| * pcmcia: validate late-added resourcesDominik Brodowski2010-02-25
| | | | | | | | | | | | | | | | | | | | | | Currently, only those mem resources are validated which are already registered at the time the first PCMCIA card is inserted. As we can only validate resources immediately after card insert, store "registered" mem resources in mem_db, and only upon validation move them to mem_db_valid. When allocationg mem resources, mem_db_valid is then preferred to mem_db. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
| * pcmcia: allow for extension of resource intervalDominik Brodowski2010-02-17

| * pcmcia: remove useless msleep in ds.cDominik Brodowski2010-02-17
| | | | | | | | | | | | | | | | | | As this is the socket thread (pccardd) starting up, we do not have anything to wait for in ds.c. Instead, wait the same amount of time in pccardd to allow userspace to catch up and - possibly - execute pcmcia-socket-startup. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | platform_get_irq returns -ENXIO on failure, so !irq was probably always true. Better use irq <= 0. Note that a return value of zero is still handled as error even though this could mean irq0. This is a followup to 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that changed the return value of platform_get_irq from 0 to -ENXIO on error.

| * pcmcia/yenta: add module parameter for O2 speedupsWolfram Sang2010-02-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | O2-bridges can do read prefetch and write burst. However, for some combinations of older bridges and cards, this causes problems, so it is disabled for those bridges. Now, as some users know their setup works with the speedups enabled, a new parameter is introduced to the driver. Now, a user can specifically enable or disable these features, while the default is what we have today: detect the bridge and decide accordingly. Fixes Bugzilla entry 15014. Simplify and unify the printouts, fix a whitespace issue while we are here.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
