[PATCH v3 11/20] ASoC: tegra20: spdif: Support system suspend

From: Dmitry Osipenko <digetx@gmail.com>
Date: 2021-12-02 16:27:05
Also in: alsa-devel, dri-devel, linux-tegra, lkml
Subsystem: sound, sound - soc layer / dynamic audio power management (asoc), the rest · Maintainers: Jaroslav Kysela, Takashi Iwai, Liam Girdwood, Mark Brown, Linus Torvalds

Support system suspend by enforcing runtime PM suspend/resume.
Now there is no doubt that h/w is indeed stopped during suspend
and that h/w state will be properly restored after resume.
