pcmcia: Use pci_is_bridge() to simplify code

2014-05-27T20:58:24+00:00

Use pci_is_bridge() to simplify code. No functional change. Requires: 326c1cdae741 PCI: Rename pci_is_bridge() to pci_has_subordinate() Requires: 1c86438c9423 PCI: Add new pci_is_bridge() interface Signed-off-by: Yijing Wang Signed-off-by: Bjorn Helgaas

pcmcia: Use global PCI rescan-remove locking

2014-01-14T19:14:25+00:00

Multiple race conditions are possible between the cardbus PCI device addition and removal and the generic PCI bus rescan and device removal that can be triggered via sysfs. To avoid those race conditions make the cardbus code use global PCI rescan-remove locking. Signed-off-by: Rafael J. Wysocki Signed-off-by: Bjorn Helgaas

PCI: Delay enabling bridges until they're needed

2013-07-25T18:35:03+00:00

We currently enable PCI bridges after scanning a bus and assigning resources. This is often done in arch code. This patch changes this so we don't enable a bridge until necessary, i.e., until we enable a PCI device behind the bridge. We do this in the generic pci_enable_device() path, so this also removes the arch-specific code to enable bridges. [bhelgaas: changelog] Signed-off-by: Yinghai Lu Signed-off-by: Bjorn Helgaas

pcmcia: Use common pci_stop_and_remove_bus_device()

2012-08-22T17:31:20+00:00

Use pci_stop_and_remove_bus_device() like most other hotplug drivers rather than the special-purpose "behind_bridge" variant. This just means we have to iterate through all the devices downstream of the bridge ourselves, which is the same thing pci_stop_behind_bridge() did. Signed-off-by: Bjorn Helgaas Acked-by: Yinghai Lu

PCI: replace struct pci_bus secondary/subordinate with busn_res

2012-06-13T21:42:22+00:00

Replace the struct pci_bus secondary/subordinate members with the struct resource busn_res. Later we'll build a resource tree of these bus numbers. [bhelgaas: changelog] Signed-off-by: Yinghai Lu Signed-off-by: Bjorn Helgaas

PCI: Rename pci_remove_behind_bridge to pci_stop_and_remove_behind_bridge

2012-02-27T20:14:55+00:00

The old pci_remove_behind_bridge actually do stop and remove. Make the name reflect that to reduce confusion. Suggested-by: Jesse Barnes Signed-off-by: Yinghai Lu Signed-off-by: Jesse Barnes

pcmcia: replace struct irq with uint pcmcia_irq in struct pcmcia_socket

2010-05-10T08:23:12+00:00

As we don't need the "Config" counter any more, we can simplify struct pcmcia_socket. Signed-off-by: Dominik Brodowski

pcmcia: CodingStyle fixes

2010-03-03T07:32:15+00:00

Fix most of the remaining CodingStyle issues in drivers/pcmcia , which related to wrong indent -- PCMCIA historically used 4 spaces. Also, remove a custom min() implementation with the generic one. Signed-off-by: Dominik Brodowski

pcmcia: CardBus doesn't need CIS access

2010-01-17T17:30:13+00:00

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. CC: Jesse Barnes CC: Linus Torvalds Tested-by: Wolfram Sang Signed-off-by: Dominik Brodowski

PCI/cardbus: Add a fixup hook and fix powerpc

2009-12-17T02:55:51+00:00

The cardbus code creates PCI devices without ever going through the necessary fixup bits and pieces that normal PCI devices go through. There's in fact a commented out call to pcibios_fixup_bus() in there, it's commented because ... it doesn't work. I could make pcibios_fixup_bus() do the right thing on powerpc easily but I felt it cleaner instead to provide a specific hook pci_fixup_cardbus for which a weak empty implementation is provided by the PCI core. This fixes cardbus on powerbooks and probably all other PowerPC platforms which was broken completely for ever on some platforms and since 2.6.31 on others such as PowerBooks when we made the DMA ops mandatory (since those are setup by the fixups).
