2019-10-29ASoC: intel - fix the card namesJaroslav Kysela3-3/+3
Those strings are exposed to the user space as the card name thus used in the GUIs. The common standard is to avoid '_' here. The worst case is 'sof-skl_hda_card' string.

2019-10-28ASoC: SOF: PM: Add support for DSP D0i3 state when entering S0ixKeyon Jie1-0/+46
When system is entering into S0ix, the PCI device may transition to the D0i3 substate instead of D3. In D0i3, some always-on functionality can be enabled, such as acoustic event detection, voice activity detection or hotwording. When an event is detected, the DSP firmware can wake-up the device for a transition to D0 with an interrupt.

2019-10-28ASoC: SOF: ignore suspend/resume for D0ix compatible streamsKeyon Jie2-1/+47
During system suspend, the PM framework will freeze all applications and the ALSA/ASoC core will suspend all RUNNING PCM streams. However, D0ix-compatible PCM streams should keep the related pipelines active in the DSP when the system is entering S0ix. The TRIGGER_SUSPEND event is trapped in such cases to prevent the pipelines from being stopped. Likewise, the TRIGGER_RESUME/START events should not affect the pipeline state. The SOF driver also triggers some DSP Firmware pipelines based on the DAPM widgets power events. In such cases, we also ignore PRE_PMU and POST_PMD events to keep the pipelines active.

The devm conversion of kirkwood was incorrect; on removal, devm takes effect after the "remove" function has returned. So, the effect of the conversion was to change the order during remove from: - snd_soc_unregister_component() (unpublishes interfaces) - clk_disable_unprepare() - cleanup resources After the conversion, this became: - clk_disable_unprepare() - while the device may still be active - snd_soc_unregister_component() - cleanup resources Hence, it introduces a bug, where the internal clock for the device may be shut down before the device itself has been shut down. It is known that Marvell SoCs, including Dove, locks up if registers for a peripheral that has its clocks disabled are accessed.
