Subject: [PATCH v6 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
