9b1489e989 Merge branch 'mxc-master' of git://git.pengutronix.de/git/imx/linux-2.6 into imx/master
Removed selection of COMMON_CLKDEV by CONFIG_ARCH_MX5.  This is handled
in 03e09cd890.

arch/arm/plat-mxc/iomux-mx1-mx2.c was moved to
arch/arm/plat-mxc/iomux-v1.c in 5e2e95f520
and got bug fixed in 5c17ef878f.  The bug
in arch/arm/plat-mxc/iomux-v1.c isn't present any more since
bac3fcfad5, so
arch/arm/plat-mxc/iomux-mx1-mx2.c is simply deleted.

Conflicts:
	arch/arm/plat-mxc/Kconfig
	arch/arm/plat-mxc/Makefile
	arch/arm/plat-mxc/iomux-mx1-mx2.c

08268b78d6 mx25: move ARCH_MXC_IOMUX_V3 to the ARCH level
ARCH_MXC_IOMUX_V3 is not specific to the i.MX25 PDK platform. Thus,
ARCH_MXC_IOMUX_V3 should be selected by ARCH_MX25.

bac3fcfad5 arm/imx/iomux-v1: check for invalid modes in mxc_gpio_mode
mxc_gpio_mode checks for invalid pins and so it returns zero for
success, -EINVAL for invalid pins.

While at it, remove definitions of GPIO_PORT_MAX removed as they are
unused now.

111588f830 arm/imx/iomux-v1: rename header file
Addionally make iomux-mx*.h headers stand-alone and similar to iomux-v3
platform files should include their platform iomux header from now on.
For now iomux.h simply includes all iomux-v1 platform headers and so
provides compatibility until all files are converted.

3d40f7fef4 arm/imx/gpio: GPIO_INT_{HIGH,LOW}_LEV are not necessarily constant
GPIO_INT_LOW_LEV is defined as

	(cpu_is_mx1_mx2() ? 0x3 : 0x0)

so depending on compiler optimisation and enabled SoCs this doesn't
qualify as a constant expression as needed by a switch statement.
Ditto for GPIO_INT_HIGH_LEV.

The old names are defined only if the cpp symbol

This was done earlier for mx2 and mx3, too.

USBD_INT0 is for now defined unconditionally to prevent breaking
drivers/usb/gadget/imx_udc.

While at it use IMX_IO_ADDRESS to define MX1_IO_ADDRESS which
adds a cast to the IO_ADDRESS macro fixing many warnings like
