From ce84a347bfa16f393e75e4cc63eded636ca69af8 Mon Sep 17 00:00:00 2001 From: CoolStar Date: Sun, 15 Oct 2023 16:51:54 -0700 Subject: acpi: Reserve hardware ID for custom AMD ACP driver AMD Audio CoProcessor handles I2S audio on AMD SoC's. Prior to AMD Ryzen platforms (e.g. STONEY) it is located on the Integrated GFX device. As the proprietary AMD driver does not support accessing this easily, reserve a custom ACPI ID from the coreboot namespace so that another driver can be attached in Windows device manager.
