+          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",
+                   "qcom,pm8019",
+                   "qcom,pm8226",
+                   "qcom,pm8110",
+                   "qcom,pma8084",
+                   "qcom,pmi8962",
+                   "qcom,pmd9635",
+                   "qcom,pm8994",
+                   "qcom,pmi8994",
+                   "qcom,pm8916",
+                   "qcom,pm8004",
+                   "qcom,pm8909",
+                   "qcom,pm8950",
+                   "qcom,pmi8950",
+                   "qcom,pm8998",
+                   "qcom,pmi8998",
+                   "qcom,pm8005",
+                   or generalized "qcom,spmi-pmic".
+- reg:             Specifies the SPMI USID slave address for this device.
+                   For more information see:
+                   Documentation/devicetree/bindings/spmi/spmi.yaml
+
+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";
+			};
+		};
+	};
