c2ad284412 arm: socfpga: Add new device tree source for actual socfpga HW
Up to this point, support for socfpga has only been on a virtual
platform. Now that actual hardware is available, we add the appropriate
device tree source files.

389d2111f4 ARM: msm: proc_comm_boot_wait should not be __init
msm_smd_probe is a driver probe function and may get
called after the __init time, so it must not call
any __init function, as the link-time warning reports.
Take away the __init annotation on proc_comm_boot_wait
to fix this.

Without this patch, building msm_defconfig results in:

WARNING: vmlinux.o(.text+0xb048): Section mismatch in reference from the function msm_smd_probe() to the function .init.text:proc_comm_boot_wait()
The function msm_smd_probe() references
the function __init proc_comm_boot_wait().
This is often because msm_smd_probe lacks a __init
annotation or the annotation of proc_comm_boot_wait is wrong.

a1fcb44e26 ARM: KVM: vgic: retire queued, disabled interrupts
An interrupt may have been disabled after being made pending on the
CPU interface (the classic case is a timer running while we're
rebooting the guest - the interrupt would kick as soon as the CPU
interface gets enabled, with deadly consequences).

The solution is to examine already active LRs, and check the
interrupt is still enabled. If not, just retire it.

- kvm_arm_get_running_vcpu(): returns the vcpu running at this point

- kvm_arm_get_running_vcpus(): returns the per-CPU variable holding

3401d54696 KVM: ARM: Introduce KVM_ARM_SET_DEVICE_ADDR ioctl
On ARM some bits are specific to the model being emulated for the guest and
user space needs a way to tell the kernel about those bits.  An example is mmio
device base addresses, where KVM must know the base address for a given device
to properly emulate mmio accesses within a certain address range or directly
map a device with virtualiation extensions into the guest address space.

We make this API ARM-specific as we haven't yet reached a consensus for a
generic API for all KVM architectures that will allow us to do something like
this.

7c4e9ced42 ARM: 7643/1: sched: correct update_sched_clock()
If we want load epoch_cyc and epoch_ns atomically,
we should update epoch_cyc_copy first of all.
This notify reader that updating is in progress.

If we update epoch_cyc first like as current implementation,
there is subtle error case.
Look at the below example.

<Initial Condition>
cyc = 9
ns = 900
cyc_copy = 9

== CASE 1 ==
<CPU A = reader>           <CPU B = updater>
                           write cyc = 10
read cyc = 10
read ns = 900
                           write ns = 1000
                           write cyc_copy = 10
read cyc_copy = 10

output = (10, 900)

== CASE 2 ==
<CPU A = reader>           <CPU B = updater>
read cyc = 9
                           write cyc = 10
                           write ns = 1000
read ns = 1000
read cyc_copy = 9
                           write cyc_copy = 10
output = (9, 1000)

If atomic read is ensured, output should be (9, 900) or (10, 1000).
But, output in example case are not.

So, change updating sequence in order to correct this problem.

After setup/enable, some IP blocks need some additional setting to
indicate the PRCM that they are inactive until they are configured.
Some examples on OMAP4 include the AESS and FSUSB IP blocks.

To fix this cleanly, this patch adds another optional function
pointer, enable_preprogram, to the IP block's hwmod data.  The function
that is pointed to is called by the hwmod code immediately after the
IP block is reset.

This version of the patch includes a patch description fix from Felipe.

a5120e89e7 ARM i.MX6: change mxs usbphy clock usage
This mxs usbphy is only needs to be on after system boots
up, and software never needs to control it anymore.
Meanwhile, usbphy's parent needs to be notified if usb
is suspend or not. So we design below mxs usbphy usage:

- usbphy1_gate and usbphy2_gate:
Their parents are dummy clock, we only needs to enable
it after system boots up.
- usbphy1 and usbphy2
Usage reserved bit for this clock, in that case, the refcount
will be updated, but without hardware changing.

c3f78f0763 ARM: ux500: use real AB8500 IRQ numbers instead of virtual ones
Any devices wishing to use the AB8500's GPIO IRQs were forced to
request virtual IRQs from the gpio-ab8500 driver. Now that
responsibility has been passed back to the AB8500 core driver,
devices can request real IRQ numbers instead. This patch removes
any traces of the old virtual IRQ conversion handlers, which will
force any drivers requesting IRQs to use real IRQS.

