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.

soundwire: amd: fix for wake interrupt handling for clockstop mode

2024-03-28T18:10:33+00:00

When SoundWire Wake interrupt is enabled along with SoundWire Wake enable register, SoundWire wake interrupt will be reported when SoundWire manager is in D3 state and ACP is in D3 state. When SoundWire Wake interrupt is reported, it will invoke runtime resume of the SoundWire manager device. In case of system level suspend, for ClockStop Mode SoundWire Wake interrupt should be disabled. It should be enabled only for runtime suspend scenario. Change wake interrupt enable/disable sequence for ClockStop Mode in system level suspend and runtime suspend sceanrio.

soundwire: amd: refactor register mask structure

2024-01-30T16:06:36+00:00

Register mask array structure is no longer needed as except interrupt control masks, rest of the register masks are not used in code. Use array for interrupt masks instead of structure.
