-Subject: [PATCH 240/454] audioinjector-octo: Add continuous clock feature
-
-By user request, add a switch to prevent the clocks being stopped when
-the stream is paused, stopped or shutdown. Provide access to the switch
-by adding a 'non-stop-clocks' parameter to the audioinjector-addons
-overlay.

-See: https://github.com/raspberrypi/linux/issues/2409
