70 The event() function is this driver's Card Services event handler.
71 It will be called by Card Services when an appropriate card status
72 event is received. The config() and release() entry points are
73 used to configure or release a socket, in response to card
74 insertion and ejection events. They are invoked from the sedlbauer
78 static int sedlbauer_config(struct pcmcia_device *link) __devinit ;
79 static void sedlbauer_release(struct pcmcia_device *link);
82 The attach() and detach() entry points are used to create and destroy
83 "instances" of the driver, where each instance represents everything
84 needed to manage one actual PCMCIA card.

122 General socket configuration defaults can go here. In this
123 client, we assume very little, and rely on the CIS for almost
124 everything. In most clients, many details (i.e., number, sizes,
125 and attributes of IO windows) are fixed by the nature of the
126 device, and can be hard-wired here.

225 Now set up a common memory window, if needed. There is room
226 in the struct pcmcia_device structure for one memory window handle,
227 but if the base addresses need to be saved, or if multiple
228 windows are needed, the info should go in the private data
229 structure for this device.
231 Note that the memory window base is a physical address, and
232 needs to be mapped to virtual space with ioremap() before it

268 In this loop, we scan the CIS for configuration table entries,
269 each of which describes a valid card configuration, including
270 voltage, IO window, memory window, and interrupt settings.
272 We make no assumptions about the card to be configured: we use
273 just the information available in the CIS. In an ideal world,
274 this would work for any PCMCIA card, but it requires a complete
275 and accurate CIS. In practice, a driver usually "knows" most of
276 these things without consulting the CIS, and most client drivers
277 will only use the CIS to fill in implementation-defined details.
279 ret = pcmcia_loop_config(link, sedlbauer_config_check, req);
284 This actually configures the PCMCIA socket -- setting up
285 the I/O windows and the interrupt mapping, and putting the
286 card and host interface into "Memory and IO" mode.
