2024-10-17soundwire: intel_ace2x: Send PDI stream number during prepareRanjani Sridharan
In the case of a prepare callback after an xrun or when the PCM is restarted after a call to snd_pcm_drain/snd_pcm_drop, avoid reprogramming the SHIM registers but send the PDI stream number so that the link DMA data can be set. This is needed for the case that the DMA data is cleared when the PCM is stopped and restarted without being closed.

In older platforms, the number of links was constant and hard-coded to 4. Newer platforms can have varying number of links, so we need to add a probe-time check to make sure the ACPI-reported information with _DSD properties is aligned with hardware capabilities reported in the SoundWire LCAP register.

2024-04-26soundwire: intel_ace2x: simplify check_wake()Pierre-Louis Bossart
Since LunarLake, we use the HDadio WAKEEN/WAKESTS to detect wakes for SoundWire codecs. This patch follows the HDaudio example and simplifies the behavior on wake-up by unconditionally waking up all links. This behavior makes a lot of sense when removing the jack, which may signal that the user wants to start rendering audio using the local amplifiers. Resuming all links helps make sure the amplifiers are ready to be used. Worst case, the pm_runtime suspend would kick-in after several seconds of inactivity.

2024-04-26soundwire: intel_ace2x: fix wakeup handlingPierre-Louis Bossart
The initial programming sequence only worked in the case where the OFLEN bit is set, i.e. the DSP handles the SoundWire interface. In the Linux integration, the interface is owned by the host. This disconnect leads to wake-ups being routed to the DSP and not to the host. The suggested update is to rely on the global HDAudio WAKEEN/STATESTS registers, with the SDI bits used to program the wakeups and check the status. Note that there is no way to know which peripheral generated a wake-up. When the hardware detects a change, it sets all the bits corresponding to LSDIIDx. The LSDIIDx information can be used to figure out on which link the wakeup happened, but for further details the software will have to check the status of each peripheral.

2023-11-28soundwire: intel_ace2x: fix AC timing setting for ACE2.xChao Song
Start from ACE1.x, DOAISE is added to AC timing control register bit 5, it combines with DOAIS to get effective timing, and has the default value 1. The current code fills DOAIS, DACTQE and DODS bits to a variable initialized to zero, and updates the variable to AC timing control register. With this operation, We change DOAISE to 0, and force a much more aggressive timing. The timing is even unable to form a working waveform on SDA pin. This patch uses read-modify-write operation for the AC timing control register access, thus makes sure those bits not supposed and intended to change are not touched.
