Hello Krzysztof,

Thanks a lot for the feedback.

The story is that in v9 I split the series to add the max77802 clock and
regulators support as different series to avoid the cross subsystem churn:

[PATCH v9 0/6] Add Maxim 77802 clocks support
https://lwn.net/Articles/608834/

[PATCH v9 0/2] Add Maxim 77802 regulator support
https://lkml.org/lkml/2014/8/18/71

But then forgot to add the common DT binding for the PMIC in bindings/mfd...

right, thanks for pointing out this. It is a copy & paste error. I'll wait a
couple of days for more feedback and re-post.
