ASoC: SOF: Intel: pci-tgl: unblock S5 entry if DMA stop has failed"

2022-12-12T15:44:20Z

If system shutdown has not been completed cleanly, it is possible the DMA stream shutdown has not been done, or was not clean. If this is the case, Intel TGL/ADL HDA platforms may fail to shutdown cleanly due to pending HDA DMA transactions. To avoid this, detect this scenario in the shutdown callback, and perform an additional controller reset. This has been tested to unblock S5 entry if this condition is hit.

ASoC: SOF: Intel: hda: add callback to check SoundWire lcount information

2022-11-23T15:32:05Z

The number of links is stored in different registers depending on the IP version, add sdw_check_lcount() callback. This callback only checks that the number of links supported in hardware is compatible with the number of links exposed in ACPI _DSD properties.

ASoC: SOF: Intel: hda: add per-chip enable_sdw_irq() callback

2022-11-23T15:32:02Z

Different generations of Intel hardware rely on different programming sequences to enable SoundWire IP. In existing hardware, the SoundWire interrupt is enabled with a register field in the DSP register space. With HDaudio multi-link extensions registers, the SoundWire interrupt will be enabled with a generic interrupt enable field in LCTL, without any dependency on the DSP being enabled. Add a per-chip callback following the example of the check_sdw_irq() model already upstream. Note that the callback is not populated yet for MeteorLake (MTL) since the interrupts are already enabled in the init. A follow-up patch will move the functionality to this callback after a couple of cleanups.
