+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 {
