|
+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>;
|
|
+
|
|
+ marvell,88pm88x-irq-write-clear;
|
|
+ };