710a03e934 ARM: ux500: remove irq_base property from platform_data
AB8500 GPIO no longer handles its GPIO IRQs. Instead, the AB8500
core driver has taken back the responsibility. Prior to this
happening, the AB8500 GPIO driver provided a set of virtual IRQs
which were used as a pass-through. These virtual IRQs had a base
of MOP500_AB8500_VIR_GPIO_IRQ_BASE, which was passed though pdata.
We don't need to do this anymore, so we're pulling out the
property from the structure.

3992313488 Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM fixes from Russell King:
 "I was going to hold these off until v3.8 was out, and send them with a
  stable tag, but as everyone else is pushing much bigger fixes which
  Linus is accepting, let's save people from the hastle of having to
  patch v3.8 back into working or use a stable kernel.

  Looking at the diffstat, this really is high value for its size; this
  is miniscule compared to how the -rc6 to tip diffstat currently looks.

  So, four patches in this set:
   - Punit Agrawal reports that the kernel no longer boots on MPCore due
     to a new assumption made in the GIC code which isn't true of
     earlier GIC designs.  This is the biggest change in this set.
   - Punit's boot log also revealed a bunch of WARN_ON() dumps caused by
     the DT-ification of the GIC support without fixing up non-DT
     Realview - which now sees a greater number of interrupts than it
     did before.
   - A fix for the DMA coherent code from Marek which uses the wrong
     check for atomic allocations; this can result in spinlock lockups
     or other nasty effects.
   - A fix from Will, which will affect all Android based platforms if
     not applied (which use the 2G:2G VM split) - this causes
     particularly 'make' to misbehave unless this bug is fixed."

The association was present as part of the older data file

More details of the patch which fixed this up in the older
data file can be dound here..
http://www.spinics.net/lists/linux-omap/msg63076.html

Adding the .clkdm_name as part of the clk_hw_omap struct also

169c82a294 ARM: OMAP2: am33xx-hwmod: Fix "register offset NULL check" bug
am33xx_cm_wait_module_ready() checks if register offset is NULL.

int am33xx_cm_wait_module_ready(u16 inst, s16 cdoffs, u16 clkctrl_offs)
{
	int i = 0;

	if (!clkctrl_offs)
		return 0;

In case of AM33xx, CLKCTRL register offset for different clock domains
are not uniformly placed. An example of this would be the RTC clock
domain with CLKCTRL offset at 0x00.
In such cases the module ready check is skipped which leads to a data
abort during boot-up when RTC registers is accessed.

Remove this check here to avoid checking module readiness for modules
with clkctrl register offset at 0x00.

CONFIG_RTC_DRV_OMAP=y with v3.8-rc5.

The current HWMOD code expects the memory region with

flag.

CPGMAC0 hwmod entry specifies two memory regions and marks
both with the flag ADDR_TYPE_RT although only the 2nd region
has the SYSCONFIG register. This leads to the HWMOD code
accessing the wrong memory address for idle and standby

79d1f5c9ac ARM: 7641/1: memory: fix broken mmap by ensuring TASK_UNMAPPED_BASE is aligned
We have received multiple reports of mmap failures when running with a
2:2 vm split. These manifest as either -EINVAL with a non page-aligned
address (ending 0xaaa) or a SEGV, depending on the application. The
issue is commonly observed in children of make, which appears to use
bottom-up mmap (assumedly because it changes the stack rlimit).

Further investigation reveals that this regression was triggered by
394ef6403a ("mm: use vm_unmapped_area() on arm architecture"), whereby
TASK_UNMAPPED_BASE is no longer page-aligned for bottom-up mmap, causing
get_unmapped_area to choke on misaligned addressed.

This patch fixes the problem by defining TASK_UNMAPPED_BASE in terms of
TASK_SIZE and explicitly aligns the result to 16M, matching the other
end of the heap.

This happens because the DMA allocation code is not respecting atomic
allocations correctly.

GFP flags should not be tested for GFP_ATOMIC to determine if an
atomic allocation is being requested.  GFP_ATOMIC is not a flag but
a value.  The GFP bitmask flags are all prefixed with __GFP_.

The rest of the kernel tests for __GFP_WAIT not being set to indicate
an atomic allocation.  We need to do the same.

Some early GIC implementations return zero for the first distributor
CPU routing register.  This means we can't rely on that telling us
which CPU interface we're connected to.  We know that these platforms
implement PPIs for IRQs 29-31 - but we shouldn't assume that these
will always be populated.

