ASoc: simple-mux: Allow to specify an idle-state

2024-11-14T15:36:46Z

Merge series from "Hendrik v. Raven" : This series adds support for the idle-state property from the mux framework to the simple-mux audio variant. It allows to specify the state of the mux when it is not in use.

soundwire: Update the includes on the sdw.h header

2024-11-14T06:41:17Z

There are quite a few things used in the sdw.h header that it relies on the consumer to include. If something is used directly in the header it should be included by the header. Update the includes to cover the missing items, or add forward declarations for things that are only used as pointers. Whilst making the change also alphabetise the list of includes.

ASoC: SDCA: add initial module

2024-10-17T17:42:11Z

Add new module for SDCA (SoundWire Device Class for Audio) support. For now just add a parser to identify the SDCA revision and the function mask. Note that the SDCA definitions and related MIPI DisCo properties are defined only for ACPI platforms and extracted with _DSD helpers. There is currently no support for Device Tree in the specification, the 'depends on ACPI' reflects this design limitation. This might change in a future revision of the specification but for SDCA 1.0 ACPI is the only supported type of platform firmware. The SDCA library is defined with static inline fallbacks, which will allow for unconditional addition of SDCA support in common parts of the code. The design follows a four-step process: 1) Basic information related to Functions is extracted from MIPI DisCo tables and stored in the 'struct sdw_slave'. Devm_ based memory allocation is not allowed at this point prior to a driver probe, so we only store the function node, address and type. 2) When a codec driver probes, it will register subdevices for each Function identified in phase 1) 3) a driver will probe for each subdevice and addition parsing/memory allocation takes place at this level. devm_ based allocation is highly encouraged to make error handling manageable. 4) Before the peripheral device becomes physically attached, register access is not permitted and the regmaps are cache-only. When peripheral device is enumerated, the bus level uses the 'update_status' notification; after optional device-level initialization, the codec driver will notify each of the subdevices so that they can start interacting with the hardware. Note that the context extracted in 1) should be arguably be handled completely in the codec driver probe. That would however make it difficult to use the ACPI information for machine quirks, and e.g. select different machine driver and topologies as done for the RT712_VB handling later in the series. To make the implementation of quirks simpler, this patchset extracts a minimal amount of context (interface revision and number/type of Functions) before the codec driver probe, and stores this context in the scope of the 'struct sdw_slave'. The SDCA library can also be used in a vendor-specific driver without creating subdevices, e.g. to retrieve the 'initialization-table' values to write platform-specific values as needed.

ASoC/soundwire: remove sdw_slave_extended_id

2024-10-17T17:42:10Z

This structure is used to copy information from the 'sdw_slave' structures, it's better to create a flexible array of 'sdw_slave' pointers and directly access the information. This will also help access additional information stored in the 'sdw_slave' structure, such as an SDCA context. This patch does not add new functionality, it only modified how the information is retrieved.

soundwire: mipi-disco: add support for DP0/DPn 'lane-list' property

2024-10-03T07:58:51Z

The SoundWire specification did not clearly require that ports could use all Lanes. Some SoundWire/SDCA peripheral adopters added restrictions on which lanes can be used by what port, and the DisCo for SoundWire 2.1 specification added a 'lane-list' property to model this hardware limitation. When not specified, the ports can use all Lanes. Otherwise, the 'lane-list' indicates which Lanes can be used, sorted by order of preference (most-preferred-first). This patch only reads the properties, the use of this property will come at a later time with multi-lane support.

soundwire: mipi-disco: add new properties from 2.0 spec

2024-10-03T07:58:51Z

The DisCo for SoundWire 2.0 spec adds support for new 'mipi-sdw-sdca-interrupt-register-list' and 'mipi-sdw-commit-register-supported'. This patch only adds the definitions and property reads, but the use of these properties will come at some point in the future when needed. Note a slight conceptual disconnect between the MIPI DisCo definition of a boolean property and the Linux implementation. The latter only checks the presence of the property to set its value to 'true', whereas the MIPI definitions allow for a property with a 'false' value. This patch uses the new introduced mipi_device_property_read_bool() to handle it.
