soundwire: stream: extend sdw_alloc_stream() to take 'type' parameter

2026-01-08T09:15:04+00:00

[ Upstream commit dc90bbefa792031d89fe2af9ad4a6febd6be96a9 ] In the existing definition of sdw_stream_runtime, the 'type' member is never set and defaults to PCM. To prepare for the BPT/BRA support, we need to special-case streams and make use of the 'type'. No functional change for now, the implicit PCM type is now explicit.

soundwire: bus: drop unused driver name field

soundwire: bus: add stream refcount

2024-06-03T12:10:23+00:00

The notion of stream is by construction based on a multi-bus capability, to allow for aggregation of Peripheral devices or functions located on different segments. We currently count how many master_rt contexts are used by a stream, but we don't have the dual refcount of how many streams are allocated on a given bus. This refcount will be useful to check if BTP/BRA streams can be allocated. Note that the stream_refcount is modified in sdw_master_rt_alloc() and sdw_master_rt_free() which are both called with the bus_lock mutex held, so there's no need for refcount_ primitives for additional protection.

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.

soundwire: bus: introduce controller_id

2023-11-24T06:54:37+00:00

The existing SoundWire support misses a clear Controller/Manager hiearchical definition to deal with all variants across SOC vendors. a) Intel platforms have one controller with 4 or more Managers. b) AMD platforms have two controllers with one Manager each, but due to BIOS issues use two different link_id values within the scope of a single controller. c) QCOM platforms have one or more controller with one Manager each. This patch adds a 'controller_id' which can be set by higher levels. If assigned to -1, the controller_id will be set to the system-unique IDA-assigned bus->id. The main change is that the bus->id is no longer used for any device name, which makes the definition completely predictable and not dependent on any enumeration order. The bus->id is only used to insert the Managers in the stream rt context.

Add cs42l43 PC focused SoundWire CODEC

Merge series from Charles Keepax : This patch chain adds support for the Cirrus Logic cs42l43 PC focused SoundWire CODEC. The chain is currently based of Lee's for-mfd-next branch. This series is mostly just a resend keeping pace with the kernel under it, except for a minor fixup in the ASoC stuff.
