AXP813 AC power supply support with input current and
voltage limiting support.
AXP803 AC and battery power supply support.
Changes in v4:
* Change order of axp20x-gpio in axp20x.c
* Fix indentation and spaces to tabs in axp20x.c
Changes in v3:
* Reorder ac_power_supply DT node
* Rename axp20x_ac_power_set_property function
* Split mfd commit
Changes in v2:
* Reuse axp813 compatibles for axp803
* Refactor axp20x_ac_power.c
Oskari Lemmela (7):

Even though they seem to be compatible, please add a model specific
compatible string in front for all the new nodes just in case. In
this case it would be "x-powers,axp803-ac-power-supply".

The commit message should be more specific, like how the two connections
from the PMIC are routed. In this case ACIN is routed from the SOM to
the DC jack on the baseboard, while the battery pins are routed to a 3-pin
connector next to the USB connectors.

AXP813 and AXP803 PMICs can control input current and
minimum voltage.
Both of these values are configurable.

This doesn't handle the case where the register value is set to 0x6 or 0x7,
which should still mean 4000 mA.

Nit, don't wrap this part. Even if it exceeds the 80 character limit, it's
still easier to read that way.
