AXP20X and AXP22X PMICs' AC power supply
Required Properties:
- compatible: One of:
"x-powers,axp202-ac-power-supply"
"x-powers,axp221-ac-power-supply"
This node is a subnode of the axp20x PMIC.
The AXP20X can read the current current and voltage supplied by AC by
reading ADC channels from the AXP20X ADC.
The AXP22X is only able to tell if an AC power supply is present and
usable.
Example:
&axp209 {
ac_power_supply: ac-power-supply {
compatible = "x-powers,axp202-ac-power-supply";
};
};

The AXP223 PMIC shares most of its behaviour with the AXP221 but has slight
variations such as the former being able to set the VBUS power supply max
current to 100mA, unlike the latter.

- usb_otg_in-supply:
Usage: optional
Value type: <phandle>
Description: Reference to the regulator supplying power to the USB_OTG_IN
pin.
child nodes:
- otg-vbus:
Usage: optional
Description: This node defines a regulator used to control the direction
of VBUS voltage - specifically: whether to supply voltage
to VBUS for host mode operation of the OTG port, or allow
input voltage from external VBUS for charging. In the
hardware, the supply for this regulator comes from
usb_otg_in-supply.
