Linux 6.17 SoundWire Support Extended To Upcoming AMD ACP 7.2 Hardware

([Hardware] 6 Hours Ago AMD Audio Co-Processor 7.2`)


The Linux 6.17 sound subsystem code last week [1]introduced support for AMD ACP 7.2 as the next version of AMD's Audio Co-Processor IP. This appears to be for yet-to-be-released hardware and now over in the SoundWire subsystem is similar enablement work landing for AMD ACP 7.2.

Last week in the sound subsystem AMD ACP 7.2 support was enabled for DMIC and I2S and associated bits. This week the AMD ACP 7.2 support coverage was merged for SoundWire, the MIPI standard for small audio peripherals.

SoundWire for AMD ACP 7.2 platforms is following the same driver code paths as ACP 7.1 and ACP 7.0. ACP 7.0 aligns with the AMD Ryzen AI 300 series SoCs.

"soundwire updates for 6.17

Couple of small core changes and driver updates:

- Core: handling of nesting irqs to outside the lock, stream parameters handing on port prep failures.

- AMD driver support for ACP 7.2 platforms and improved handing of slave alerts and resume sequences

- Qualcomm updating driver debug spew

- Intel BPT message length limitations, rt721 codec as wake capable etc"

The patches don't confirm what planned AMD products will feature AMD ACP 7.2 but presumably some of their next-generation hardware. More details on all of the SoundWire changes for Linux 6.17 via [2]this pull .
