* linux/drivers/ide/pci/delkin_cb.c
*
* Created 20 Oct 2004 by Mark Lord
*
* Basic support for Delkin/ASKA/Workbit Cardbus CompactFlash adapter
*
* Modeled after the 16-bit PCMCIA driver: ide-cs.c
*
* This is slightly peculiar, in that it is a PCI driver,
* but is NOT an IDE PCI driver -- the IDE layer does not directly
* support hot insertion/removal of PCI interfaces, so this driver
* is unable to use the IDE PCI interfaces. Instead, it uses the
* same interfaces as the ide-cs (PCMCIA) driver uses.
* On the plus side, the driver is also smaller/simpler this way.
*
* This file is subject to the terms and conditions of the GNU General Public
* License. See the file COPYING in the main directory of this archive for

* HACKITY HACK

* This is a workaround for the limitation 5 of the TC86C001 IDE controller:
* if a DMA transfer terminates prematurely, the controller leaves the device's
* interrupt request (INTRQ) pending and does not generate a PCI interrupt (or
* set the interrupt bit in the DMA status register), thus no PCI interrupt
* will occur until a DMA transfer has been successfully completed.
*
* We work around this by initiating dummy, zero-length DMA transfer on
* a DMA timeout expiration. I found no better way to do this with the current
* IDE core than to temporarily replace a higher level driver's timer expiry
* handler with our own backing up to that handler in case our recovery fails.
