To configure pads during the initialisation a set of special constants
is used, e.g.
#define MX25_PAD_FEC_MDIO__FEC_MDIO IOMUX_PAD(0x3c4, 0x1cc, 0x10, 0, 0, PAD_CTL_HYS | PAD_CTL_PUS_22K_UP)
The problem is that no pull-up/down is getting activated unless both
PAD_CTL_PUE (pull-up enable) and PAD_CTL_PKE (pull/keeper module
enable) set. This is clearly stated in the i.MX25 datasheet and is
confirmed by the measurements on hardware. This leads to some rather
hard to understand bugs such as misdetecting an absent ethernet PHY (a
real bug i had), unstable data transfer etc. This might affect mx25,
mx35, mx50, mx51 and mx53 SoCs.
It's reasonable to expect that if the pullup value is specified, the
intention was to have it actually active, so we implicitly add the
needed bits.

The helper function mx27_setup_weimcs() references IOMEM() and
IMX_IO_P2V() but without required header mach/hardware.h included
in mx27.h. This will break the build of those mx27 file with no
direct inclusion of mach/hardware.h, or when indirect inclusion to
mach/hardware.h breaks.
For example, when the inclusion of mach/hardware.h gets removed from
mach/gpio.h, we will see the following compile error.

It is not good to have cpu_name and to_version encoded into sdma
firmware name as variables. For example, there are three TOs of
imx51 soc, the sdma script never changes since TO1, which means
all three TOs of imx51 uses TO1 version of sdma script. But we
have to prepare three identical firmwares, sdma-imx51-to1.bin
sdma-imx51-to2.bin and sdma-imx51-to3.bin, to have the kernel
capable of running on all three TOs.
The patch removes cpu_name and to_version from sdma platform data,

pass the TO version where it's relevant and skip it where only one
firmware exists.

When setting the IOMUX of multiple pins via mxc_gpio_setup_multiple_pins, gpio_request
is called and this prevents subsequent calls of gpio_request done by drivers to succeed.
Remove gpio_request call from mxc_gpio_setup_multiple_pins function.
As gpio_request is removed from mxc_gpio_setup_multiple_pins, there is no need to have
mxc_gpio_release_multiple_pins anymore, so remove this function.
Tested on a mx27_3ds board and after applying this patch it is possible to define all the
IOMUX setup in a static array

The patch makes necessary changes on gpio-mxc as below to turn it
into an upstanding gpio driver.
* Add a list to save all mx2 ports references, so that
mx2_gpio_irq_handler can walk through all interrupt status
registers
* Use readl/writel to replace mach-specific accessors
__raw_readl/__raw_writel
* Change mxc_gpio_init into mxc_gpio_probe function
* Move "struct mxc_gpio_port" into gpio-mxc.c, as it needs not to
be public at all, and also make some other cleanup on
plat-mxc/include/mach/gpio.h at the same time
And the patch then migrates mach-imx and mach-mx5 to the updated
driver by adding corresponding platform devices.

To be able to compile e.g. i.MX31 and i.MX51 in a single kernel image
the ioremap quirk needs a runtime check.
While touching this code make the comment more understandable by adding
a sentence from the commit log that introduced it
(eadefef ([ARM] MX3: Use ioremap wrapper to map SoC devices nonshared)).
As mach/io.h now uses cpu_is_ some header reshuffling in mach/hardware.h
was necessary. (mach/mx27.h and mach/mx31.h #include <linux/io.h> which
#includes <mach/io.h>. So mach/mxc.h which provides the cpu_is_ macros
needs to be included before mach/mx27.h and mach/mx31.h.)

... together with the related devices "mx3_camera" and "mx3_sdc_fb".
"mx3_camera" doesn't fit the scheme of the other devices that just are
allocated and registered in a single function because it needs additional
care to get some dmaable memory. So currently imx31_alloc_mx3_camera
duplicates most of imx_add_platform_device_dmamask, but I'm not sure it's
worth to split the latter to be able to reuse more code.
This gets rid of mach-mx3/devices.[ch] and so several files need to be
adapted not to #include devices.h anymore.

To be able to relocate the .bss section at run time independently from
the rest of the code, we must make sure that no GOTOFF relocations are
used with .bss symbols. This usually means that no global variables can
be marked static unless they're also const.
Let's remove the static qualifier from current offenders, or turn them
into const variables when possible. Next commit will ensure the build
fails if one of those is reintroduced due to otherwise enforced coding
standards for the kernel.
