[PATCH 02/16] ASoC: SOF: amd: add base platform support for ACP7.B/7.F
From: Vijendar Mukunda
Date: Wed Jul 01 2026 - 05:59:07 EST
Add SOF support for ACP7.B and ACP7.F PCI revision based platforms.
This covers Kconfig/Makefile entries, register offset definitions,
DMA descriptor/channel/status paths, PGFSM power-on handling,
PCI device driver, I2S/DMIC DAI definitions, and IPC SW interrupt
trigger offset selection for ACP7.B/7.F.
