* ARM: pxa/sa1100: move I/O space to PCI_IOBASEArnd Bergmann2022-05-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PXA and StrongARM1100 traditionally map their I/O space 1:1 into virtual memory, using a per-bus io_offset that matches the base address of the ioremap mapping. In order for PXA to work in a multiplatform config, this needs to change so I/O space starts at PCI_IOBASE (0xfee00000). Since the pcmcia soc_common support is shared with StrongARM1100, both have to change at the same time. The affected machines are: - Anything with a PCMCIA slot now uses pci_remap_iospace, which is made available to PCMCIA configurations as well, rather than just PCI. The first PCMCIA slot now starts at port number 0x10000. - The Zeus and Viper platforms have PC/104-style ISA buses, which have a static mapping for both I/O and memory space at 0xf1000000, which can no longer work. It does not appear to have any in-tree users, so moving it to port number 0 makes them behave like a traditional PC. - SA1100 does support ISA slots in theory, but all machines that originally enabled this appear to have been removed from the tree ages ago, and the I/O space is never mapped anywhere. - The Nanoengine machine has support for PCI slots, but looks like this never included I/O space, the resources only define the location for memory and config space. With this, the definitions of __io() and IO_SPACE_LIMIT can be simplified, as the only remaining cases are the generic PCI_IOBASE and the custom inb()/outb() macros on RiscPC. S3C24xx still has a custom inb()/outb() in this here, but this is already removed in another branch. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
* ARM: pxa: move pcmcia board data into mach-pxaArnd Bergmann2022-04-191-0/+125
| | | | | | | | | | | | | The drivers/pcmcia/pxa2xx_*.c are essentially part of the board files, but for historic reasons located in drivers/pcmcia. Move them into the same place as the actual board file to avoid lots of machine header inclusions.

* pcmcia: Replace zero-length array with flexible-arrayGustavo A. R. Silva2020-05-181-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

* pcmcia: remove long deprecated pcmcia_request_exclusive_irq() functionLinus Torvalds2018-08-181-10/+0
| | | | | | | | | | | | | | This function was created as a deprecated fallback case back in 2010 by commit eb14120f743d ("pcmcia: re-work pcmcia_request_irq()") for legacy cases.

Such cards are currently matched by orinoco_cs, which doesn't support WPA. They should be matched by hostap_cs. The first and the second product ID vary widely, so there are few users with some particular IDs. Of those, very few can submit a patch for hostap_cs or write a useful bugreport. It's still important to support their hardware properly. With PCMCIA_DEVICE_MANF_CARD_PROD_ID3, it should be possible to cover the remaining Intersil based designs that kept the numeric ID and the "version" of the reference design.

* pcmcia: clarify alloc_io_space, move it to resource handlersDominik Brodowski2010-05-101-2/+9
| | | | | | | | | | | Clean up the alloc_io_space() function by moving most of it to the actual resource_ops. This allows for a bit less re-directions. Future cleanups will follow, and will make up for the code duplication currently present between rsrc_iodyn and rsrc_nonstatic (which are hardly ever built at the same time anyway, therefore no increase in built size).

* pcmcia: dev_node removal (core)Dominik Brodowski2010-05-101-10/+0
| | | | | | | Remove the dev_node declaration. We now only pass the device name to the deprecated userspace tools. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: clean up cs.hDominik Brodowski2010-05-101-11/+0
| | | | | | With req_irq_t gone, we can get rid of some definitions. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: re-work pcmcia_request_irq()Dominik Brodowski2010-05-102-10/+8
| | | | | | | | | | | | | | | | | | | | | | | | Instead of the old pcmcia_request_irq() interface, drivers may now choose between: - calling request_irq/free_irq directly. Use the IRQ from *p_dev->irq. - use pcmcia_request_irq(p_dev, handler_t); the PCMCIA core will clean up automatically on calls to pcmcia_disable_device() or device ejection. - drivers still not capable of IRQF_SHARED (or not telling us so) may use the deprecated pcmcia_request_exclusive_irq() for the time being; they might receive a shared IRQ nonetheless.

* pcmcia: pass FORCED_PULSE parameter in pcmcia_request_configuration()Dominik Brodowski2010-05-101-0/+1
| | | | | | | As it's only used there it makes no sense relying on pcmcia_request_irq(). CC: alsa-devel@alsa-project.org Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: replace struct irq with uint pcmcia_irq in struct pcmcia_socketDominik Brodowski2010-05-101-4/+3
| | | | | | | As we don't need the "Config" counter any more, we can simplify struct pcmcia_socket. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: setup IRQ to be used by PCMCIA drivers at card insertDominik Brodowski2010-05-101-0/+3
| | | | | | | | | Setup the IRQ to be used by PCMCIA drivers already during the device registration stage, making use of a new function pcmcia_setup_irq(). This will allow us to get rid of quite a lot of indirection in the future. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: pcmcia_dev_present bugfixDominik Brodowski2010-04-212-9/+6
| | | | | | | | | pcmcia_dev_present is in and by itself buggy. Add a note specifying why it is broken, and replace the broken locking -- taking a mutex is a bad idea in IRQ context, from which this function is rarely called -- by an atomic_t.

* pcmcia: use dev_pm_ops for class pcmcia_socket_classDominik Brodowski2010-03-241-6/+0
| | | | | | | | | | | | Instead of requiring PCMCIA socket drivers to call various functions during their (bus) resume and suspend functions, register an own dev_pm_ops for this class. This fixes several suspend/resume bugs seen on db1xxx-ss, and probably on some other socket drivers, too. With regard to the asymmetry with only _noirq suspend, but split up resume, please see bug 14334 and commit 9905d1b411946fb3 . Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

| * pcmcia: use state machine for extended requeryDominik Brodowski2010-02-171-8/+3
| | | | | | | | | | | | | | | | | | The requery callback now also handles the addition of a second pseudo multifunction device. Avoids messing with dev_{g,s}et_drvdata(), and fixes any workqueue <-> skt_mutex deadlock.
