From 7a5cb145a9ce844be41ca5ed26e7d8d7c41dec7d Mon Sep 17 00:00:00 2001 From: Igor Korotin Date: Fri, 20 Jun 2025 16:39:13 +0100 Subject: rust: driver: Add ACPI id table support to Adapter trait Extend the `Adapter` trait to support ACPI device identification. This mirrors the existing Open Firmware (OF) support (`of_id_table`) and enables Rust drivers to match and retrieve ACPI-specific device data when `CONFIG_ACPI` is enabled. To avoid breaking compilation, a stub implementation of `acpi_id_table()` is added to the Platform adapter; the full implementation will be provided in a subsequent patch.
