^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) 		This file allows the driver for a device to be specified which
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) 		will override standard OF, ACPI, ID table, and name matching.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 		When specified, only a driver with a name matching the value
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 		written to driver_override will have an opportunity to bind
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 		to the device.  The override is specified by writing a string
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) 		to the driver_override file (echo vfio-platform > \
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) 		driver_override) and may be cleared with an empty string
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 		(echo > driver_override).  This returns the device to standard
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 		matching rules binding.  Writing to driver_override does not
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 		automatically unbind the device from its current driver or make
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 		any attempt to automatically load the specified driver.  If no
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) 		driver with a matching name is currently loaded in the kernel,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) 		the device will not bind to any driver.  This also allows
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) 		devices to opt-out of driver binding using a driver_override
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) 		name such as "none".  Only a single driver may be specified in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) 		the override, there is no support for parsing delimiters.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) 		This file contains the NUMA node to which the platform device
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) 		is attached. It won't be visible if the node is unknown. The
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) 		value comes from an ACPI _PXM method or a similar firmware
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) 		source. Initial users for this file would be devices like
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) 		arm smmu which are populated by arm64 acpi_iort.
