3169663ac5 ARM: sa11x0/pxa: convert OS timer registers to IOMEM
Make the OS timer registers have IOMEM like properities so they can
be passed to readl_relaxed/writel_relaxed() et.al. rather than being
straight volatile dereferences.  Add linux/io.h includes where
required.

linux/io.h includes added to arch/arm/mach-sa1100/cpu-sa1100.c,
 arch/arm/mach-sa1100/jornada720_ssp.c, arch/arm/mach-sa1100/leds-lart.c
 drivers/input/touchscreen/jornada720_ts.c, drivers/pcmcia/sa1100_shannon.c
from Arnd.

This fixes these warnings:

arch/arm/mach-sa1100/time.c: In function 'sa1100_timer_init':
arch/arm/mach-sa1100/time.c:104: warning: passing argument 1 of 'clocksource_mmio_init' discards qualifiers from pointer target type
arch/arm/mach-pxa/time.c: In function 'pxa_timer_init':
arch/arm/mach-pxa/time.c:126: warning: passing argument 1 of 'clocksource_mmio_init' discards qualifiers from pointer target type

f408c985ce GPIO: sa1100: implement proper gpiolib gpio_to_irq conversion
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.

9d08d5d77a ARM: 7050/1: mach-sa1100: delete irq_to_gpio() function
This function is not used in the assabet build, and on the whole the
call is hard to consolidate so get rid of it from this machine.

8f3c4537bb ARM: gpio: make trivial GPIOLIB implementation the default
Rather than marking the mach/gpio.h header files which want to use the
trivial GPIOLIB implementation, mark those which do not want to use it
instead.  This means that by default, you get the trivial implementation
and only have to do something extra if you need to.  This should
encourage the use of the trivial default implementation.

As an additional bonus, several gpio.h header files become empty.

cc64717279 SA1100: make gpio_to_irq and reverse a macro
The function can't be used for static initialisations so
convert them to macros.

a09e64fbc0 [ARM] Move include/asm-arm/arch-* to arch/arm/*/include/mach
This just leaves include/asm-arm/plat-* to deal with.
