 Required properties:
-- compatible: "x-powers,axp202" or "x-powers,axp209"
+- compatible: "x-powers,axp152", "x-powers,axp202", "x-powers,axp209",
+             "x-powers,axp221"
 - reg: The I2C slave address for the AXP chip
 - interrupt-parent: The parent interrupt controller
 - interrupts: SoC NMI / GPIO interrupt connected to the PMIC's IRQ pin
-- interrupt-controller: axp20x has its own internal IRQs
