2024-05-06ASoC: Intel: catpt: clarify Copyright informationPierre-Louis Bossart
For some reason a number of files included the "All rights reserved" statement. Good old copy-paste made sure this mistake proliferated. Remove the "All rights reserved" in all Intel-copyright to align with internal guidance.

2020-10-02ASoC: Intel: catpt: PCM operationsCezary Rojewski
DSP designed for Lynxpoint and Wildcat Point offers no dynamic topology i.e. all pipelines are already defined within firmware and host is relegated to allocing stream for predefined pins. This is represented by 'catpt_topology' member. Implementation covers all available pin types: - system playback and capture - two offload streams - loopback (reference) - bluetooth playback and capture PCM DAI operations differentiate between those pins as some (mainly offload) are to be handled differently - DSP expects wp updates on each notify_position notification. System playback has no volume control capability as it is routed to mixer stream directly. Other primary streams - capture and two offloads - offer individual volume controls. Compared to sound/soc/intel/haswell this configures SSP device format automatically on pcm creation.

2020-10-02ASoC: Intel: catpt: Implement IPC protocolCezary Rojewski
Implement IRQ handlers for immediate and delayed replies and notifications. Communication is synchronous and allows for serialization of maximum one message at a time. DSP may respond with ADSP_PENDING status for a request - known as delayed reply - and when situation occurs, framework keeps the lock and awaits upcoming response through IPCD channel which is handled in bottom-half. Immediate replies spawn no BH at all as their processing is very short.
