Dialog Semiconductor DA9150 Combined Charger/Fuel-Gauge MFD bindings
DA9150 consists of a group of sub-devices:
Device Description
------ -----------
da9150-gpadc : General Purpose ADC
da9150-charger : Battery Charger
da9150-fg : Battery Fuel-Gauge
======
Required properties:
- compatible : Should be "dlg,da9150"
- reg: Specifies the I2C slave address
- interrupt-parent: Specifies the phandle of the interrupt controller to which
the IRQs from da9150 are delivered to.
- interrupts: IRQ line info for da9150 chip.
- interrupt-controller: da9150 has internal IRQs (own IRQ domain).
(See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
further information relating to interrupt properties)
Sub-devices:
- da9150-gpadc: See Documentation/devicetree/bindings/iio/adc/da9150-gpadc.txt
- da9150-charger: See Documentation/devicetree/bindings/power/da9150-charger.txt
- da9150-fg: See Documentation/devicetree/bindings/power/da9150-fg.txt
Example:
charger_fg: da9150@58 {
compatible = "dlg,da9150";
reg = <0x58>;
interrupt-parent = <&gpio6>;
interrupts = <11 IRQ_TYPE_LEVEL_LOW>;
interrupt-controller;
gpadc: da9150-gpadc {
compatible = "dlg,da9150-gpadc";
#io-channel-cells = <1>;
};
charger {
compatible = "dlg,da9150-charger";
io-channels = <&gpadc 0>,
<&gpadc 2>,
<&gpadc 8>,
<&gpadc 5>;
io-channel-names = "CHAN_IBUS",
"CHAN_VBUS",
"CHAN_TJUNC",
"CHAN_VBAT";
};
fuel-gauge {
compatible = "dlg,da9150-fuel-gauge";
dlg,update-interval = <10000>;
dlg,warn-soc-level = /bits/ 8 <15>;
dlg,crit-soc-level = /bits/ 8 <5>
};
};
