b2596c6828 ARM: pxa: hx4700: Add Synaptics NavPoint touchpad
This patch adds the Synaptics NavPoint touchpad to the hx4700 platform:
1. Change GPIO23_SSP1_SCLK value in hx4700_pin_config[] from an output
to an input, since the NavPoint is connected to SSP in SPI slave mode.
2. Add GPIO102_GPIO (NavPoint power) to hx4700_pin_config[].
3. Add navpoint platform_device to devices[].

b298322b75 ARM: pxa: use ioremap to access CPLD
The pcm990 baseboard for the pcm027 module used to setup a static
mapping for accessing the CPLD. It became illegal to call iotable_init
that late. The pcm027 support is broken since then. This patch
switches the cpld support to ioremap and removes all references to
previous static mappings.

Pins that have MFP_LPM_KEEP_OUTPUT set and are configured for output
must retain the output state in low power mode.
Currently, the pin direction configuration is overrided with values
in gpdr_lpm[] array and do not obey the MFP_LPM_KEEP_OUTPUT setting.

Fix the above bug and add some documentation to clarify the
MFP_LPM_KEEP_OUTPUT setting purpose.

1ac02d7958 ARM: fix __io macro for PCMCIA
With commit c334bc1 (ARM: make mach/io.h include optional), PCMCIA was
broken. PCMCIA depends on __io() returning a valid i/o address, and most
ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This
needs a better fix with a fixed i/o address mapping, but for now we just
restore things to the previous behavior.

This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled,
but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff,
so it doesn't need an io.h.

Rob Herring has done a sweeping change cleaning up all of the mach/io.h includes,
 moving some of the oft-repeated macros to a common location and removing a bunch of
 boiler plate. This is another step closer to a common zImage for multiple platforms.

1bfecd9358 ARM: board specific updates
These changes are all specific to one board only. We're trying to keep
 the number of board files low, but generally board level updates are
 ok on platforms that are working on moving towards DT based probing,
 which will eventually lead to removing them.
 
 The board-ams-delta.c board file gets a conflict between the removal of
 ams_delta_config and the addition of a lot of other data. The Kconfig
 file has two changes in the same line, and in exynos, the power domain
 cleanup conflicts with the addition of the image sensor device.

The only users of ARCH_HAS_DMA_SET_COHERENT_MASK are 2 ARM platforms:
ixp4xx and pxa cm_x2xx. We've been getting lucky that the define is
implicitly included before dma-mapping.h, but the removal of io.h broke
things (c334bc1 ARM: make mach/io.h include optional). Since memory.h
is the correct place, but no longer exists, convert the define to a
kconfig entry.

a9bb5a4bf9 PCMCIA: pxa: convert PXA socket drivers to use new irq/gpio management
Convert all the PXA platform socket drivers to use the new irq/gpio
management provided by soc_common.  This relieves these drivers from
having to do anything with these GPIOs other than provide the numbers
to soc_common.

Remove the now empty arch_reset() from all the mach/system.h includes,
and remove its callsite.  Remove arm_machine_restart() as this function
no longer does anything useful.

For samsung platforms, remove the include of mach/system-reset.h and
plat/system-reset.h from their respective mach/system.h headers as these
just define their arch_reset functions.  As a result, the s3c2410 and
plat-samsung system-reset.h files are no longer referenced, so remove
these files entirely.

abeb24ae4d ARM: Make global handler and CONFIG_MULTI_IRQ_HANDLER mutually exclusive
Even when CONFIG_MULTI_IRQ_HANDLER is selected, the core code
requires the arch_irq_handler_default macro to be defined as
a fallback.

It turns out nobody is using that particular feature as both PXA
and shmobile have all their machine descriptors populated with
the interrupt handler, leaving unused code (or empty macros) in
their entry-macro.S file just to be able to compile entry-armv.S.

Make CONFIG_MULTI_IRQ_HANDLER exclusive wrt arch_irq_handler_default,
which allows to remove one test from the hot path. Also cleanup both
PXA and shmobile entry-macro.S.

GPIO0 and GPIO1 are linked to unique interrupt line in PXA series,
others are linked to another interrupt line. All GPIO are linked to one
interrupt line in MMP series.

Since gpio driver is shared between PXA series and MMP series, define
GPIO0 and GPIO1 as chained interrupt chip. So we can move out gpio code
from irq.c to gpio-pxa.c.

639da5ee37 ARM: add an extra temp register to the low level debugging addruart macro
Some platforms (like OMAP not to name it) are doing rather complicated
hacks just to determine the base UART address to use.  Let's give their
addruart macro some slack by providing an extra work register which will
allow for much needed cleanups.

This is basically a no-op as this commit is only adding the extra argument
to the macro but no one is using it yet.
