mfd: dbx500/abx500: root out hardcoded IRQ assignments
The DBx500 and ABx500 should be getting their IRQs from the
device tree and nowhere else. Get rid of all the static assignments
everywhere, delete it from the driver, platform data and the
board files in one swift strike.
Lots of cross-dependencies in the MFD drivers for PRCMU and
AB8500 makes it necessary to strike everywhere at once to
eradicate IRQs passed as resources and platform data to the left
and right around the platform.

ARM: ux500: Pass remnant platform data though to DMA40 driver
Ironically, in order to remove lots of the auxdata assignments, we have
to add just one more. A lot of them require DMA information to be passed
into clients for DMA channel allocation, but we now have this capability
in Device Tree. However, the DMA40 driver still relies on a reverse table
look-up to obtain DMA addresses. Until all of the clients are converted,
over to the new API, we're stuck with this.
Also, now the DMA40 has been DT:ed, there's no requirement to register
it using traditional methods, so let's remove it.

dmaengine: ste_dma40: Amalgamate DMA source and destination channel numbers
Devices which utilise DMA use the same device numbers for transmitting
and receiving. In this patch we encode the source and destination
information into one single attribute. We can subsequently exploit the
direction attribute to see which of the transfer directions are being
described. This also lessens the burden on platform data.

We cannot use a global variable stored in <mach/hardware.h> to

Currently the patch is kept minimal so as not to interfere with

point the defines using (prcmu_base + 0xnnn) need to be replaced
by pure offset defined for (0xnnn) and the base inlined with the

ARM: ux500: Enable the clock controlling Ethernet on Snowball
This fixes a regression introduced by common clk enablement.
On some u8500 based boards, the FMSC clock which is usually used
for flash, is wired up to the SMSC911x Ethernet driver. However,
the SMSC911x doesn't have common clk support yet, rendering it
unusable. Prior to the introduction of common clk the FMSC clock
was default on; however, common clk disables all clocks by default
and insists drivers take responsibility to enable theirs.
This fix enables the FMSC clock on Snowball, subsequently turning
on the SMSC911x Ethernet chip. It will be removed when the driver
is compatible with common clk.

mfd: db8500-prcmu: update resource passing
When trying to get rid of the cross-includes of <mach/id.h>
from different drivers, so we can localize ASIC/CPU detection
to the mach-ux500 folder, we run into the way the PRCMU
handles base addresses and firmware detection.
This patch updates the firmware version detection to pass
the required information as platform data instead of
relying on cpu_is_* macros.
Now the PRCMU base address, the secondary TCDM area, the
TCPM area and the IRQ are passed as resources instead of
being grabbed from <mach/*> files. Incidentally this also
removes part of the reliance on <mach/irqs.h>.
Further it updates the firmware version detection, since the
location of the firmware ID bytes in the designated memory
are is now passed from the platform data instead. There is
no reason not to include the nice split-off of a struct to
hold the firmware information and a separate function to
populate it.
The patch actually rids the need to use the external
db8500_prcmu_early_init call at all, but I'm keepin back
that removal as I don't want the patch to be too big.

ARM: ux500: List DT compatibility using platform names rather than by board
So far, each ST-Ericsson board supported by Device Tree has been similar
enough to run though a single DT_MACHINE_INIT call. On the back of that
it has been suggested that we should reduce the number of compatible
strings in our dt_compat structure. After subsequent discussion with Arnd
Bergmann the conclusion was to list entries by platform as opposed to by
board.
The other suggestion was to use a single string which would cover all
supported platforms, but any wildcard entries would include unsupported
chipsets, such as the u5500 and potential new chips which no not yet have
DT functionality. Hence, the best solution which encompasses all supported
platforms, but no unsupported ones was to list the currently enabled four
chipsets; u8500, u8540, u9500 and u9540 instead.

ARM: pmu: remove arm_pmu_type enumeration
The arm_pmu_type enumeration was initially introduced to identify
different PMU types in the system, the usual one being that on the CPU
(ARM_PMU_DEVICE_CPU). With the removal of the PMU reservation code and
the introduction of devicetree bindings for the CPU PMU, the enumeration
is no longer required.
This patch removes the enumeration and updates the various CPU PMU
platform devices so that they no longer pass an .id field referring
to identify the PMU type.

ARM: ux500: Register the AB8500 from DB8500 MFD
As the AB8500 is a subordinate MFD device to the DB8500-PRCMU,
for consistency and a better 1:1 depiction of how the hardware
is laid out, it is a good idea to register it in the same way
as we do for the other MFD child devices. In order for us to do
this successfully we have to pass AB8500's platform data when
registering the DB8500-PRCMU from platform code.
Also solves this issue:

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.
