  Add new compatible string for MT7986 PWM and list compatible units for
existing entries. Also make sure the number of pwm1-X clocks is listed
for all supported units.

I have no concerns. However converting that to yaml would be a nice
thing. Also I didn't notice an effort to adapt the dts files
accordingly. But that might be because I wasn't on Cc: for these (or I
might have missed them despite the Cc: :-)

I'll mark this patch as handled-elsewhere in the PWM patchwork.

Best regards
Uwe

Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC.  It might happen, that command when run on an older
kernel, gives you outdated entries.  Therefore please be sure you base
your patches on recent Linux kernel.

You managed to miss all folks from DT :/

Best regards,
Krzysztof
