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.
