Add support for the AXP717 PMIC to utilize the ADC (for reading
voltage, current, and temperature information from the PMIC) as well
as the USB charger and battery.

Hi Lee, patch 12 is dependent on this because of the header
additions.

If you don't mind can you pick up 1, 8 and 12
(all the IIO ones)?  Otherwise they'll have to wait for next
cycle. Guessing too late to ask for an IB?

I haven't checked but the later power supply ones may have
the same block.

Thanks,

Jonathan

Yes, patches 13 + 14 are also blocked by the MFD patch adding
register defines. I merged the other power-supply patches before
noticing this, so patches 13 + 14 need to wait a cycle without
an immutable branch.

Greetings,

Moved to an immutable branch and submitted for testing.
