# Compatibility methods for OLDCARD drivers. We use these routines to make
|
|
# it possible to call the OLDCARD driver's probe routine in the context that
|
|
# it expects. For OLDCARD these are implemented as pass throughs to the
|
|
# device_{probe,attach} routines. For NEWCARD they are implemented such
|
|
# such that probe becomes strictly a matching routine and attach does both
|
|
# the old probe and old attach.
|
|
#
|
|
# compat devices should use the following:
|
|
#
|
|
# /* Device interface */
|
|
# DEVMETHOD(device_probe), pccard_compat_probe),
|
|
# DEVMETHOD(device_attach), pccard_compat_attach),
|
|
# /* Card interface */
|
|
# DEVMETHOD(card_compat_match, foo_match), /* newly written */

# DEVMETHOD(card_compat_probe, foo_probe), /* old probe */
|
|
# DEVMETHOD(card_compat_attach, foo_attach), /* old attach */
|
|
#
|
|
# This will allow a single driver binary image to be used for both
|
|
# OLDCARD and NEWCARD.
|
|
#
|
|
# Drivers wishing to not retain OLDCARD compatibility needn't do this.
|
|
#
|
|
# The compat_do_* versions are so that we can make the pccard_compat_probe
|
|
# and _attach static lines and have the bus system pick the right version
|
|
# to use so we don't enshrine pccard_* symbols in the driver's module.
