This adds the camera device based on Guennadi's soc_camera architecture
for the mx31.
The proposed init by Guennadi was removed and must be implemented in the
board init file as it contains a lot of board specific info (memory
size, clock speed).

In order to use the gpiolib, we now have to call gpio_request in

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.

This support both sdhc1 and sdhc2 with WP and CD for the marxbot and
devboard mx31moboard baseboards.
sdhc2 is present on both, but is not directly included in the
mx31moboard file because a third baseboard (not supported yet) without
sdhc2 is planned.
Changes since v1: removed pin initialization from init/exit function and
taken different comments into account

This allows us to have more mapping functions for more than one

It is no longer present in newer cores. Unfortunately Freescale decided
to put the bit which decides between automotive clock path and consumer
clock path in the automotive clock path direction. With current code we
cannot detect the core revision, so just remove automotive path completely.

This iomux is called iomux-v3 in the tree because it is the third known

on the MX51 and probably others.

With the i.MX31 transition to clkdev clock names have changed, but mistakenly
the "mx3-camera.0" has been registered with a non-NULL connection ID, which is
not necessary, since this is the only clock, used by the capture interface
driver. Fix the clock definition and the driver to use NULL as a connection ID.

The i.MX35 basically features the same peripherals as the i.MX31 with
some differences:
- The i.MX35 has a FEC ethernet controller
- The NAND controller base addresses are different
- The i.MX35 has only 3 UARTs

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.

The i.MX31ADS supports pluggable PMU modules, including the WM835x based
Wolfson Microelectronics 1133-EV1. These boards provide power, audio,
RTC and watchdiog services to the system. This patch adds initial support
for those boards in I2C mode.
Currently support is limited by the available support for the features
of the i.MX31 in the mainline kernel. Some further work will be needed
once other PMU modules are supported and once there is SPI support.
Many of the regulator constraints will be sharable with other PMU
boards.
