97 | A driver needs to provide a dev_node_t structure for each device |
98 | on a card. In some cases, there is only one device per card (for | |
99 | example, ethernet cards, modems). In other cases, there may be | |
100 | many actual or logical devices (SCSI adapters, memory cards with | |
101 | multiple partitions). The dev_node_t structures need to be kept | |
fba395ee | 102 | in a linked list starting at the 'dev' field of a struct pcmcia_device |
1da177e4 LT |
103 | structure. We allocate them in the card's private data structure, |
104 | because they generally shouldn't be allocated dynamically. | |
105 | ||
106 | In this case, we also provide a flag to indicate if a device is | |
107 | "stopped" due to a power management event, or card ejection. The | |
108 | device IO routines can use a flag like this to throttle IO to a | |
109 | card that is not ready to accept it. | |
