Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

/*======================================================================
A PCMCIA token-ring driver for IBM-based cards
This driver supports the IBM PCMCIA Token-Ring Card.
Written by Steve Kipisz, kipisz@vnet.ibm.com or
bungy@ibm.net
Written 1995,1996.
This code is based on pcnet_cs.c from David Hinds.
V2.2.0 February 1999 - Mike Phillips phillim@amtrak.com
Linux V2.2.x presented significant changes to the underlying
ibmtr.c code. Mainly the code became a lot more organized and
modular.
This caused the old PCMCIA Token Ring driver to give up and go
home early. Instead of just patching the old code to make it
work, the PCMCIA code has been streamlined, updated and possibly
improved.
This code now only contains code required for the Card Services.
All we do here is set the card up enough so that the real ibmtr.c
driver can find it and work with it properly.
i.e. We set up the io port, irq, mmio memory and shared ram
memory. This enables ibmtr_probe in ibmtr.c to find the card and
configure it as though it was a normal ISA and/or PnP card.
CHANGES
v2.2.5 April 1999 Mike Phillips (phillim@amtrak.com)
Obscure bug fix, required changed to ibmtr.c not ibmtr_cs.c
v2.2.7 May 1999 Mike Phillips (phillim@amtrak.com)
Updated to version 2.2.7 to match the first version of the kernel
that the modification to ibmtr.c were incorporated into.
v2.2.17 July 2000 Burt Silverman (burts@us.ibm.com)
Address translation feature of PCMCIA controller is usable so
memory windows can be placed in High memory (meaning above
0xFFFFF.)

[PATCH] pcmcia: new suspend core Move the suspend and resume methods out of the event handler, and into special functions. Also use these functions for pre- and post-reset, as almost all drivers already do, and the remaining ones can easily be converted.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe callback Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified probe() callback. As all in-kernel drivers are changed to this new callback, there will be no temporary backwards-compatibility. Inside a probe() function, each driver _must_ set struct pcmcia_device *p_dev->instance and instance->handle correctly. With these patches, the basic driver interface for 16-bit PCMCIA drivers now has the classic four callbacks known also from other buses: int (*probe) (struct pcmcia_device *dev); void (*remove) (struct pcmcia_device *dev); int (*suspend) (struct pcmcia_device *dev); int (*resume) (struct pcmcia_device *dev); Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
