Subject: Re: [PATCH v2] power: supply: add dock type

Hi Sebastian,

Currently, power_supply framework supports only Battery, UPS,
Mains, USB and WIRELESS power_supply_type. Add dock
power_supply_type so that the drivers which supports dock can
register a power supply class device with POWER_SUPPLY_TYPE_DOCK.

v2: updates to Documentation

Thanks!
Jack
