88pm880 and 88pm886 are two combo PMIC chips, most of the function and the
register mapping are the same

How do they compare to 80x/822/860 PMICs?

The 80x/860 binding needs the same property. Please coordinate this
with Vaibhav.

Zhang,

Sorry, I missed this patch-series.

Is there any way we can get access to datahsheets of all these devices?

Hi, Rob:

88pm80x/822/860 and 88pm886/88pm880 are two different series:
- the register mapping is totally different, it's hard to reuse the
  existed code for 88pm80x
- the latter is a chip which integrates the charger/fuelgauge/camera
  flash which doesn't exist in 88pm80x

  Hi, Vaibhav:

  https://extranet.marvell.com/ is a useful place to access to them

+Marvell 88pm88x combo PMIC chip
+
+This series of chip integrates regulator, rtc, onkey, switch charger,
+fuelgauge, gpadc and a range of I/O pins.
+
+88pm886 and 88pm880 are two very similar chips, most of the registers mapping
+and functions are the same, the main difference is the latter has a separate
+i2c slave address to cover BUCK related setting
+
+Required properties:
+- compatible: one of the strings for a specific chip:
+  "marvell,88pm886"
+  "marvell,88pm880"
+- reg: the i2c address
+- interrupt-controller: it works as an interrupt controller managing its irqs
+- interrupt-cells: this value is 1
+
+Optional properties:
+- marvell,88pm88x-irq-write-clear: the interrupt ack method
+
+
+Example:
+
+	pmic: 88pm886@30 {
+		compatible = "marvell,88pm886";
+		reg = <0x30>;
+		interrupts = <0 4 IRQ_TYPE_LEVEL_HIGH>;
+		interrupt-parent = <&gic>;
+		interrupt-controller;
+		#interrupt-cells = <1>;
