 This file details changes in 2.6 which affect PCMCIA card driver authors:
+* No dev_node_t (as of 2.6.35)
+   There is no more need to fill out a "dev_node_t" structure.
+
+* New IRQ request rules (as of 2.6.35)
+   Instead of the old pcmcia_request_irq() interface, drivers may now
+   choose between:
+   - calling request_irq/free_irq directly. Use the IRQ from *p_dev->irq.
+   - use pcmcia_request_irq(p_dev, handler_t); the PCMCIA core will
+     clean up automatically on calls to pcmcia_disable_device() or
+     device ejection.
+   - drivers still not capable of IRQF_SHARED (or not telling us so) may
+     use the deprecated pcmcia_request_exclusive_irq() for the time
+     being; they might receive a shared IRQ nonetheless.
 
 * no cs_error / CS_CHECK / CONFIG_PCMCIA_DEBUG (as of 2.6.33)
    Instead of the cs_error() callback or the CS_CHECK() macro, please use

-   A driver needs to provide a dev_node_t structure for each device

-   example, ethernet cards, modems).  In other cases, there may be
-   many actual or logical devices (SCSI adapters, memory cards with
-   multiple partitions).  The dev_node_t structures need to be kept
-   in a linked list starting at the 'dev' field of a struct pcmcia_device
-   structure.  We allocate them in the card's private data structure,
-   because they generally shouldn't be allocated dynamically.
-   In this case, we also provide a flag to indicate if a device is
-   "stopped" due to a power management event, or card ejection.  The
-   device IO routines can use a flag like this to throttle IO to a
-   card that is not ready to accept it.
