[David Young <dyoung%netbsd.org@localhost>]

Module Name:    src
Committed By:   dyoung
Date:           Sun Dec 16 21:14:22 UTC 2007

Modified Files:
        src/sys/arch/i386/pci: elan520.c

Log Message:
Miscellaneous changes designed to improve elansc suspend/detachment:

1 Synchronize access to the softc and hardware with a mutex.
2 Add the sc_suspended flag, and observe it in the watchdog routines.
3 Re-order operations in elansc_attach() and elansc_detach() to
  protect against access while the device is not fully configured.
4 Cancel detachment if sysmon_wdog_unregister() is cancelled by a
  signal.
5 Add an empty childdetached method so that I can detach gpio0 at
  elansc0.  (XXX cannot individually re-attach gpio0.)
