ASoC: SOF: rename cores_mask to host_managed_cores_mask

2020-09-11T14:29:29Z

Rename the cores_mask in struct sof_intel_dsp_desc to host_managed_cores_mask to be more indicative of the fact that only these cores can be powered up/down by the host.

ASoC: SOF: Intel: Baytrail: fix 'defined but not used' warnings

2020-05-29T15:55:31Z

With the allmodconfig option, CONFIG_SND_SOC_SOF_BAYTRAIL is disabled due to mutual exclusion with the legacy driver. This generates 'defined by not used' warnings. suspend/resume/remove are only supported for Baytrail for now, so move the code under the CONFIG_SND_SOC_SOF_BAYTRAIL checks.

ASoC: SOF: Intel: BYT: harden IPC initialization and handling

2020-05-27T13:06:59Z

On probe and reset, we should not touch the SHIM_IMRD register since it is configured by firmware. The driver only configures SHIM_IMRX with the BUSY interrupt enabled by default and DONE interrupt disabled. When sending an IPC message, the DONE interrupt is enabled until the DSP response is provided. This sequence hardens the IPC communication and avoid interrupt-related issues when adding/removing modules or during system suspend-resume transitions.

ASoC: SOF: Intel: BYT: mask BUSY or DONE interrupts in handler

2020-05-27T13:06:58Z

The DSP may send the same interrupt multiple times before it's handled in the interrupt thread. Rather than masking it in the thread, mask it in the handler directly. This patch also removes useless checks that cannot happen, and masks that are set don't need to be re-tested.

ASoC: SOF: Intel: add min/max channels for SSP on Baytrail/Broadwell

2020-04-17T18:37:15Z

Major regressions were detected by SOF CI on CherryTrail and Broadwell: [ 25.705750] SSP2-Codec: ASoC: no backend playback stream [ 27.923378] SSP2-Codec: ASoC: no users playback at close - state This is root-caused to the introduction of the DAI capability checks with snd_soc_dai_stream_valid(). Its use in soc-pcm.c makes it a requirement for all DAIs to report at least a non-zero min_channels field. For some reason the SSP structures used for SKL+ did provide this information but legacy platforms didn't.
