2016-03-29pcmcia: db1xxx_ss: fix last irq_to_gpio userManuel Lauss1-2/+9
remove the usage of removed irq_to_gpio() function. On pre-DB1200 boards, pass the actual carddetect GPIO number instead of the IRQ, because we need the gpio to actually test card status (inserted or not) and can get the irq number with gpio_to_irq() instead. Tested on DB1300 and DB1500, this patch fixes PCMCIA on the DB1500, which used irq_to_gpio().

2016-02-16gpio: Include linux/gpio.h instead of asm/gpio.hBjorn Helgaas2-2/+1
Most arches have an asm/gpio.h that merely includes linux/gpio.h. The others select ARCH_HAVE_CUSTOM_GPIO_H, and when that's selected, linux/gpio.h includes asm/gpio.h. Therefore, code should include linux/gpio.h instead of including asm/gpio.h directly. Remove includes of asm/gpio.h, adding an include of linux/gpio.h when necessary. This is a follow-on to 7563bbf89d06 ("gpiolib/arches: Centralise bolierplate asm/gpio.h").

2015-06-16pcmcia: do not break rsrc_nonstatic when handling anonymous cardsDominik Brodowski2-21/+27
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>

There are some resource leaks in yenta_probe() and _close(). I fixed the following issues with some code cleanups. Thanks to Dominik's suggestions. On the error path in yenta_probe(): - a requested irq is not released - yenta_free_resources() and pci_set_drvdata(dev, NULL) are not called In yenta_close(): - kfree(sock) is not called - sock->base is always set to non-NULL when yenta_close() is called, therefore the check in yenta_close() is not necessary.

Disable write buffering on the Toshiba ToPIC95 if it is enabled by somebody (it is not supposed to be a power-on default according to the datasheet). On the ToPIC95, practically no 32-bit Cardbus card will work under heavy load without locking up the whole system if this is left enabled. I tried about a dozen. It does not affect 16-bit cards.

2015-01-13pcmcia: add missing include for new pci resource handlerArnd Bergmann1-0/+1
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.

2015-01-12pcmcia: add a new resource manager for non ISA systemsAlan Cox3-3/+182
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).

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 Cox2-1/+4
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. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
