2024-05-06ASoC: Intel: avs: 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.

2024-04-19ASoC: Intel: avs: Remove unused IRQ-related codeCezary Rojewski
Most IRQ-related code is duplicated in the driver. Switch to the new implementation and remove unused members. While the change is non-trivial, from functional perspective status quo is achieved.

2024-04-19ASoC: Intel: avs: New IRQ handling implementationCezary Rojewski
The existing code can be both improved and simplified. To make this change easier to manage, first add new implementation and then remove deadcode in a separate patch. Simplification achieved with: - reduce the amount of resources requested by the driver i.e.: IPC and CLDMA request_irq() merged into one - reduce the number of DSP ops from 2 to 1: irq_handler/thread() vs dsp_interrupt() - drop ambiguity around CLDMA interrupt, let skl.c handle that explicitly as it is the only user Signed-off-by: Cezary Rojewski <cezary.rojewski@intel.com> Link: https://lore.kernel.org/r/20240419084857.2719593-2-cezary.rojewski@intel.com Signed-off-by: Mark Brown <broonie@kernel.org>
2024-04-05ASoC: Intel: avs: Fix potential integer overflowCezary Rojewski
While stream_tag for CLDMA on SKL-based platforms is always 1, function hda_cldma_setup() uses AZX_SD_CTL_STRM() macro which does: stream_tag << 20 what combined with stream_tag type of 'unsigned int' generates a potential overflow issue. Update the field type to fix that.

Improve readability of CLDMA reset operation by making use of already defined SD_CTL_STREAM_RESET. Signed-off-by: Cezary Rojewski <cezary.rojewski@intel.com> Link: https://lore.kernel.org/r/20220707124153.1858249-11-cezary.rojewski@intel.com Signed-off-by: Mark Brown <broonie@kernel.org>
2022-03-11ASoC: Intel: avs: Implement CLDMA transferCezary Rojewski
SKL and KBL rely on a dedicated HDAudio DMA stream for code loading and authentication. The implementation of this specific mechanism for SKL-based platforms re-uses HDAudio DMA (streaming) functions found in HDA library to avoid duplication of functionality.
