Dialog Semiconductor DA9150 IIO GPADC bindings
Required properties:
- compatible: "dlg,da9150-gpadc" for DA9150 IIO GPADC
- #io-channel-cells: Should be set to <1>
(See Documentation/devicetree/bindings/iio/iio-bindings.txt for further info)
For further information on GPADC channels, see device datasheet.
Example:
gpadc: da9150-gpadc {
compatible = "dlg,da9150-gpadc";
#io-channel-cells = <1>;

Dialog Semiconductor DA9150 Charger Power Supply bindings
Required properties:
- compatible: "dlg,da9150-charger" for DA9150 Charger Power Supply
Optional properties:
- io-channels: List of phandle and IIO specifier pairs
- io-channel-names: List of channel names used by charger
["CHAN_IBUS", "CHAN_VBUS", "CHAN_TJUNC", "CHAN_VBAT"]
(See Documentation/devicetree/bindings/iio/iio-bindings.txt for further info)
Example:
da9150-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";

Generic SYSCON mapped register poweroff driver
This is a generic poweroff driver using syscon to map the poweroff register.
The poweroff is generally performed with a write to the poweroff register
defined by the register map pointed by syscon reference plus the offset
with the mask defined in the poweroff node.
Required properties:
- compatible: should contain "syscon-poweroff"
- regmap: this is phandle to the register map node
- offset: offset in the register map for the poweroff register (in bytes)
- mask: the poweroff value written to the poweroff register (32 bit access)
Default will be little endian mode, 32 bit access only.
Examples:
poweroff {
compatible = "syscon-poweroff";
regmap = <&regmapnode>;
offset = <0x0>;
mask = <0x7a>;
};
