The i.MX31 PDK consists of several boards, one of them is a debug
board containing a CPLD which controls some debug leds, switch
buttons, an interrupt chip and an Ethernet controller.
This patch adds support for detecting if the PDK board is present
(during boot) and adds the interrupt chip to the kernel.

Since iomux code is not directly related to gpio on mx31, the calls
to gpio_request are removed from iomux.c file.
These calls have to be done in platform initialization files. The
name of the singe pin call for iomux is also changed to
mxc_iomux_alloc_pin.

* Kconfig enables now HAVE_PWM (this enables in turn the selection of
CONFIG_BACKLIGHT_PWM)
* changes CONFIG_ARCH_MXyy to CONFIG_MACH_MXyy
* fix some register names to match those of the reference manual
* write a stub code so that the PWM can be used to program the
LCD backlight
* convert from #ifdef CONFIG_ARCH_MXxx to cpu_is_mxXX()
* remove unneeded defines and fix 80-column "violations" of checkpatch.pl

MXC GPIO controller does not support generation of interrupts on both
edges. Emulate this mode in software by reconfiguring the irq trigger
polarity on each interrupt. This follows an example of
drivers/mfd/asic3.c.

Currently we depend on hardcoded base addresses for the interrupt
controller. This prevents us from compiling in more than one i.MX
architecture at a time. This patch changes the base address to a
runtime calculated one.

Before this patch I got the following line in my dmesg:
[ 0.000000] BUG: mapping for 0xd4000000 at 0xeb000000 overlaps vmalloc space
VMALLOC_END is 0xf4000000 and there are the following other mappings
defined for mx27ads:
(0xa0500000,+0x00001000) maps to 0xffff0000
(0x10000000,+0x00100000) maps to 0xf4000000
(0x80000000,+0x00100000) maps to 0xf4100000
(0xd8000000,+0x00100000) maps to 0xf4200000
So map PBC to 0xf4300000.

that isn't an ARCH-wide setting anyway. If a device has two

OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not. There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().
This patch fixes things to pass this string to arch_reset(). This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.

This patch adds clock support for i.MX35 SoCs. We do not support setting
of clock rates yet, but most interesting clock rates should be reported.
I couldn't test all clock rates and the datasheet contains some obvious
bugs, so expect some bugs in this code.

We had hardcoded cpu_is_ macros for mxc architectures till now. As we
want to run the same kernel on i.MX31 and i.MX35 this patch adds cpu_is_
macros which expand to 0 or 1 if only one architecture is compiled in and
only check for the cpu type if more than one architecture is compiled
in.

This enables our mx31moboard to be used on the different baseboards that
we are developping according to the application needs. There are not
many differences between the boards for now, but when other peripherals
are available for mx31 the differences are going to grow.
