This patch reverts "ARM: mach-shmobile: sh7372 SDHI vector merge" and
supplies 3 IRQ resources for each SDHI block.
Some blocks have a 4th IRQ, but this is used for DRM feathres
that I do not have access tot he documentation for and are almost
certainly tainted by licensing issues. So the 4th IRQ is not
hooked-up even if it exists.

Update the sh7372 clock code to set the RT side
set of MSTP bits to a fixed disabled state.
The sh7372 SoC contains two sets of MSTP bits,
one for the ARM (SYS) side, and one for the
SH4AL-DSP (RT) side. The actual clock associated
with the MSTP bit will only be stopped when both
sides have set the MSTP bit to disabled mode.
Some MSTP bits are enabled by default after
hardware reset, so this patch adjusts the code
to disable all MSTP bits associated with the RT
side to allow the SYS side to have full control.

If a dtb is passed to the kernel then the kernel needs to iterate
through compiled-in mdescs looking for one that matches and move the
dtb data to a safe location before it gets accidentally overwritten by
the kernel.
This patch creates a new function, setup_machine_fdt() which is
analogous to the setup_machine_atags() created in the previous patch.
It does all the early setup needed to use a device tree machine
description.
v5: - Print warning with neither dtb nor atags are passed to the kernel
- Fix bug in setting of __machine_arch_type to the selected machine,
not just the last machine in the list.
Reported-by: Tixy <tixy@yxit.co.uk>
- Copy command line directly into boot_command_line instead of cmd_line
v4: - Dump some output when a matching machine_desc cannot be found
v3: - Added processing of reserved list.
- Backed out the v2 change that copied instead of reserved the
dtb. dtb is reserved again and the real problem was fixed by
using alloc_bootmem_align() for early allocation of RAM for
unflattening the tree.
- Moved cmd_line and initrd changes to earlier patch to make series
bisectable.
v2: Changed to save the dtb by copying into an allocated buffer.
- Since the dtb will very likely be passed in the first 16k of ram
where the interrupt vectors live, memblock_reserve() is
insufficient to protect the dtb data.

When initialising a PMU, there is a check to protect against races with
other CPUs filling all of the available event slots. Since armpmu_add
checks that an event can be scheduled, we do not need to do this at

assumes that atomic_inc_not_zero will unconditionally increment
active_counts and then tries to decrement it again on failure.

The current implementation defines an internal structure and a
C-states array. Using those structures is redundant to the
structs used by the cpuidle framework.
This patch provides a clean-up of the internal struct, removes the
internal C-states array, stores the data using the existing cpuidle
per C-state struct and registers the mach specific data to cpuidle
C-state driver_data (accessed using cpuidle_[gs]et_statedata).
Also removes unused macros, fields and code and compacts the repeating
code using an inline helper function.
The result is more compact and more readable code as well as
reduced data RAM usage.
Also retain C1 as the only always valid C-state and system safe state.

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.)

The symbols in this choice should only be used to select between the
available machines that can be built into a single kernel. As these sets
(will) differ e.g. depending on ARM_PATCH_PHYS_VIRT and AUTO_ZRELADDR
letting them select other symbols makes the logic more complex and needs
to duplicate some things. So let the machines select the corresponding
symbols (indirectly via SOC_XYZ).

The platform id is used to determine the spi bus number, so it should
better be different to the ids used for imx51-ecspi. Otherwise it's not
possible to use both devices "imx51-cspi.0" and "imx51-ecspi.0".
Alternative approaches are to use dynamic bus numbering as offered by
the spi framework or let the machine code set the bus number. The
downside of both possibilities is that the bus number isn't fixed for
the same busses on different machines using i.MX51.

... 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