So, instead, scan for a non-zero CPU routing register in the first
32 IRQs and use that as our CPU mask.

 Therefore, the LP5521/5523 platform code need to be fixed.

6048009818 ARM: OMAP4: PM: Warn users about usage of older bootloaders
OMAP4 CHIP level PM works only with newer bootloaders. The
dependency on the bootloader comes from the fact that the
kernel is missing reset and initialization code for some
devices.

While the right thing to do is to add reset and init code in
the kernel, for some co-processor IP blocks like DSP and IVA
it means downloading firmware into each one of them to execute
idle instructions.

While a feasible solution is worked upon on how such IP blocks
can be better handled in the kernel, in the interim, to avoid
any further frustration to users testing PM on OMAP4 and finding
it broken, warn them about the bootloader being a possible
cause.

814a18a5d0 ARM: OMAP AM3517/05: hwmod data: block WFI when EMAC active
According to Mark Greer, on OMAP AM3517/3505 chips, the EMAC is unable
to wake the ARM up from WFI:

    http://www.spinics.net/lists/arm-kernel/msg174734.html

Further troubleshooting was unable to narrow the problem down.  So we
don't have much choice other than to block WFI when the EMAC is active
with the HWMOD_BLOCK_WFI flag.

Based on Mark's original patch.  We're removing the omap_device-based
pm_lats code, so a different approach was needed.

This third version contains some corrections thanks to Mark's review.

Apparently, on some OMAPs, the MPU can't be allowed to enter WFI while
certain peripherals are active.  It's not clear why, and it's likely
that there is simply some other bug in the driver or integration code.
But since the likelihood that anyone will have the time to track these
problems down in the future seems quite small, we'll provide a
flag, HWMOD_BLOCK_WFI, to mark these issues in the hwmod data.

enters self-refresh.  So in the case where CORE stays active, just call
WFI directly from the mach-omap2/pm24xx.c code.  This removes some
unnecessary SRAM code.

This second version replaces the inline WFI with the corresponding
coprocessor register call, using tlbflush.h as an example.  This is
because the assembler doesn't recognize WFI as a valid ARMv6
instruction.

51482be9dc ARM: OMAP: USB: Add phy binding information
This is w.r.t the changes in PHY library to support adding and getting
multiple PHYs of the same type. In the new design, the
binding information between the PHY and the USB controller should be
specified in the platform specific initialization code. So it's been
done here for OMAP platforms.

e3e92a7be6 ARM: 7635/1: versatile: fix the PCI IRQ regression
The PCI IRQs were regressing due to two things:

- The PCI glue layer was using an hard-coded IRQ 27 offset.
  This caused the immediate regression.

- The SIC IRQ mask was inverted (i.e. a bit was indeed set to
  one for each valid IRQ on the SIC, but accidentally inverted
  in the init call). This has been around forever, but we have
  been saved by some other forgiving code that would reserve
  IRQ descriptors in this range, as the versatile is
  non-sparse.

When the IRQs were bumped up 32 steps so as to avoid using IRQ
zero and avoid touching the 16 legacy IRQs, things broke.

Introduce an explicit valid mask for the IRQs that are active
on the PIC/SIC, and pass that. Use the BIT() macro from
<linux/bitops.h> to make sure we hit the right bits, readily
defined in <mach/platform.h>.

This pull request adds initial support for the Tegra114 SoC, which
 integrates a quad-core ARM Cortex-A15 CPU. I'm proud to observe that we
 posted the initial versions of these patches before the final official
 announcement of this chip.
 
 These patches are enough to boot with a UART-based console, support the
 Dalmore and Pluto reference/evaluation boards, instantiate the GPIO and
 pinctrl drivers, and enable a cpuidle state. As yet, no clocks or
 storage devices are supported, but patches for those will follow shortly.
 
 This pull request is based on (most of) the previous pull request with
 tag tegra-for-3.9-soc-cpuidle, followed by a merge of the previous pull

ceca718f21 ARM: tegra: USB driver cleanup
The Tegra USB driver has a number of issues:
 
 1) The PHY driver isn't a true platform device, and doesn't implement
    the standard USB PHY API.
 
 2) struct device instance numbers were used to make decisions in the
    driver, rather than being parameterized by DT or platform data.
 
