soundwire: amd: serialize amd manager resume sequence during pm_prepare

2025-08-20T16:30:45+00:00

[ Upstream commit 03837341790039d6f1cbf7a1ae7dfa2cb77ef0a4 ] 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.

[ Upstream commit a628e69b6412dc02757a6a23f7f16ce0c14d71f1 ] 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.

[ Upstream commit dcc48a73eae7f791b1a6856ea1bcc4079282c88d ] During runtime suspend scenario, SoundWire wake should be enabled and during system level suspend scenario SoundWire wake should be disabled. Implement the SoundWire wake enable/disable sequence as per design flow for SoundWire poweroff mode.
