NAME

       device_attach - try to attach device to a driver.

SYNOPSIS

       int device_attach(struct device * dev);

ARGUMENTS

       dev
	   device.

DESCRIPTION

       Walk the list of drivers that the bus has and call driver_probe_device for each pair. If a compatible pair is found, break out and return.

NAME

     DEVICE_ATTACH -- attach a device

SYNOPSIS

     #include <sys/param.h>
     #include <sys/bus.h>

     int
     DEVICE_ATTACH(device_t dev);

DESCRIPTION

     Attach a device to the system after the DEVICE_PROBE() method has been called and has indicated that the device exists.  The DEVICE_ATTACH()
     method should initialize the hardware and allocate other system resources (such as devfs(5) entries).

     Devices which implement busses should use this method to probe for the existence of devices attached to the bus and add them as children.	If
     this is combined with the use of bus_generic_attach(9) the child devices will be automatically probed and attached.

RETURN VALUES

     Zero is returned on success, otherwise an appropriate error is returned.
