3b27e9421a [PATCH] pcmcia: properly handle static mem, but dynamic io sockets
Some PCMCIA sockets have statically mapped memory windows, but dynamically
mapped IO windows. Using the "nonstatic" socket library is inpractical for
them, as they do neither need a resource database (as we can trust the
kernel resource database on m68k and ppc) nor lots of other features of that
library. Let them get a small "iodyn" socket library (105 lines of code)
instead.

f8cfa618dc [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);

The Sharp SL-Cxx00 models have a combined power control for the SD

machines to provide a custom control function for this and such a
function is added for spitz/akita/borzoi.

It also moves the gpio init code into the machine files as this
is machine dependent and differs between some models. A couple of

- avoid usage of non-standard "uint/uchar" data types

a413c09094 [PATCH] yenta: don't mess with bridge control register
In interrupt probing (both ISA and PCI) the bridge control register is used
to change interrupt routing to ISA or PCI by changing bit 7.  But this bit
only controls the routing of card functional interrupts, not the CSC
interrupts which are used for interrupt probing.

A bad side effect of messing with this register in yenta_probe_irq() is
that it can lead to irq storms if a card is inserted and already powered by
the BIOS.

Usage in yenta_sock_init() and yenta_config_init() seem to be fishy as well.

The patch adds a hook in cb_alloc() that allows special tuning for the

ea2f1590aa [PATCH] yenta: make ToPIC95 bridges work with 16bit cards
ToPIC95 brides (and maybe some other too) require to use the ExCA registers
to power up the socket if a 16bit card is pluged.  allow socket drivers to
set a flag so that yenta does just that.  also clean up yenta_get_status()
a bit to use the new yenta_get_power() function.

Side note: ToPIC97 bridges (at least in Rev.5 i have) don't require this.

Ryan Underwood <nemesis-lists@icequake.net> said:

 According to the mail that David Hinds received from a Toshiba engineer,
 ToPIC95 and 97 do require this, and ToPIC100 does not.  Maybe you have a
 later revision.

 For all chips, 16-bit cards can be enabled through ExCA.  So doesn't it
 make sense just to make this the default behavior for all Toshiba chips,
 to avoid corner cases showing up later?

Daniel responded:

 I disagree with ryan to change anything for topic97 bridges.  they work.
 and I couldn't find (read google) any report of a topic97 breaking on
 applying power with the CB registers.

 I'm having several toshba notebooks at work (and home) with topic95,97,100
 bridges.  Only the ones with a topic95 didn't work.

f7d1d23c30 [PATCH] Obvious bugfix for yenta resource allocation
Recent changes (well, dating from 12 July) have broken cardbus on my
powerbook: I get 3 messages saying "no resource of type xxx available,
trying to continue", and if I plug in my wireless card, it complains
that there are no resources allocated to the card.  This all worked in
2.6.12.

Looking at the code in yenta_socket.c, function yenta_allocate_res,
it's obvious what is wrong: if we get to line 639 (i.e. there wasn't a
usable preassigned resource), we will always flow through to line 668,
which is the printk that I was seeing, even if a resource was
successfully allocated.  It looks to me as though there should be a
return statement after the two config_writel's in each of the 3
branches of the if statements, so that the function returns after
successfully setting up the resource.

The patch below adds these return statements, and with this patch,
cardbus works on my powerbook once again.

to disable read prefetch and write burst on those old bridges.

a1b274fbe3 [PATCH] pcmcia: fix sharing IRQs and request_irq without IRQ_HANDLE_PRESENT
Debugging and description from: Noah Misch <noah@cs.caltech.edu>

When a driver calls pcmcia_request_irq with IRQ_HANDLE_PRESENT unset, it looks
for an open IRQ by request_irq()ing with a dummy handler and NULL dev_info.
free_irq uses dev_info as a key for identifying the handler to free among
those sharing an IRQ, so request_irq returns -EINVAL if dev_info is NULL and
the IRQ may be shared.  That unknown error code is the -EINVAL.

It looks like only pcnet_cs and axnet_cs are affected.  Most other drivers let
pcmcia_request_irq install their interrupt handlers.  sym53c500_cs requests
its IRQ manually, but it cannot share an IRQ.

