The kernel uses the of_match_table (Open Firmware match table) of drivers. If you have an I2C device on an ACPI bus, you can define it like this in ACPI: Is it an error
If you are seeing errors or logs regarding PRP0001 in your dmesg output, here is what you need to know. Is it an error?
PRP0001 is conceptually an . By disabling it, you are telling the kernel: "Do not apply any DT overlays found in ACPI tables."
bridges these two. If an ACPI device has PRP0001 as a _HID or _CID , the kernel checks the _DSD object for a compatible property. 2. Why PRP0001 Exists: The Problem it Solves
