-          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";
-			};
-		};
-	};
