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

PCMCIA card corresponds to one device instance, and is described

memory card driver uses an array of struct pcmcia_device pointers, where minor
device numbers are used to derive the corresponding array index.

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 can't be allocated dynamically.

help
If you say Y here, the deprecated ioctl interface to the PCMCIA
subsystem will be built. It is needed by the deprecated pcmcia-cs
tools (cardmgr, cardctl) to function properly.
You should use the new pcmciautils package instead (see
<file:Documentation/Changes> for location and details).
This config option will most likely be removed from kernel 2.6.35,
the associated code from kernel 2.6.36.
As the PCMCIA ioctl is not locking safe, it depends on !SMP and
!PREEMPT.
If unsure, say N.
