Revert "pcmcia: add a new resource manager for non ISA systems"

This reverts commit 02b03846bb2befc558bfd0665749d6bb26f4c2f1.

Alan writes:
it seems there is a regression in there for some configuration of I/O
based devices. I'll take a look at it over the next couple of kernel
releases and see what is up then resubmit it with fixes.

Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2015-02-17T17:38:59+00:00

Pull ARM SoC driver updates from Olof Johansson:
 "These are changes for drivers that are intimately tied to some SoC and
  for some reason could not get merged through the respective subsystem
  maintainer tree.

  This time around, much of this is for at91, with the bulk of it being
  syscon and udc drivers.

  Also, there's:
   - coupled cpuidle support for Samsung Exynos4210
   - Renesas 73A0 common-clk work
   - of/platform changes to tear down DMA mappings on device destruction
   - a few updates to the TI Keystone knav code"

pcmcia: at91_cf: depend on !ARCH_MULTIPLATFORM

2015-01-29T18:58:09+00:00

Until the driver is corrected to stop including mach/at91_ramc.h and using
mach/io.h, it won't compile in a ARCH_MULTIPLATFORM configuration.

pcmcia: add missing include for new pci resource handler

2015-01-13T18:12:25+00:00

The recently added rsrc_pci.c file calls pci_bus_alloc_resource without
including the header file that declares it, and that sometimes causes
a build warning on ARM:

drivers/pcmcia/rsrc_pci.c: In function 'find_io_region':
drivers/pcmcia/rsrc_pci.c:40:2: error: implicit declaration of function 'pci_bus_alloc_resource' [-Werror=implicit-function-declaration]

This adds the missing include statement.

pcmcia: add a new resource manager for non ISA systems

2015-01-12T13:04:13+00:00

On a pure PCI platform we don't actually need all the complexity of the
rsrc_nonstatic manager, in fact we can just work directly with the pci
allocators and avoid all the complexity (and code bloat).

pcmcia: handle anonymous cards by generating a fake CIS

2015-01-12T13:04:12+00:00

The core pcmcia code blows up all over the place if it allowed a card without
a valid CIS. We need to allow such cards as the CIS stuff is not on the older
flash, ROM and SRAM cards.

In order to minimise the risk of misidentifying junk and feeding it to the
wrong thing we only fix up apparently anonymous cards if the driver for them
has been enabled.

pcmcia: Fix requery

2015-01-12T13:04:12+00:00

The requery logic goes off and attempts to read the CIS of empty slots. In
most cases this happens not to do any harm - but not all!

Add the missing check and also a WARN() to catch any other offenders.
