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

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