ASoC machine driver acquires DAPM endpoints through reading "ignore-suspend-widgets" property from DT and then forces the path between these endpoints ignoring suspend. If the rpmsg sound card is in low power audio mode, the suspend/resume callback of binding codec is overridden to disable the suspend/resume.