The appended patch changes pcmcia_request_irq to pass an arbitrary, unique,
non-NULL dev_info with the dummy handler.

a00db1ba7c [PATCH] pcmcia: remove client services version
The Linux PCMCIA code has some data that was apparently used (or meant to be
used) to ensure that only proper client drivers are loaded.  This is now
ensured (to a certain degree) by the fact that the most client drivers are
part of the kernel.  Also, the version information has not been updated
despite major changes in PCMCIA API.  This has made it meaningless.

This patch removes servinfo_t and pcmcia_get_card_services_info.  They are not
used in any userspace utilities such as pcmcia-cs and pcmciautils.
drivers/pcmcia/pcmcia_ioctl.c is adjusted accordingly.

CS_RELEASE and CS_RELEASE_CODE are removed.  include/pcmcia/version.h is empty
now.  It will be removed later, but for now it's left in the tree to avoid
touching all PCMCIA clients.

The only driver that needs to be changed is drivers/scsi/pcmcia/nsp_cs.c,
which uses CS_RELEASE_CODE.

69a4d56bae [PATCH] pcmcia: fix i82365 request_region double usage
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=f354942cb301fed273f423fb5c4f57bde3efc5b2
converted the check_region() calls in drivers/pcmcia/i82365.c into
request_regions.  Unfortunately this seems to have broken things.

isa_probe() used to call check_region() and then call add_pcic() which would
request_region().

Now isa_probe() calls request_region() and then calls add_pcic() which calls
request_region() again, this fails and add_pcic() returns immediately without
doing all the setup etc.

On the face of it the patch below fixes the problem, by not doing the second
request region in add_pcic().  I think this is preferable to remove the call
in isa_probe() since identify() touches the I/O regions and is called before
add_pcic().

However I haven't fully grokked the meaning of the code which follows the
request_region() in isa_probe(), so I'm not sure that the handling WRT
multiple sockets and multiple bridge chips is correct.  In particular I'm not
convinced that the regions for subsequent sockets and/or bridges will be
requested at all.  I suspect a more thorough reworking by someone who
understands what is going on there might be in order.

I should mention that I'm actually messing about with this on an ARM platform
with wacky memory and i/o mapping offsets etc, it doesn't quite work yet for
other reasons which preclude full testing etc, but I think the problem above
is still present for more normal x86 stuff.

b6d00f0de9 [PATCH] ACPI-based PCI resources: PCMCIA bugfix, but resources missing in trees
Don't auto-configure yenta sockets for PCMCIA devices if it is connected to
the root PCI bus on the x86 or x86_64 architectures.  Previously, this was
handled by the "ioport_resource"/"iomem_resource" check a few lines below,
but with the new ACPI-based resource handling this doesn't catch all cases
any longer.

pci-yenta-cardbus-fix.patch and this patch should solve the initialization
time trouble.  However, the ACPI-based PCI resource handling is badly
broken, IMHO:

- many resources of devices don't show up in the resource trees (
  /proc/iomem and /proc/ioports) any longer. This means that PCMCIA, but
  also possibly other subsystems (ISA, PnP, ...) do not know which resources
  it cannot use.

- verify_root_windows() should fail if there are no iomem _or_ ioport
  resources, not only if there are no iomem _and_ ioport resources.

57b6281cea [PATCH] pcmcia: 8 and 16 bit access for static_map
The PCMCIA card services layer is never setting the i/o map attributes when
SS_CAP_STATIC_MAP is specified.  Net result, sockets' set_io_map() calls
always see requests with most flags clear, meaning 8 bit access.

For hardware that always autosizes, that won't matter; and all current
STATIC_MAP drivers ignore those attributes.  A new driver (for at91rm9200)
suffers badly from this, since this forces everything into 8 bit mode and
that breaks both (a) cards requiring 16 bit access, and (b) ide-cs; but of
course 8-bit cards work OK (as does accessing card attributes).

So this patch arranges to pass the attributes down, matching the behavior
for non-static mappings (using the first/only I/O window).
