[V3,0/9] ASoC: amd: ps: add SoundWire support

Message

Vijendar Mukunda June 6, 2023, 6:07 a.m. UTC

This patch series add support for
	- Platform device creation for SoundWire Manager instances and
	  PDM controller.
	- SoundWire DMA driver.
	- Interrupt handling for SoundWire manager related interrupts,
	  SoundWire DMA interrupts and ACP error interrupts.
	- ACP PCI driver PM ops modification with respect to SoundWire
	  Power modes.

Changes since v1:
	- update "soundwire" as "SoundWire" in code.
	- add comments for platform device mask and platform device
	  count
	- remove unused variables in acp pci driver private data
	  structure
	- refactor dma enable register structures in SoundWire DMA driver
	- add TODO comments in IRQ handler
	- update IRQ mask values using bit macros
	- Fix build error reported in Makefile
	- rename "sdw_dma_stream_instance" structure name as "acp_sdw_dma_stream"

changes since v2:
	- add comments in irq handler.
	- remove workqueue for SoundWire DMA interrupts and use thread
	  implementation for DMA interrupt handling.
	- add error checks in sdw_amd_scan_controller()
	- remove passing "acp_lock" as platform resource for SoundWire DMA driver
	  and PDM driver.
	- retrieve "acp_lock" reference from parent driver directly and
	  use the reference in SoundWire DMA driver.
	- add handling for acp pci driver probe even when no ACP PDM or
	  SoundWire manager platform devices created.
	- Fix indentation for acp_sdw_dma_count structure variables.
	- Use macro instead of hard coded values for FIFO offset and PTE offset.
	- Change pm_runtime enable sequence in SoundWire DMA driver
	  probe function.
	- Refactor system level resume callback in SoundWire DMA
	  driver.
