Acpi Prp0001 0 !link! 〈OFFICIAL – TIPS〉

In other words:

A significant issue arose when a driver had both an acpi_match_table and an of_match_table . In such a scenario, acpi_device_get_match_data() would look at the driver's ACPI table, find no entry for PRP0001 , and return NULL, even though the device was successfully matched via the DT table. A 2019 patch from Intel's Andy Shevchenko was among the first to respect PRP0001 in this path. Later, in 2026, this was further refined by a patch that explicitly checks for PRP0001 and fetches the correct match data from the driver's of_match_table .

An ACPI entry for an I2C accelerometer:

So acpi prp0001 0 means:

: The PRP0001 identifier is widely used to enable Industrial I/O (IIO) sensors, which are common in embedded systems. A patch to the mcp4725 DAC driver explicitly notes that it "enables use of ACPI PRP0001". This demonstrates how ACPI systems can leverage IIO drivers originally designed for the Device Tree.

: Windows Device Manager does not always natively parse these _DSD blocks. When Windows encounters ACPI\PRP0001\0 , it sees a device that exists but lacks a structured Windows Plug-and-Play (PnP) driver.

The UUID daffd814-6eba-4d8c-8a91-bc9bbf4aa301 is the standard GUID for hierarchical data extensions in _DSD . This ASL snippet provides the necessary information for the kernel to match the device to the ti,tmp75 driver.
