Both RAA228942 and RAA228943 are digital dual-output 16-Phase
(X+Y <= 16) PWM controllers. They are PMBus command compatible
with the RAA228228/RAA228244/RAA228246 family and use the same
2-rail non-TC driver configuration.

For my reference:

Reviewed-by: Guenter Roeck <linux@roeck-us.net>

Note that technically the devicetree patch should come first,
and I can not apply this and the next patch because you dropped
Krzysztof's Acked-by: tag from that patch.

Was there an Ack? I see only one reply from me, but maybe something is
lost because entire posting is completely mixed up (v2 being part of v1)
so it all appears mixed in my inbox.

Best regards,

My sincere apologies. No, there wasn't. Not a good excuse, but I got confused
with another submission.

Sorry for that.
