ASoC: SDCA: Add stubs for FDL helper functions

2025-11-20T17:22:32+00:00

In the case the SDCA IRQ is built in but FDL support is not stub functions are required for the FDL helpers to avoid build failures. The FDL IRQs likely shouldn't get triggered in this case, however they would still be a part of the build.

ASoC: SDCA: Add UMP timeout handling for FDL

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

Several of the UMP transactions in the FDL process should timeout if the device does not respond within a certain time, add handling into the UMP helpers and the FDL code to handle this.

ASoC: SDCA: Add completion for FDL start and stop

2025-10-27T15:31:26+00:00

Add some completions and a helper function to allow other parts of the system to wait for FDL to complete. The sdca_fdl_sync() function will wait until it completes a full time out without a new FDL request happening, this ensures that even parts requiring multiple rounds of FDL should be fully downloaded before the driver boot continues.

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.
