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

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

227 In this loop, we scan the CIS for configuration table entries,
228 each of which describes a valid card configuration, including
229 voltage, IO window, memory window, and interrupt settings.
231 We make no assumptions about the card to be configured: we use
232 just the information available in the CIS. In an ideal world,
233 this would work for any PCMCIA card, but it requires a complete
234 and accurate CIS. In practice, a driver usually "knows" most of
235 these things without consulting the CIS, and most client drivers
236 will only use the CIS to fill in implementation-defined details.
