With the chip shortage, some GeminiLake Intel-based designs were respun and now rely on codecs that need the SSP bit clock turned on in the hw_params stage, not the trigger stage. This patchset mirrors the flags added in the SOF DAI_CONFIG IPC, and sets the flags when this capability is indicated as necessary in the topology files where the SSP configuration is stored.
We initially considered a more generic solution with an on-demand SSP clock activation using the common clock framework. This would be a more elegant solution indeed, but it would have required more intrusive changes that would conflict with the SOF multi-client support (in-development), and more backport hassles on product branches. The on-demand activation of clocks is still a desired feature that will be enabled at a later point.
