There are also devm_* versions of these functions which release the

MFD devices
~~~~~~~~~~~
The MFD devices register their children as platform devices. For the child
devices there needs to be an ACPI handle that they can use to reference
parts of the ACPI namespace that relate to them. In the Linux MFD subsystem
we provide two ways:
o The children share the parent ACPI handle.
o The MFD cell can specify the ACPI id of the device.
For the first case, the MFD drivers do not need to do anything. The
resulting child platform device will have its ACPI_COMPANION() set to point
to the parent device.
If the ACPI namespace has a device that we can match using an ACPI id,
the id should be set like:
static struct mfd_cell my_subdevice_cell = {
.name = "my_subdevice",
/* set the resources relative to the parent */
.acpi_pnpid = "XYZ0001",
};
The ACPI id "XYZ0001" is then used to lookup an ACPI device directly under
the MFD device and if found, that ACPI companion device is bound to the
resulting child platform device.

Qualcomm SPMI PMICs multi-function device bindings
The Qualcomm SPMI series presently includes PM8941, PM8841 and PMA8084
PMICs. These PMICs use a QPNP scheme through SPMI interface.
QPNP is effectively a partitioning scheme for dividing the SPMI extended
register space up into logical pieces, and set of fixed register
locations/definitions within these regions, with some of these regions
specifically used for interrupt handling.
The QPNP PMICs are used with the Qualcomm Snapdragon series SoCs, and are
interfaced to the chip via the SPMI (System Power Management Interface) bus.
Support for multiple independent functions are implemented by splitting the
16-bit SPMI slave address space into 256 smaller fixed-size regions, 256 bytes
each. A function can consume one or more of these fixed-size register regions.
Required properties:
- compatible: Should contain one of:
"qcom,pm8941"
"qcom,pm8841"
"qcom,pma8084"
or generalized "qcom,spmi-pmic".
- reg: Specifies the SPMI USID slave address for this device.
For more information see:
Documentation/devicetree/bindings/spmi/spmi.txt
Required properties for peripheral child nodes:
- compatible: Should contain "qcom,xxx", where "xxx" is a peripheral name.
Optional properties for peripheral child nodes:
- interrupts: Interrupts are specified as a 4-tuple. For more information
see:
Documentation/devicetree/bindings/spmi/qcom,spmi-pmic-arb.txt
- interrupt-names: Corresponding interrupt name to the interrupts property
Each child node of SPMI slave id represents a function of the PMIC. In the
example below the rtc device node represents a peripheral of pm8941
SID = 0. The regulator device node represents a peripheral of pm8941 SID = 1.
Example:
spmi {
compatible = "qcom,spmi-pmic-arb";
pm8941@0 {
compatible = "qcom,pm8941", "qcom,spmi-pmic";
reg = <0x0 SPMI_USID>;
rtc {
compatible = "qcom,rtc";
interrupts = <0x0 0x61 0x1 IRQ_TYPE_EDGE_RISING>;
interrupt-names = "alarm";
};
};
pm8941@1 {
compatible = "qcom,pm8941", "qcom,spmi-pmic";
reg = <0x1 SPMI_USID>;
regulator {
compatible = "qcom,regulator";
regulator-name = "8941_boost";
};
