1What: /sys/bus/amba/devices/.../driver_override2Date: September 20143Contact: Antonios Motakis <a.motakis@virtualopensystems.com>4Description:5 This file allows the driver for a device to be specified which6 will override standard OF, ACPI, ID table, and name matching.7 When specified, only a driver with a name matching the value8 written to driver_override will have an opportunity to bind to9 the device. The override is specified by writing a string to the10 driver_override file (echo vfio-amba > driver_override) and may11 be cleared with an empty string (echo > driver_override).12 This returns the device to standard matching rules binding.13 Writing to driver_override does not automatically unbind the14 device from its current driver or make any attempt to15 automatically load the specified driver. If no driver with a16 matching name is currently loaded in the kernel, the device will17 not bind to any driver. This also allows devices to opt-out of18 driver binding using a driver_override name such as "none".19 Only a single driver may be specified in the override, there is20 no support for parsing delimiters.21
