+title: Qualcomm Light Pulse Generator
+
+maintainers:
+ - Bjorn Andersson <bjorn.andersson@linaro.org>
+
+description: >
+ The Qualcomm Light Pulse Generator consists of three different hardware blocks;
+ a ramp generator with lookup table, the light pulse generator and a three
+ channel current sink. These blocks are found in a wide range of Qualcomm PMICs.
