+Matching of PCMCIA devices to drivers is done using one or more of the
+following criteria:
+
+- manufactor ID
+- card ID
+- product ID strings _and_ hashes of these strings
+- function ID
+- device function (actual and pseudo)
+
+You should use the helpers in include/pcmcia/device_id.h for generating the
+struct pcmcia_device_id[] entries which match devices to drivers.
+
+If you want to match product ID strings, you also need to pass the crc32
+hashes of the string to the macro, e.g. if you want to match the product ID
+string 1, you need to use
+
+PCMCIA_DEVICE_PROD_ID1("some_string", 0x(hash_of_some_string)),
+
+If the hash is incorrect, the kernel will inform you about this in "dmesg"
+upon module initialization, and tell you of the correct hash.
+
+You can determine the hash of the product ID strings by catting the file
+"modalias" in the sysfs directory of the PCMCIA device. It generates a string
+in the following form:
+pcmcia:m0149cC1ABf06pfn00fn00pa725B842DpbF1EFEE84pc0877B627pd00000000
+
+The hex value after "pa" is the hash of product ID string 1, after "pb" for
+string 2 and so on.
+
+Alternatively, you can use crc32hash (see tools/pcmcia/crc32hash.c)
+to determine the crc32 hash. Simply pass the string you want to evaluate
+as argument to this program, e.g.:
+$ tools/pcmcia/crc32hash "Dual Speed"

+This file details changes in 2.6 which affect PCMCIA card driver authors:
+* pcmcia_loop_config() and autoconfiguration (as of 2.6.36)
+ If struct pcmcia_device *p_dev->config_flags is set accordingly,
+ pcmcia_loop_config() now sets up certain configuration values
+ automatically, though the driver may still override the settings
+ in the callback function. The following autoconfiguration options
+ are provided at the moment:
+ CONF_AUTO_CHECK_VCC : check for matching Vcc
+ CONF_AUTO_SET_VPP : set Vpp
+ CONF_AUTO_AUDIO : auto-enable audio line, if required
+ CONF_AUTO_SET_IO : set ioport resources (->resource[0,1])
+ CONF_AUTO_SET_IOMEM : set first iomem resource (->resource[2])
+
+* pcmcia_request_configuration -> pcmcia_enable_device (as of 2.6.36)
+ pcmcia_request_configuration() got renamed to pcmcia_enable_device(),
+ as it mirrors pcmcia_disable_device(). Configuration settings are now
+ stored in struct pcmcia_device, e.g. in the fields config_flags,
+ config_index, config_base, vpp.
+
+* pcmcia_request_window changes (as of 2.6.36)
+ Instead of win_req_t, drivers are now requested to fill out
+ struct pcmcia_device *p_dev->resource[2,3,4,5] for up to four ioport
+ ranges. After a call to pcmcia_request_window(), the regions found there
+ are reserved and may be used immediately -- until pcmcia_release_window()
+ is called.
+
+* pcmcia_request_io changes (as of 2.6.36)
+ Instead of io_req_t, drivers are now requested to fill out
+ struct pcmcia_device *p_dev->resource[0,1] for up to two ioport
+ ranges. After a call to pcmcia_request_io(), the ports found there
+ are reserved, after calling pcmcia_request_configuration(), they may
+ be used.
+
+* No dev_info_t, no cs_types.h (as of 2.6.36)
+ dev_info_t and a few other typedefs are removed. No longer use them
+ in PCMCIA device drivers. Also, do not include pcmcia/cs_types.h, as
+ this file is gone.
+
+* No dev_node_t (as of 2.6.35)
+ There is no more need to fill out a "dev_node_t" structure.
+
+* New IRQ request rules (as of 2.6.35)
+ Instead of the old pcmcia_request_irq() interface, drivers may now
+ choose between:
+ - calling request_irq/free_irq directly. Use the IRQ from *p_dev->irq.
+ - use pcmcia_request_irq(p_dev, handler_t); the PCMCIA core will
+ clean up automatically on calls to pcmcia_disable_device() or
+ device ejection.
+ - drivers still not capable of IRQF_SHARED (or not telling us so) may
+ use the deprecated pcmcia_request_exclusive_irq() for the time
+ being; they might receive a shared IRQ nonetheless.
+
+* 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.
+
+* Device model integration (as of 2.6.11)
+ A struct pcmcia_device is registered with the device model core,
+ 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 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
+ PCMCIA card drivers. Instead, it is the job of the PCMCIA core to
+ determine which IRQ should be used. Therefore, link->irq.IRQInfo2
+ is ignored.
+
+* client->PendingEvents is gone (as of 2.6.11)
+ client->PendingEvents is no longer available.
+
+* client->Attributes are gone (as of 2.6.11)
+ client->Attributes is unused, therefore it is removed from all
+ PCMCIA card drivers
+
+* core functions no longer available (as of 2.6.11)
+ The following functions have been removed from the kernel source
+ because they are unused by all in-kernel drivers, and no external
+ driver was reported to rely on them:
+ pcmcia_get_first_region()
+ pcmcia_get_next_region()
+ pcmcia_modify_window()
+ pcmcia_set_event_mask()
+ pcmcia_get_first_window()
+ pcmcia_get_next_window()
+
+* device list iteration upon module removal (as of 2.6.10)
+ It is no longer necessary to iterate on the driver's internal
+ client list and call the ->detach() function upon module removal.
+
+* Resource management. (as of 2.6.8)
+ Although the PCMCIA subsystem will allocate resources for cards,
+ it no longer marks these resources busy. This means that driver
+ authors are now responsible for claiming your resources as per
+ other drivers in Linux. You should use request_region() to mark
+ your IO regions in-use, and request_mem_region() to mark your
+ 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

+PCMCIA Driver
+-------------
+
+
+sysfs
+-----
+
+New PCMCIA IDs may be added to a device driver pcmcia_device_id table at
+runtime as shown below:
+
+echo "match_flags manf_id card_id func_id function device_no \
+prod_id_hash[0] prod_id_hash[1] prod_id_hash[2] prod_id_hash[3]" > \
+/sys/bus/pcmcia/drivers/{driver}/new_id
+
+All fields are passed in as hexadecimal values (no leading 0x).
+The meaning is described in the PCMCIA specification, the match_flags is
+a bitwise or-ed combination from PCMCIA_DEV_ID_MATCH_* constants
+defined in include/linux/mod_devicetable.h.
+
+Once added, the driver probe routine will be invoked for any unclaimed
+PCMCIA device listed in its (newly updated) pcmcia_device_id list.
+
+A common use-case is to add a new device according to the manufacturer ID
+and the card ID (form the manf_id and card_id file in the device tree).
+For this, just use:
+
+echo "0x3 manf_id card_id 0 0 0 0 0 0 0" > \
+ /sys/bus/pcmcia/drivers/{driver}/new_id
+
+after loading the driver.

+- skt_mutex - serializes card insert / ejection
+ - ops_mutex - serializes socket operation
+
+

+ socket_reset()
+ socket_shutdown()
+ socket_setup()
+ socket_remove()
+ socket_insert()
+ socket_early_resume()
+ socket_late_resume()
