- 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.
