+description: |
+  MP2629 is an PMIC providing battery charging and power supply for smartphones,
+  wireless camera and portable devices. Chip is contrlled over I2C.
+
+  The MFD device handles battery charger controller and ADC IIO device for
+  battery, system voltage
+
+properties:
+  compatible:
+    const: mps,mp2629
+
+  reg:
+    maxItems: 1
+
+  interrupts:
+    maxItems: 1
+
+  interrupt-controller: true
+
+  "#interrupt-cells":
+    const: 2
+    description:
+      The first cell is the IRQ number, the second cell is the trigger type.
+
+required:
+  - compatible
+  - reg
+  - interrupts
+  - interrupt-controller
+  - "#interrupt-cells"
