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 ?

I don't care much and would have expected that the line length isn't
that critical. Anyhow, shorten it to func if you prefer.

Not critical for sure. Just checkpatch that complain about it.

Note also that commit should be: "ARM: dts: stm32: ....". i can fix it by
myself.

Ack. I considered using

	ARM: dts: stm32: stm32mp135f-dk: ...

but that felt like duplicating so I dropped the "stm32" part. Feel free
to add it.

Ok thanks
