+Description:
+ This file allows the driver for a device to be specified which
+ will override standard OF, ACPI, ID table, and name matching.
+ When specified, only a driver with a name matching the value
+ written to driver_override will have an opportunity to bind to
+ the device. The override is specified by writing a string to the
+ driver_override file (echo vfio-amba > driver_override) and may
+ be cleared with an empty string (echo > driver_override).
+ This returns the device to standard matching rules binding.
+ Writing to driver_override does not automatically unbind the
+ device from its current driver or make any attempt to
+ automatically load the specified driver. If no driver with a
+ matching name is currently loaded in the kernel, the device will
+ not bind to any driver. This also allows devices to opt-out of
+ driver binding using a driver_override name such as "none".
+ Only a single driver may be specified in the override, there is
+ no support for parsing delimiters.