 This pull request solves issue (2), and lays the groundwork for solving
 issue (1). The work on issue (1) involved introducing new DT nodes for
 the USB PHYs, which in turn interacted with the Tegra common clock
 framework changes, due to the move of clock lookups into device tree.
 Hence, these USB driver changes are taken through the Tegra tree with
 acks from USB maintainers.

bda6f8e6cd ARM: tegra: Common Clock Framework rework
Tegra already supports the common clock framework, but had issues:
 
 1) The clock driver was located in arch/arm/mach-tegra/ rather than
    drivers/clk/.
 
 2) A single "Tegra clock" type was implemented, rather than separate
    clock types for PLL, mux, divider, ... type in HW.
 
 3) Clock lookups by device drivers were still driven by device name
    and connection ID, rather than through device tree.
 
 This pull request solves all three issues. This required some DT changes
 to add clocks properties, and driver changes to request clocks more
 "correctly". Finally, this rework allows all AUXDATA to be removed from
 Tegra board files, and various duplicate clock lookup entries to be
 removed from the driver.
 
 This pull request is based on the previous pull request, with tag
 tegra-for-3.9-cleanup.

   and connection ID, rather than through device tree.

This pull request solves all three issues. This required some DT changes
to add clocks properties, and driver changes to request clocks more
"correctly". Finally, this rework allows all AUXDATA to be removed from
Tegra board files, and various duplicate clock lookup entries to be
removed from the driver.

This pull request is based on the previous pull request, with tag
tegra-for-3.9-cleanup.

56bc911ac3 [media] s5p-fimc: Redefine platform data structure for fimc-is
Newer Exynos4 SoC are equipped with a local camera ISP that
controls external raw image sensor directly. Such sensors
can be connected through FIMC-LITEn (and MIPI-CSISn) IPs to
the ISP, which then feeds image data to the FIMCn IP. Thus
there can be two busses associated with an image source
(sensor). Rename struct s5p_fimc_isp_info describing external
image sensor (video decoder) to struct fimc_source_info to
avoid confusion. bus_type is split into fimc_bus_type and
sensor_bus_type. The bus type enumeration is extended to
include both FIMC Writeback input types.
The bus_type enumeration and the data structure name in the
board files are modified according to the above changes.

6689c87555 ARM: OMAP2+: Fix twl section warnings related to omap_twl4030_audio_init
With the recent twl related changes we can now get:

WARNING: arch/arm/mach-omap2/built-in.o(.text+0x15f88): Section mismatch in
reference from the function sdp3430_twl_gpio_setup() to the function

The function sdp3430_twl_gpio_setup() references
the function __init omap_twl4030_audio_init().
This is often because sdp3430_twl_gpio_setup lacks a __init
annotation or the annotation of omap_twl4030_audio_init is wrong.

Fix the use of USART on both at91sam9x5 and at91sam9n12. In DTS, the
atmel,use-dma-[rx|tx] property is present but a DMA channel cannot be used.
Indeed the connexion between the DMA engine and the slave is not implemented
yet in Device Tree.
Note however that this property is also used for PDC (private DMA) on older
SoCs. This is why the driver alone cannot determine the validity of this
property.

4b526ca5f6 ARM: i.MX25: clk: parent per5_clk to AHB clock
The mxc-timer on the imx25 needs to be derived from the AHB clock.
If a bootloader reparents this clock to the ipg_clk_highfreq, which according
to the datasheet is a valid operation, the system can/will produce lockups/
freezes after some time [1].

This can be forced with code like
	while(1)
                syscall(SYS_clock_gettime, CLOCK_REALTIME, &tp);

This was already fixed with the commit
	"i.MX25 GPT clock fix: ensure correct the clock source" [2],
for 3.1-rc2, but was lost, when i.MX was converted to the common clock framework
("ARM i.MX25: implement clocks using common clock framework") [3]

8310f9d295 ARM: OMAP3: igep0020: simplify GPIO LEDs dependencies
The IGEPv2 board has two user GPIO LEDs and one of them is
default to "on" to tell the user that the board booted correctly.

But to use these LEDs the config options CONFIG_LEDS_GPIO,
CONFIG_LEDS_TRIGGERS and CONFIG_LEDS_TRIGGER_DEFAULT_ON have to
be enabled.

