ASoC: SDCA: Factor out jack handling into new c file

2025-12-22T09:00:56+00:00

The jack code is perhaps a bit large for being in the interrupt code directly. Improve the encapsulation by factoring out the jack handling code into a new c file, as is already done for HID and FDL. Whilst doing so also add a jack_state structure to hold the jack state for improved expandability in the future.

ASoC: SDCA: Add basic SDCA function driver

2025-11-20T17:23:01+00:00

Add a driver to support the individual SDCA functions within the class driver. Use the SDCA helpers to parse the DisCo information and register a function driver based on those properties. Manage the boot of the function, reset, FDL, defaults. Manage the function level register map.

ASoC: SDCA: Add basic SDCA class driver

2025-11-20T17:23:00+00:00

Add a device level driver as the entry point for the class driver. Additional auxiliary drivers will be registered to support each function within the device. This driver will register those function drivers and provide the device level functionality, such as monitoring bus attach/detach, the device level register map, and the root for the IRQ handling.

ASoC: SDCA: add function devices

2025-11-20T17:22:59+00:00

Use the auxiliary bus to register/unregister subdevices for each function. Each function will be handled with a separate driver, matched using a name. If a vendor wants to override a specific function driver, they could use a custom name to match with a custom function driver.

ASoC: SDCA: Add FDL library for XU entities

2025-10-27T15:31:24+00:00

Some instances of the XU Entity have a need for Files to be downloaded from the Host. In these XUs, there is one instance of a Host to Device (Consumer) UMP, identified by the FDL_CurrentOwner Control. FDL Library introduced here implements the FDL flow triggered by FDL_CurrentOwner irq, which sends a file from SoundWire File Table (SWFT) or from the firmware directory in specific cases, to the Device FDL UMP. Currently only Direct method of FDL is implemented.

ASoC: SDCA: Add UMP buffer helper functions

2025-10-27T15:31:22+00:00

Add helper functions for handling Universal Message Passing (UMP) buffers on SDCA devices. These are generic mechanisms to pass blocks of binary data between the host and the device, in both directions. They are used for things like passing HID descriptors and the File Download process.

ASoC: SDCA: Pull HID and IRQ into the primary SDCA module

2025-07-13T21:36:40+00:00

If the HID or the IRQ are selected as options they will always require loading alongside the main SDCA module. Since it will never be possible to run without them the value of keeping them as separate modules is fairly limited. Pull them into the main SDCA module to simplify things still further.

Tidy up a few bits of the SDCA Kconfig. Default both HID and IRQ to enabled, since typically if one wants SDCA all the functionality will be expected. Finally, update the IRQ support to match the changes made to the HID support.

ASoC: SDCA: fix HID dependency

2025-07-09T15:42:22+00:00

It is not possible to enable SND_SOC_SDCA_HID when SND_SOC_SDCA is built-in but HID is in a loadable module, as that results in a link failure: x86_64-linux-ld: sound/soc/sdca/sdca_functions.o: in function `find_sdca_entity_hide': sdca_functions.c:(.text+0x25b): undefined reference to `sdca_add_hid_device' Change SND_SOC_SDCA_HID into a 'bool' option that can only be enabled if this results in a working build, and change the Makefile so this driver is a loadable module if possible.

ASoC: SDCA: Generic interrupt support

2025-06-30T15:04:17+00:00

Add a library supporting usage of SDCA interrupts, using regmap irq framework. The library adds functions for parsing ACPI for interrupt-related information, configuring irq chip and requesting individual irqs. Calling code (SDCA function code) is expected to also substitute the library's base irq handler for its own, appropriate callback.
