2015-06-16pcmcia: do not break rsrc_nonstatic when handling anonymous cardsDominik Brodowski1-19/+9
Patch 1c6c9b1d9d25 caused a regression for rsrc_nonstatic: It relies on pccard_validate_cis() to determine whether an iomem resource can be used for PCMCIA cards. This override, however, lead invalid iomem resources to be accepted -- and lead to a fake CIS being used instead of the original CIS. To fix this issue, move the override for anonymous cards to the one place where it is needed -- when adding a PCMCIA device. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

2015-05-30pcmcia: Remove typedef tuple_flagsHimangi Saraogi1-6/+6
The Linux kernel coding style guidelines suggest not using typedefs for structure types. This patch gets rid of the typedef for tuple_flags.

2015-01-12pcmcia: handle anonymous cards by generating a fake CISAlan Cox1-4/+20
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.

2015-01-12pcmcia: Fix requeryAlan Cox1-1/+1
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!

2015-01-12pcmcia cis: on an out of range CIS read return 0xff, don't just warnAlan Cox1-1/+4
The current code displays warnings but then proceeds to try and reference the data through the PCMCIA window. Instead return 0xff. This prevents bogus CIS data sending us off into hyperspace.

2010-09-29pcmcia: convert pcmcia_request_configuration to pcmcia_enable_deviceDominik Brodowski1-1/+0
pcmcia_enable_device() now replaces pcmcia_request_configuration(). Instead of config_req_t, all necessary flags are either passed as a parameter to pcmcia_enable_device(), or (in rare circumstances) set in struct pcmcia_device -> flags. With the last remaining user of include/pcmcia/cs.h gone, remove all references.

pccard_validate_cis() nowadays destroys the CIS cache. Therefore, calling it after card setup should be avoided.

2010-01-17pcmcia: CardBus doesn't need CIS accessDominik Brodowski1-168/+32
At least no in-kernel CardBus-capable PCI driver makes use of the CIS access functions. Therefore, it seems sensible to remove this unused code, and cleanup cardbus.c a lot.

2010-01-17pcmcia: improve check for same card in slot after resumeDominik Brodowski1-0/+1
During a suspend/resume cycle, an user may change the card in the PCMCIA/CardBus slot. The pcmcia_core can at least look at the socket state to check whether it is the same. For PCMCIA devices, move the detection and handling of such a change to ds.c. For CardBus devices, the PCI hotplug interface doesn't offer a "rescan" facility which also _removes_ devices no longer to be found behind a bridge. Therefore, remove and re-add all devices unconditionally.

2009-11-08pcmcia: add new CIS access helpersDominik Brodowski1-0/+61
As a replacement to pcmcia_get_{first,next}_tuple() and pcmcia_get_tuple_data(), three new -- and easier to use -- functions are added: - pcmcia_get_tuple() to get the very first CIS entry of one type. - pcmcia_loop_tuple() to loop over all CIS entries of one type. - pcmcia_get_mac_from_cis() to read out the hardware MAC address from CISTPL_FUNCE. Only a handful of drivers need these functions anyway, as most CIS access is already handled by pcmcia_loop_config(), which now shares the same backed (pccard_loop_tuple()) with pcmcia_loop_tuple(). A pcmcia_get_mac_from_cis() bug noted by Komuro <komurojun-mbn@nifty.com> has been fixed in this revision. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2009-10-19pcmcia: pccard_read_tuple and TUPLE_RETURN_COMMON cleanupDominik Brodowski1-9/+11
pccard_read_tuple(), which is only used by the PCMCIA core, should handle TUPLE_RETURN_COMMON more sensibly: If a specific function (which may be 0) is requested, set tuple.Attributes = 0 as was done in all PCMCIA drivers. If, however, BIND_FN_ALL is requested, return the "common" tuple. As to the callers of pccard_read_tuple(): - All calls to pcmcia_validate_cis() had set the "function" parameter to BIND_FN_ALL. Therefore, remove the "function" parameter and make the parameter to pccard_read_tuple explicit. - Calls to CISTPL_VERS_1 and CISTPL_MANFID now set BIND_FN_ALL.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau1-1/+0
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).
