d37a65bb46 gpio/mxc: Move Freescale MXC gpio driver to drivers/gpio
GPIO drivers are getting moved to drivers/gpio for cleanup and
consolidation.  This patch moves the plat-mxc driver.  Follow up
patches will clean it up and make it a fine upstanding gpio driver.

4bd597b633 ARM i.MX ehci: do ehci init in board specific functions
The mxc-ehci driver calls SoC specific phy initialization right after
calling board specific initialization. To offer greater flexibility for
boards to setup the phy and to get rid of some unnecessary flags in
platform data this patch lets the boards call the SoC specific phy
initialization and remove it from the driver.

Also, as we have two irq controllers for i.MX, irq.c is not

68a2f7301a ARM: imx: Add iram allocator functions
Add IRAM(Internal RAM) allocation functions using GENERIC_ALLOCATOR.
The allocation size is 4KB multiples to guarantee alignment. The
idea for these functions is for i.MX platforms to use them
to dynamically allocate IRAM usage.

66384eedd9 ARM: imx: Change the way nand devices are registered (generic part)
Instead of having a platform device defined in a devices.c and register
it in the machine file allocate it dynamically.  This reduces the size
of needed memory as the new function is discarded after init and only
the existing devices are created.

9f72ffedc8 ARM: imx: new Kconfig symbol and feature test macro for DMA on mx1 and mx2
This should be used instead of hard coding the corresponding platforms.
The feature test macro is needed to support different SOCs in a single
kernel image.  While at it rename dma-mx1-mx2 to dma-v1 as mx25 doesn't
use it and so the mx2 part is wrong and move the header to
arch/arm/mach-imx.

7e8d5cd93f USB: Add EHCI support for MX27 and MX31 based boards
The Freescale MX27 and MX31 SoCs have a EHCI controller onboard.
The controller is capable of USB on the go. This patch adds
a driver to support all three of them.

Users have to pass details about serial interface configuration in the
platform data.

The USB OTG core used here is the ARC core, so the driver should
be renamed and probably be merged with ehci-fsl.c eventually.

 - i.MX1 (tested)
 - i.MX2 (i.MX21 (to be tested), i.MX27 (tested))
 - i.MX3 (i.MX31 (tested))

TODO: It seems impossible to build a kernel for more than one CPU because the
timer do not follow the platform device rules. So it does only work if
timer 1 can be accessed on all CPUs at the same address.

c0db2ea4e3 MXC family: Add clock handling
Internal clock path handling for the mxc CPUs.

Changed against the original Freescale code (and against clocklib for example):
 - clock rate is always calculated whenever one ask for the current rate
   (means struct clk has no more a member called "rate"). So switching the PLL
   base frequency will propagate immediately to all other clocks that are
   depending on this frequency.
