This driver does an unconditional read of io space during module init which
causes a bad dereference on ARM. It looks to me like this is an x86 only
drivers, so restrict it to only compile on x86.

The __iomem annotation is to be used together with pointers used
in iowrite32() but not for pointers returned by kzalloc().
For more details see [1] and [2].
This patch will remove the following sparse warning (i.e. when
copiling with "make C=1"):
* warning: incorrect type in assignment (different address spaces)

The existing gpio_to_irq() implementation on sa1100 only translates
validly for internal GPIOs. Since this sub-arch enables GPIOLIB
support, this results in buggy translations for non-internal GPIOs.
Get rid of the private gpio_to_irq() implementation, replacing it
with the .to_irq method in the sa1100 gpio chip instead.

Drivers should not have a dependency on NR_IRQS. Doing so may break with
SPARSE_IRQ enabled. As there are no in kernel users of the pl061 which
have multiple instances with their interrupts combined to a single parent
interrupt, remove this functionality. If this capability is needed later,
it could be supported more cleanly by just using a devicetree property.

As gpio chips get registered, a device tree node which represents the
gpio chip is searched and attached to it. A translate function is also
provided to convert the gpio specifier into actual platform settings
for pin function selection, pull up/down and driver strength settings.

[kgene.kim@samsung.com: fixed build error]

The sysdev.h file should not be needed by any in-kernel code, so remove
the .h file from these random files that seem to still want to include
it.
The sysdev code will be going away soon, so this include needs to be
removed no matter what.

Add a 5121-custom reject if an input-only pin is requested to be output
(see 18.3.1.1 in the refman). Also, rewrite mach-specific quirk setup to
consume less lines which scales better.

GPIO's irq action's dev_id is set to the first struct ioh_gpio chip,
so when loop checking the 8 chips, the "chip" should be changed
according.

A large chunk of qe_pin_request() is unnecessarily cut-and-paste
directly from of_get_named_gpio_flags(). This patch cuts out the
duplicate code and replaces it with a call to of_get_gpio().

I screwed up by compiling that driver for the machine rather

Commit af0c25c487 ("staging: remove obsoleted CS5535/CS5536 GPIO
driver") dropped CS5535_GPIO. So this last reference to CS5535_GPIO has
been an (inconsequential) nop since v3.1. Drop it too.
