+What: /sys/bus/platform/devices/.../driver_override
+Date: April 2014
+Contact: Kim Phillips <kim.phillips@freescale.com>
+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-platform > \
+ 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.
