+title: Qualcomm's LAB(LCD AMOLED Boost)/IBB(Inverting Buck Boost) Regulator
+
+maintainers:
+  - Sumit Semwal <sumit.semwal@linaro.org>
+
+description:
+  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.
