This series adds a "scope" attribute to power supplies, to indicate
whether it powers the whole system ("System") or just some subset of
the devices ("Device"). This allows upowerd to distinguish between
system-wide power supplies and self-powered devices such as cordless
mice.
This series also adds a "powers" link to power supplies, so that if
they're scope=Device, they can specifically indicate which device
tree they power.
Updates since last post:
- Add more complete documentation to scope and "powers" links
- Remove unnecessary scopes on System power supplies
- Make HID battery supplies Device, and add "powers" pointers
for them.
