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"
+
+More Required Properties for AXP20X PMICs:
+ - io-channels: phandles to ACIN voltage and current ADC channels
+ - io-channel-names = "acin_v", "acin_i";
+
+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";
+ io-channels = <&axp209_adc 0>, <&axp209_adc 1>;
+ io-channel-names = "acin_v", "acin_i";
+ };
+};
