amba_device_register - register an AMBA device : AMBA device to register : parent memory resource

Setup the AMBA device, reading the cell ID if present. Claim the resource, and register the AMBA device with the Linux device manager.

Definition at line 641 of file bus.c.

void amba_device_unregister ( struct amba_device * dev )

amba_device_unregister - unregister an AMBA device : AMBA device to remove

Remove the specified AMBA device from the Linux device manager. All files associated with this object will be destroyed, and device drivers notified that the device has been removed. The AMBA device's resources including the amba_device structure will be freed once all references to it have been dropped.

Definition at line 673 of file bus.c.

int amba_driver_register ( struct amba_driver * drv )

amba_driver_register - register an AMBA device driver : amba device driver structure

Register an AMBA device driver with the Linux device model core. If devices pre-exist, the drivers probe function will be called.

Definition at line 424 of file bus.c.

void amba_driver_unregister ( struct amba_driver * drv )

amba_driver_unregister - remove an AMBA device driver : AMBA device driver structure to remove

Unregister an AMBA device driver from the Linux device model. The device model will call the drivers remove function for each device the device driver is currently handling.

read

amba_find_device - locate an AMBA device given a bus id : bus id for device (or NULL) : parent device (or NULL) : peripheral ID (or 0) : peripheral ID mask (or 0)

Return the AMBA device corresponding to the supplied parameters. If no device matches, returns NULL.

NOTE: When a valid device is found, its refcount is incremented, and must be decremented before the returned reference.
