title: Amlogic Meson IR transmitter

maintainers:
  - Viktor Prutyanov <viktor.prutyanov@phystech.edu>

description: |
  Some Amlogic SoCs such as A311D and T950D4 have IR transmitter
  (also called blaster) controller onboard. It is capable of
  sending IR signals with arbitrary carrier frequency and duty cycle.
