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 > > > > > Signed-off-by: Yi Zhang <yizhang@xxxxxxxxxxx> > > --- > > Documentation/devicetree/bindings/mfd/88pm88x.txt | 33 +++++++++++++++++++++++ > > 1 file changed, 33 insertions(+) > > create mode 100644 Documentation/devicetree/bindings/mfd/88pm88x.txt > > > > diff --git a/Documentation/devicetree/bindings/mfd/88pm88x.txt b/Documentation/devicetree/bindings/mfd/88pm88x.txt > > new file mode 100644 > > index 0000000..72e741c > > --- /dev/null > > +++ b/Documentation/devicetree/bindings/mfd/88pm88x.txt > > @@ -0,0 +1,33 @@ > > +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 > > The 80x/860 binding needs the same property.
