soundwire: intel: add probe-time check on link id

2024-08-19T11:25:52+00:00

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.

soundwire: cadence: re-check Peripheral status with delayed_work

2024-08-18T06:44:24+00:00

The SoundWire peripheral enumeration is entirely based on interrupts, more specifically sticky bits tracking state changes. This patch adds a defensive programming check on the actual status reported in PING frames. If for some reason an interrupt was lost or delayed, the delayed work would detect a peripheral change of status after the bus starts. The 100ms defined for the delay is not completely arbitrary, if a Peripheral didn't join the bus within that delay then probably the hardware link is broken, and conversely if the detection didn't happen because of software issues the 100ms is still acceptable in terms of user experience. The overhead of the one-shot workqueue is minimal, and the mutual exclusion ensures that the interrupt and delayed work cannot update the status concurrently.

soundwire: intel_ace2.x: add AC timing extensions for PantherLake

2024-06-03T12:11:11+00:00

The ACE3 IP used in PantherLake exposes new bitfields in the ACTMCTL register to better control clocks/delays. These bitfields were reserved/zero in the ACE2.x IP, to simplify the integration the new bifields are added unconditionally. The behavior will only be impacted when the firmware exposes DSD properties to set non-zero values.

soundwire: intel_ace2x: use DOAIS and DODS settings from firmware

2024-05-04T12:56:50+00:00

Starting with LNL, the recommendation is to use settings read from DSD properties instead of hard-coding the values. The DOAIS and DODS values are completely-specific to Intel and are stored in a vendor-specific property structure.
