890d84fac0 ARM: ux500: Allow PRCMU regulator to be probed during a DT enabled boot
This patch adds the correct compatible string for use during Device Tree
population. Without it the DB8500 PRCMU regulators would be processed
when DT is enabled.

fd6948bb2a ARM: ux500: Only initialise STE's UIBs on boards which support them
ST-Ericsson uses User Interface Boards to extend functionality of
some of their development boards. However, these aren't compatible
with all the supported boards found in Mainline (Snowball for
instance). This patch ensures that the UIBs are only probed on
boards which can actually support them. This in turn saves lots of
unnecessary error messages normally found in Snowball's boot log.

48a4ea626d ARM: ux500: Disable platform setup of the ab8500 when DT is enabled
The final piece of the ab8500 puzzle. Here we prevent any of the ab8500-*
drivers from being registered from platform code when Device Tree is
enabled, as we expect DT do probe each of these individually. We also
provide the relevant compatible strings, so that DT knows which nodes
it needs to pay attention to during population.

e6fada59d4 ARM: ux500: Re-enable SMSC911x platform code registration during non-DT boots
The patch to disable SMSC911x registration was applied twice in the upstream
kernel by mistake. Git interpreted this as 'take the same entry from a
similar struct' which was close by. This was the wrong thing to do. This patch
rectifies this error and re-enables SMSC911x registration when Device Tree is
not enabled.

dee42ebe45 ARM: ux500: Remove DB8500 PRCMU platform registration when DT is enabled
Now the DB8500 has Device Tree support it will be probed when the DT
is parsed, rendering the requirement for platform registration void.

ada46cda50 ARM: ux500: Disable SMSC911x platform code registration when DT is enabled
Now the SCMC911x is correctly enabled in Device Tree, there is no need
to continue registering it from platform code. In fact, if we continue
doing so, the system will throw an error on boot.

f65c1982fa ARM: ux500: New DT:ed u8500_init_devices for one-by-one device enablement
During Device Tree enablement it is necessary to remove
<hw_component>_add_<device> calls one at at time, as and when particular
devices are DT enabled. This patch provides a temporary solution. Once
the new *of_init_devices function has been fully unpopulated it will be
removed again.

f465d145d7 arm-soc: sweeping late_initcall cleanup
This is a patch series from Shawn Guo that moves from individual
 late_initcalls() to using a member in the machine structure to invoke
 a platform's late initcalls.
 
 This cleanup is a step in the move towards multiplatform kernels since
 it would reduce the need to check for compatible platforms in each and
 every initcall.

b324c67d48 arm-soc: device tree conversions, part 1
The spear3xx, lpc32xx, shmobile and mmp platforms are joining the game of
 booting using device trees, which is a great step forward for them. at91
 and spear have pretty much completed this process with a huge amount of
 work being put into at91. The other platforms are continuing the process.
 
 We finally start to see the payback on this investment, as new machines
 are getting supported purely by adding a .dts source file that can be
 completely independent of the kernel source.

9bc747bea5 arm-soc: First batch of cleanups
These cleanups are basically all over the place. The idea is to collect
 changes with minimal impact but large number of changes so we can avoid
 them from distracting in the diffstat in the other series.
 
 A significant number of lines get removed here, in particular because
 the ixp2000 and ixp23xx platforms get removed. These have never been
 extremely popular and have fallen into disuse over time with no active
 maintainer taking care of them. The u5500 soc never made it into a
 product, so we are removing it from the ux500 platform.
 
 Many good cleanups also went into the at91 and omap platforms, as has
 been the case for a number of releases.

After allocating ab8500 memory, it immediately calls into

e98ea774c8 pinctrl/nomadik: basic Nomadik pinctrl interface
This adds a scratch pin control interface to the Nomadik pinctrl
driver, and defines the pins and groups in the DB8500 ASIC. We
define GPIO ranges to cover the pins exposed. The DB8500 has
more pins than this but we restrict the driver to the pins that
can be controlled from the combined GPIO and pin control hardware
to begin with.

ChangeLog v1->v2:
- Base on the latest pinctrl development from
  pinctrl-mergebase-20120418 so we can get rid of legacy
  group count mechanism. Also drop the range checks for group
  index, this is handled by the core now.

This patch adds the cpuidle driver for the ux500 SoC.
The boards saves 12mA with these states. It is based on the latest
cpuidle consolidation from Robert Lee.

The cpu can go to retention only if the other core is in WFI.

If the other cpu is in WFI and we decoupled the gic from the cores,
then we have the guarantee, it won't be wake up.

It is up to the prcmu firmware to recouple the gic automatically
after the power state mode is selected.

In dbx500 based devices the PRCMU Timer 4 is used as a clocksource
and sched_clock. Here we fetch all necessary addressing information
required for correct PRCMU initialisation from the Device Tree
instead of using hard-coded values.

f58546a17c ARM: ux500: Disable SMSC911x platform code registration when DT is enabled
Now the SCMC911x is correctly enabled in Device Tree, there is no need
to continue registering it from platform code. In fact, if we continue
doing so, the system will throw an error on boot.

08d0502631 ARM: ux500: Fork cpu-db8500 platform_devs for sequential DT enablement
To aid in sequential one-by-one Device Tree enablement, we split
cpu-db8500's platform_devs structure into normal platform boot, where
we leave all devices to be added in tact and a DT version where we
will remove the devices as they are DT enabled.

4809f90aad ARM: ux500: Do not attempt to register non-existent i2c devices on Snowball
This patch prevents i2c devices which are not present on the Snowball
low-cost development board from being registered. Devices such as;
tc3589x, bu1780 and lp5521 are present on other supported boards,
but are not located on Snowball.

29746f48d1 ARM: ux500: delete U5500 support
This platform has been obsoleted and was only available inside of
ST-Ericsson, no users of this code are left in the world. This
deletes the core U5500 support entirely in the same manner as the
obsoleted U8500 silicon was previously deleted.

The cpu_is_u5500() macros that can read out the CPU ID is left
until the next kernel cycle, this makes it possible to merge
deletion of dependent drivers without breakage.

This also has the upside of removing the mailbox driver which was
our only driver that was outside the drivers/* hiearchy, now the
machine directory only handles machines and nothing else.

bc71c0961c ARM: ux500: core U9540 support
This adds support for the U9540 variant of the U8500 series. This
is an application processor without internal modem. This is the
most basic part with ASIC ID, CPU-related fixes, IRQ list, register
ranges, timer, UART, and L2 cache setup. This is based on a patch
by Michel Jaouen which was rewritten to fit with the latest 3.3
kernel.

ChangeLog v1->v2: deleted the irqs-db9540.h file since we expect to
  migrate to using Device Tree for getting the IRQs to devices.
ChangeLog v2->v3: introduced a fixed virtual offset for the ROM
  as suggested by Arnd Bergmann.
