86 The event() function is this driver's Card Services event handler.
87 It will be called by Card Services when an appropriate card status
88 event is received. The config() and release() entry points are
89 used to configure or release a socket, in response to card
90 insertion and ejection events. They are invoked from the atmel_cs
94 static void atmel_config(dev_link_t *link);
95 static void atmel_release(dev_link_t *link);
96 static int atmel_event(event_t event, int priority,
97 event_callback_args_t *args);
100 The attach() and detach() entry points are used to create and destroy
101 "instances" of the driver, where each instance represents everything
102 needed to manage one actual PCMCIA card.
105 static dev_link_t *atmel_attach(void);
106 static void atmel_detach(dev_link_t *);
109 You'll also need to prototype all the functions that will actually
110 be used to talk to your device. See 'pcmem_cs' for a good example
111 of a fully self-sufficient driver; the other drivers rely more or
112 less on other parts of the kernel.
116 The dev_info variable is the "key" that is used to match up this
117 device driver with appropriate cards, through the card configuration
121 static dev_info_t dev_info = "atmel_cs";
124 A linked list of "instances" of the atmelnet device. Each actual
125 PCMCIA card corresponds to one device instance, and is described
126 by one dev_link_t structure (defined in ds.h).
128 You may not want to use a linked list for this -- for example, the
129 memory card driver uses an array of dev_link_t pointers, where minor
130 device numbers are used to derive the corresponding array index.
133 static dev_link_t *dev_list = NULL;
136 A dev_link_t structure has fields for most things that are needed
137 to keep track of a socket, but there will usually be some device
138 specific information that also needs to be kept track of. The
139 'priv' pointer in a dev_link_t structure can be used to point to
140 a device-specific private data structure, like this.
142 A driver needs to provide a dev_node_t structure for each device
143 on a card. In some cases, there is only one device per card (for
144 example, ethernet cards, modems). In other cases, there may be
145 many actual or logical devices (SCSI adapters, memory cards with
146 multiple partitions). The dev_node_t structures need to be kept
147 in a linked list starting at the 'dev' field of a dev_link_t
148 structure. We allocate them in the card's private data structure,
149 because they generally shouldn't be allocated dynamically.
151 In this case, we also provide a flag to indicate if a device is
152 "stopped" due to a power management event, or card ejection. The
153 device IO routines can use a flag like this to throttle IO to a
154 card that is not ready to accept it.

422 and accurate CIS. In practice, a driver usually "knows" most of
423 these things without consulting the CIS, and most client drivers
