove "function" or only keep "func" instead. What do u think ?
Note also that commit should be: "ARM: dts: stm32: ....". i can fix it by myself.
