The X-Powers AXP20X and AXP22X PMICs have an AC entry to supply power to the board. They have a few registers dedicated to the status of the AC power supply. This adds the DT binding documentation for the AC power supply for AXP20X and AXP22X PMICs.

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";
|
|
};
|
|
};
