What: /sys/bus/amba/devices/.../driver_override
Date: September 2014
Contact: Antonios Motakis <a.motakis@virtualopensystems.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-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.

The timeouts are expressed in seconds, minutes, hours and

respectively.
To configure the timeout, write to this file a value along
with any the above units. If no unit is specified, the value
is assumed to be expressed in seconds.
For example, to set the timeout to 10 minutes run:
echo 10m > /sys/class/leds/dell::kbd_backlight/stop_timeout
Note that when this file is read, the returned value might be
expressed in a different unit than the one used when the timeout
was set.
Also note that only some timeouts are supported and that
some systems might fall back to a specific timeout in case
an invalid timeout is written to this file.
