+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";
+ };
+
+ };
+ };
