+Qualcomm's LAB(LCD AMOLED Boost)/IBB(Inverting Buck Boost) Regulator
+
+LAB can be used as a positive boost power supply and IBB can be used as a negative
+boost power supply for display panels. Currently implemented for pmi8998.
+
+Main node required properties:
+
+- compatible:			Must be:
+				"qcom,pmi8998-lab-ibb"
+- #address-cells:		Must be 1
+- #size-cells:			Must be 0
+
+LAB subnode required properties:
+
+- interrupts:			Specify the interrupts as per the interrupt
+				encoding.
+- interrupt-names:		Interrupt names to match up 1-to-1 with
+				the interrupts specified in 'interrupts'
+				property.
+
+IBB subnode required properties:
+
+- interrupts:			Specify the interrupts as per the interrupt
+				encoding.
+- interrupt-names:		Interrupt names to match up 1-to-1 with
+				the interrupts specified in 'interrupts'
+				property.
+
+Example:
+	pmi8998_lsid1: pmic@3 {
+		labibb {
+			compatible = "qcom,pmi8998-lab-ibb";
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			lab: lab {
+				interrupts = <0x3 0xde 0x0 IRQ_TYPE_EDGE_RISING>;
+				interrupt-names = "lab-sc-err";
+			};
+
+			ibb: ibb {
+				interrupts = <0x3 0xdc 0x2 IRQ_TYPE_EDGE_RISING>;
+				interrupt-names = "ibb-sc-err";
+			};
+
+		};
+	};
