What does the extra "ocores" suffix add, when it just repeats the vendor
prefix?

> + - starfive,jh71x0-pwm

Krzysztof, did you approve this generic compatible?

And the whole thing looks like it should really be something like

items:
- enum:
- starfive,jh7100-pwm
- starfive,jh7110-pwm
- const: opencores,pwm

Cheers,
Conor.

(assuming that the opencores,pwm compatible represents a subset of what
is implemented on the jh7100 series)

NAK. This is not something which received my review.

Patch was quite different than reviewed by me. This obviously does not
make any sense. Thanks for spotting.

I guess carrying tags should not be trusted.

This is my mistake. After making extensive changes, the tag should have been deleted
