This does not express compatibility properly.

Looks good to me:

Acked-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

What are the merge plans here? The whole series via pwm or a samsung
tree? Or a mixture?

Best regards
Uwe

It would be nice to be merged whole series in the samsung tree.

Krzysztof could you apply all patch after your review?

Patch needs fixes - it is really different than we talked about.

Anyway, both PWM patches - bindings and driver - should go via PWM tree.
I will take the DTS, once proper version is sent.

Best regards,
Krzysztof

That's not what I asked for. You do not need entry here. Devices are
compatible.

I misunderstood your intent.

I will add only this compatible to DT and send it again with v3 patch.
