This patch adds support for the tps65090 charger driver.
Would be nice to get a few more words about the hardware and the driver.
Why it is cool, main features, what is missing (if any), what is planned.

Yah, this is really a child driver of the tps65090 mfd chip, so a lot of the driver coolness
is already defined there :) I'll look into the hw some and see what other coolness might
be possible to add around here :)

You should request irq after power_supply object (and charger_data) are
fully usable. Otherwise, if irq suddenly comes midway in the registration
process, we'll get an oops.

Yah the first time I looked at this the order struck me as kinda off, but I guess I got
sidetracked and forgot to go back to it. Thanks for catching this!
