10 automatically, though the driver may still
11 in the callback function. The following aut
12 are provided at the moment:

15 - CONF_AUTO_SET_VPP : set Vpp
16 - CONF_AUTO_AUDIO : auto-enable au
17 - CONF_AUTO_SET_IO : set ioport res
18 - CONF_AUTO_SET_IOMEM : set first iome

20 * pcmcia_request_configuration -> pcmcia_enabl
21 pcmcia_request_configuration() got renamed
22 as it mirrors pcmcia_disable_device(). Conf
23 stored in struct pcmcia_device, e.g. in the
24 config_index, config_base, vpp.
25
26 * pcmcia_request_window changes (as of 2.6.36)
27 Instead of win_req_t, drivers are now reque
28 `struct pcmcia_device *p_dev->resource[2,3,
29 ranges. After a call to pcmcia_request_wind

32
33 * pcmcia_request_io changes (as of 2.6.36)
34 Instead of io_req_t, drivers are now reques
35 `struct pcmcia_device *p_dev->resource[0,1]
36 ranges. After a call to pcmcia_request_io()

39
40 * No dev_info_t, no cs_types.h (as of 2.6.36)
41 dev_info_t and a few other typedefs are rem
42 in PCMCIA device drivers. Also, do not incl

44
45 * No dev_node_t (as of 2.6.35)
46 There is no more need to fill out a "dev_no
47
48 * New IRQ request rules (as of 2.6.35)
49 Instead of the old pcmcia_request_irq() int
50 choose between:
51
52 - calling request_irq/free_irq directly. Us
53 - use pcmcia_request_irq(p_dev, handler_t);
54 clean up automatically on calls to pcmcia
55 device ejection.
56
57 * no cs_error / CS_CHECK / CONFIG_PCMCIA_DEBUG
58 Instead of the cs_error() callback or the C
59 Linux-style checking of return values, and
60 messages using "dev_dbg()" or "pr_debug()".
61
62 * New CIS tuple access (as of 2.6.33)
63 Instead of pcmcia_get_{first,next}_tuple(),
64 pcmcia_parse_tuple(), a driver shall use "p
65 only interested in one (raw) tuple, or "pcm
66 interested in all tuples of one type. To de

69 * New configuration loop helper (as of 2.6.28)
70 By calling pcmcia_loop_config(), a driver c
71 configuration options. During a driver's pr
72 to use pcmcia_get_{first,next}_tuple, pcmci

76 Instead of calling pcmcia_release_{configur
77 necessary now is calling pcmcia_disable_dev
78 reason left to call pcmcia_release_io and p
79 exports for them were removed.
80
81 * Unify detach and REMOVAL event code, as well
82 code (as of 2.6.16)::
83
84 void (*remove) (struct pcmcia_

95 * event handler initialization in struct pcmci
96 The event handler is notified of all events
97 as the event() callback in the driver's str
98
99 * pcmcia/version.h should not be used (as of 2

102 * in-kernel device<->driver matching (as of 2.

105
106 * Device model integration (as of 2.6.11)
107 A struct pcmcia_device is registered with t
108 and can be used (e.g. for SET_NETDEV_DEV) b
109 handle_to_dev(client_handle_t * handle).
110
111 * Convert internal I/O port addresses to unsig
112 ioaddr_t should be replaced by unsigned int
113
114 * irq_mask and irq_list parameters (as of 2.6.
115 The irq_mask and irq_list parameters should
116 PCMCIA card drivers. Instead, it is the job
117 determine which IRQ should be used. Therefo
118 is ignored.
119
120 * client->PendingEvents is gone (as of 2.6.11)
121 client->PendingEvents is no longer availabl
122
123 * client->Attributes are gone (as of 2.6.11)
124 client->Attributes is unused, therefore it
125 PCMCIA card drivers
126
127 * core functions no longer available (as of 2.
128 The following functions have been removed f
129 because they are unused by all in-kernel dr
130 driver was reported to rely on them::
131
132 pcmcia_get_first_region()
133 pcmcia_get_next_region()
134 pcmcia_modify_window()
135 pcmcia_set_event_mask()
136 pcmcia_get_first_window()
137 pcmcia_get_next_window()

139 * device list iteration upon module removal (a
140 It is no longer necessary to iterate on the
141 client list and call the ->detach() functio
142
143 * Resource management. (as of 2.6.8)
144 Although the PCMCIA subsystem will allocate
145 it no longer marks these resources busy. Th
146 authors are now responsible for claiming yo
147 other drivers in Linux. You should use requ
148 your IO regions in-use, and request_mem_reg
149 memory regions in-use. The name argument sh
150 your driver name. Eg, for pcnet_cs, name sh
151 string "pcnet_cs".
152
153 * CardServices is gone
154 CardServices() in 2.4 is just a big switch s
155 services. In 2.6, all of those entry points
156 directly (except for pcmcia_report_error(),
157
158 * struct pcmcia_driver
159 You need to use struct pcmcia_driver and pcm
160 instead of {un,}register_pccard_driver
