At the start of dsp_work() only wait for init_completion if !init_done. This allows system suspend to re-queue dsp_work() without having to do a dummy complete() of init_completion. A dummy completion in system suspend would have to be conditional on init_done. But that would create a possible race condition between our system resume and cs35l56_init() in the corner case that we suspend right after the SoundWire core has enumerated and reported ATTACHED. It is safer and simpler to have cs35l56_init() as the only place that init_completion is completed, and dsp_work() as the only place that it is consumed. Signed-off-by:

If we use a DAPM widget instead of mute_stream() to send the PLAY command we can issue the plays to multiple amps in parallel. With mute_stream each codec driver instance is called one at a time so we get N * PS0 delay time. DAPM does each stage on every widget in a card before moving to the next stage. So all amps will do the PRE_PMU then all will do the POST_PMU. The PLAY is sent in the PRE_PMU so that they all power-up in parallel. After the PS0 wait in the first POST_PMU all the other amps will also be ready so there won't be any extra delay, or it will be negligible. There's also no point waiting for the MBOX ack in the PRE_PMU. We won't see a PS0 state in POST_PMU if it didn't ack the PLAY command. So we can save a little extra time. Signed-off-by:

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: The following series adds the core support to handle the recently updated HDaudio multi-link support to hanlde non HDA links, like SoundWire/DMIC/SSP on Intel platform. For details, please see the first patch which documents the current mlink support (introduced at Skylake) and the new extensions, arriving with LNL. There is no change in functionality for existing HDA support, the extension is backwards compatible with existing implementations.

Each SoundWire peripheral can be programmed from the manager side either with a regular command FIFO, or with the HDaudio CORB/RIRB DMA-based mechanism. The mapping between SoundWire peripheral and SDI address is handled with the LSDIID register. This mapping only works of course if each peripheral has a unique address across all links. This has already been enforced in previous Intel contributions allowing for an IDA-based solution for the device number allocation. The checks on the dev_num are handled at the SoundWire level, but the locking is handled at the hda-mlink level. Signed-off-by:

This helper is an optimization where sync_go is only called when the cmdsync field is actually set to a non-zero value. Since this is also only used by SoundWire for now, only expose the _unlocked version. Signed-off-by:

The multi-link synchronization uses the same concept and registers, but moved to the HDAudio extended links. Add helpers for sync_arm and sync_go which are the basic for the bus reset, bank switch and clock stop. Since SoundWire is the only user of those helpers, only expose the _unlocked versions for now. Note that SYNCGO is a write-only bit, so no error can be reported. We still return 0 for compatibility with the SoundWire stream management headers. Signed-off-by:

These helpers configure the ratio between the base clock and the hardware signal used for link synchronization. The SYNCPRD is written before the first sublink is powered-up. The SYNCPU bit is set, but it will only be cleared after the link is powered-up, hence the implementation with a set/wait pattern. These helpers are currently only needed by SoundWire support, where the lock is taken at a higher level, so only the _unlocked versions are exposed for now. Note that the _wait_bit() implementation is similar to previous helpers in drivers/soundwire, but with sleep duration and timeout aligned with hardware recommendations. If desired, this helper could be modified in a second step with e.g. readl_poll_timeout(). Signed-off-by:

The updated SoundWire Intel driver will need to rely on Extended HDaudio links for power management, but it doesn't need to be aware of all the HDaudio structures. Add convenience helpers to avoid polluting SoundWire drivers too much with HDaudio information. Since the SoundWire/Intel solution already takes the lock at a higher level, the _unlocked PM helpers are used. Signed-off-by:

Pierre-Louis Bossart authored
Add helpers to program SPA/CPA bits, using a mutex to access the shared LCTL register if required. All links are managed with the same LCTLx.SPA bits. However there are quite a few implementation details to be aware of: Legacy HDaudio multi-links are powered-up when exiting reset, which requires the ref_count to be manually set to one when initializing the link. Alternate links for SoundWire/DMIC/SSP need to be explicitly powered-up before accessing the SHIM/IP/Vendor-Specific SHIM space for each sublink. DMIC/SSP/SoundWire are all different cases with a different device/dai/hlink relationship. SoundWire will handle power management with the auxiliary device resume/suspend routine. The ref_count is not necessary in this case. The DMIC/SSP will by contrast handle the power management from DAI .startup and .shutdown callbacks. The SSP has a 1:1 mapping between sublink and DAI, but it's bidirectional so the ref_count will help avoid turning off the sublink when one of the two directions is still in use. The DMIC has a single link but two DAIs for data generated at different sampling frequencies, again the ref_count will make sure the two DAIs can be used concurrently. And last the SoundWire Intel require power-up/down and bank switch to be handled with a lock already taken, so the 'eml_lock' is made optional with the _unlocked versions of the helpers. Note that the _check_power_active() implementation is similar to previous helpers in sound/hda/ext, with sleep duration and timeout aligned with hardware recommendations. If desired, this helper could be modified in a second step with .e.g. readl_poll_timeout() Signed-off-by:

For backwards compatibility, HDaudio/iDISP links are powered-on when exiting reset, and the existing driver forces them to be powered-off when entering S0ix. In addition, the get/put helpers are invoked directly by the ASoC codec drivers, which a historical layering violation. Extended links are powered-on by software only, during the probe and DAI startup phases. This calls for a different handling of the 'regular' and 'extended' audio links. Signed-off-by:

Extend hdac_ext_link to store information needed for ALT links. Follow-up patches will include more functional patches for power-up and down. Note that this patch suggests the use of an 'eml_lock' to serialize access to shared registers. SoundWire-specific sequence require the lock to be taken at a higher level, as a result the helpers added in follow-up patches will provide 'unlocked' versions when needed. Also note that the low-level sequences with the 'hdaml_' prefix are taken directly from the hardware specifications - naming conventions included. The code will be split in two, with locking and linked-list management handled separately to avoid mixing required hardware setup and Linux-based resource management. Signed-off-by:
