This file details changes in 2.6 which affect PCMCIA card driver authors:
-* in-kernel device<->driver matching
+* no cs_error / CS_CHECK / CONFIG_PCMCIA_DEBUG (as of 2.6.33)
+ Instead of the cs_error() callback or the CS_CHECK() macro, please use
+ Linux-style checking of return values, and -- if necessary -- debug
+ messages using "dev_dbg()" or "pr_debug()".
+
+* New CIS tuple access (as of 2.6.33)
+ Instead of pcmcia_get_{first,next}_tuple(), pcmcia_get_tuple_data() and
+ pcmcia_parse_tuple(), a driver shall use "pcmcia_get_tuple()" if it is
+ only interested in one (raw) tuple, or "pcmcia_loop_tuple()" if it is
+ interested in all tuples of one type. To decode the MAC from CISTPL_FUNCE,
+ a new helper "pcmcia_get_mac_from_cis()" was added.
+
+* New configuration loop helper (as of 2.6.28)
+ By calling pcmcia_loop_config(), a driver can iterate over all available
+ configuration options. During a driver's probe() phase, one doesn't need
+ to use pcmcia_get_{first,next}_tuple, pcmcia_get_tuple_data and
+ pcmcia_parse_tuple directly in most if not all cases.
+
+* New release helper (as of 2.6.17)
+ Instead of calling pcmcia_release_{configuration,io,irq,win}, all that's
+ necessary now is calling pcmcia_disable_device. As there is no valid
+ reason left to call pcmcia_release_io and pcmcia_release_irq, the
+ exports for them were removed.
+
+* Unify detach and REMOVAL event code, as well as attach and INSERTION
+ code (as of 2.6.16)
+ void (*remove) (struct pcmcia_device *dev);
+ int (*probe) (struct pcmcia_device *dev);
+
+* Move suspend, resume and reset out of event handler (as of 2.6.16)
+ int (*suspend) (struct pcmcia_device *dev);
+ int (*resume) (struct pcmcia_device *dev);
+ should be initialized in struct pcmcia_driver, and handle
+ (SUSPEND == RESET_PHYSICAL) and (RESUME == CARD_RESET) events
+
+* event handler initialization in struct pcmcia_driver (as of 2.6.13)
+ The event handler is notified of all events, and must be initialized
+ as the event() callback in the driver's struct pcmcia_driver.
+
+* pcmcia/version.h should not be used (as of 2.6.13)
+ This file will be removed eventually.
+
+* in-kernel device<->driver matching (as of 2.6.13)
PCMCIA devices and their correct drivers can now be matched in
kernelspace. See 'devicetable.txt' for details.
and can be used (e.g. for SET_NETDEV_DEV) by using
handle_to_dev(client_handle_t * handle).
-* Convert internal I/O port addresses to unsigned long (as of 2.6.11)
- ioaddr_t should be replaced by kio_addr_t in PCMCIA card drivers.
+* Convert internal I/O port addresses to unsigned int (as of 2.6.11)
+ ioaddr_t should be replaced by unsigned int in PCMCIA card drivers.
* irq_mask and irq_list parameters (as of 2.6.11)
The irq_mask and irq_list parameters should no longer be used in
memory regions in-use. The name argument should be a pointer to
your driver name. Eg, for pcnet_cs, name should point to the
string "pcnet_cs".
+
+* CardServices is gone
+ CardServices() in 2.4 is just a big switch statement to call various
+ services. In 2.6, all of those entry points are exported and called
+ directly (except for pcmcia_report_error(), just use cs_error() instead).
+
+* struct pcmcia_driver
+ You need to use struct pcmcia_driver and pcmcia_{un,}register_driver
+ instead of {un,}register_pccard_driver
