# Companion interface for pccard. We need to set attributes for memory
# and i/o port mappings (as well as other types of attributes) that have
# a well defined meaning inside the pccard/cardbus system. The bus
# methods are inadequate for this because this must be done at the time the
# resources are set for the device, which predates their activation. Also,
# the driver activating the resources doesn't necessarily know or need to know
# these attributes.

# 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.
