Add check to proceed handling SoundWire interrupts when valid status is reported in any one of the status registers. Signed-off-by: Vijendar Mukunda Link: https://lore.kernel.org/r/20250620102617.73437-2-Vijendar.Mukunda@amd.com Signed-off-by: Vinod Koul

soundwire: amd: fix for clearing command status register

2025-06-26T20:55:18+00:00

To clear the valid result status, 1 should be written to ACP_SDW_IMM_CMD_STS register. Update the ACP_SW_IMM_CMD_STS register value as 1.

soundwire: amd: fix for handling slave alerts after link is down

2025-06-09T16:11:36+00:00

Sometimes, its observed that during system level suspend callback execution, after link is down, handling pending slave status workqueue results in mipi register access failures as shown below. soundwire sdw-master-0-0: trf on Slave 1 failed:-110 read addr 0 count 1 rt722-sdca sdw:0:0:025d:0722:01: SDW_DP0_INT recheck read failed:-110 rt722-sdca sdw:0:0:025d:0722:01: Slave 1 alert handling failed: -110 amd_sdw_manager amd_sdw_manager.0: SDW0 cmd response timeout occurred amd_sdw_manager amd_sdw_manager.0: command timeout for Slave 1 soundwire sdw-master-0-0: trf on Slave 1 failed:-110 write addr 5c count 1 amd_sdw_manager amd_sdw_manager.0: SDW0 previous cmd status clear failed amd_sdw_manager amd_sdw_manager.0: command timeout for Slave 1 soundwire sdw-master-0-0: trf on Slave 1 failed:-110 write addr 5d count 1 amd_sdw_manager amd_sdw_manager.0: SDW0 previous cmd status clear failed amd_sdw_manager amd_sdw_manager.0: command timeout for Slave 1 Cancel the pending slave status workqueue prior to initiating clock stop sequence during suspend callback execution for both the power modes.

soundwire: amd: serialize amd manager resume sequence during pm_prepare

2025-06-09T16:08:28+00:00

During pm_prepare callback, pm_request_resume() delays SoundWire manager D0 entry sequence. Synchronize runtime resume sequence for amd_manager instance prior to invoking child devices resume sequence for both the amd power modes(ClockStop Mode and Power off mode). Change the power_mode_mask check and use pm_runtime_resume() in amd_pm_prepare() callback.

soundwire: amd: add soundwire host wake interrupt enable/disable sequence

2025-02-13T16:21:07+00:00

For wake event, SoundWire host wake interrupt will be asserted based on below pre-conditions for ACP7.0 & ACP7.1 platforms. - ACP device should be in D0 state. - SoundWire manager instance should be in D3 state. - SoundWire manager device state should be set to D3. - ACP_PME_EN should be set to 1. Implement code changes to enable/disable SoundWire host wake interrupt mask during suspend and resume as per design flow for ACP7.0 & ACP7.1 platforms.
