Subject: [PATCH v4 0/3] Driver for UCS1002


Everyone:

This small series adds a driver for UCS1002 Programmable USB Port
Power Controller with Charger Emulation. See [page] for product page
and [datasheet] for device dataseet. Hopefully each individual patch
is self explanatory.

Note that this series is a revival of the upstreaming effort by Enric
Balletbo Serra last version of which can be found at [original-effort]

Feedback is welcome!

Thanks,
Andrey Smirnov
