0004 Description:
0005 This file allows the driver for a device to be specified which
0006 will override standard OF, ACPI, ID table, and name matching.
0007 When specified, only a driver with a name matching the value
0008 written to driver_override will have an opportunity to bind to
0009 the device. The override is specified by writing a string to the
0010 driver_override file (echo vfio-amba > driver_override) and may
0011 be cleared with an empty string (echo > driver_override).
0012 This returns the device to standard matching rules binding.
0013 Writing to driver_override does not automatically unbind the
0014 device from its current driver or make any attempt to
0015 automatically load the specified driver. If no driver with a
0016 matching name is currently loaded in the kernel, the device will
0017 not bind to any driver. This also allows devices to opt-out of
0018 driver binding using a driver_override name such as "none".
0019 Only a single driver may be specified in the override, there is
0020 no support for parsing delimiters.