Since only the default-on and default-off triggers were used
anyway, it is better to just use .default_state instead of
.default_trigger and not depend on CONFIG_LEDS_TRIGGER_*

Also, this is consistent with IGEPv2 Device Tree that uses
default-state instead of linux,default-trigger for the leds
device nodes. The LED names also have been updated to use the
same names used on omap3-igep0020.dtb.

8f0de0d62f ARM: OMAP2+: Get rid of custom OMAP_32K_TIMER_HZ
The timekeeping doesn't depend on HZ value in presence of fine grained
clocksource and hence there should not be any time drift because of HZ
value which was chosen to be divisor of 32768.

OMAP has been using HZ = 128 value to avoid any time drift issues
because of 32768 HZ clock. But with various measurements performed
with HZ = 100, no time drift is observed and it also proves the
point about HZ not having impact on time keeping on OMAP.

Very informative thread on this topic is here:

aecb9e1422 ARM: OMAP: make wakeupgen_lock raw
When applying RT patch on top of Linux, spinlocks are
implemented as RT-mutexes, which means they are preemptable.

Current GIC implementation on OMAP is using a spinlock
to protect against preemption. As it turns out, we need
to convert that lock into a raw_spinlock so that OMAP's
interrupt controller works as expected after RT-patch
is applied.

This patch is simply to decrease the amount of changes
RT-team needs to carry out of tree. It doesn't cause any

the cpu id value may include the cluster id and is no longer 0-3, so we
need to mask it in scu_power_mode to get the local cpu number. Since we
are only dealing with the cpu we are running on, the cluster id should
not ever be needed.

0c3c22f9c5 ARM: OMAP AM33XX: clock data: SET_RATE_PARENT in lcd path
LCDC clock node is a one that does not have set rate capability. It
just passes on the rate that is sent downstream by it's parent. While
lcdc clock parent and it's grand parent - dpll_disp_m2_ck and
dpll_disp_ck has the capability to configure rate.

And the default rates provided by LCDC clock's ancestors are not
sufficient to obtain pixel clock for current LCDC use cases, hence
currently display would not work on AM335x SoC's (with driver
modifications in platfrom independent way).

Hence inform clock framework to propogate set rate for LCDC clock as
well as it's parent - dpll_disp_m2_ck. With this change, set rate on
LCDC clock would get propogated till dpll_disp_ck via dpll_disp_m2_ck,
hence allowing the driver (same driver is used in DaVinci too) to set
rates using LCDC clock without worrying about platform dependent clock
details.

8a4da6e36c arm: arch_timer: move core to drivers/clocksource
The core functionality of the arch_timer driver is not directly tied to
anything under arch/arm, and can be split out.

This patch factors out the core of the arch_timer driver, so it can be
shared with other architectures. A couple of functions are added so
that architecture-specific code can interact with the driver without
needing to touch its internals.

The ARM_ARCH_TIMER config variable is moved out to
drivers/clocksource/Kconfig, existing uses in arch/arm are replaced with
HAVE_ARM_ARCH_TIMER, which selects it.

b2deabe3ba arm: arch_timer: add arch_counter_set_user_access
Several bits in CNTKCTL reset to 0, including PL0VTEN. For architectures
using the generic timer which wish to have a fast gettimeofday vDSO
implementation, these bits must be set to 1 by the kernel. For
architectures without a vDSO, it's best to leave the bits set to 0 for
now to ensure that if and when support is added, it's implemented sanely
architecture wide.

As the bootloader might set PL0VTEN to a value that doesn't correspond
to that which the kernel prefers, we must explicitly set it to the
architecture port's preferred value.

This patch adds arch_counter_set_user_access, which sets the PL0 access
permissions to that required by the architecture. For arch/arm, this
currently means disabling all userspace access.

1ba1cefc27 arm: arch_timer: divorce from local_timer api
Currently, the arch_timer driver is tied to the arm port, as it relies
on code in arch/arm/smp.c to setup and teardown timers as cores are
hotplugged on and off. The timer is registered through an arm-specific
registration mechanism, preventing sharing the driver with the arm64
port.

This patch moves the driver to using a cpu notifier instead, making it
easier to port.

4580104222 arm: arch_timer: add isbs to register accessors
Without the isbs in arch_timer_get_cnt{p,v}ct the cpu may speculate
reads and return stale values. This could be bad for code sensitive to
changes in expected deltas between calls (e.g. the delay loop).

Without isbs in arch_timer_reg_write the processor may reorder
instructions around enabling/disabling of the timer or writing the
compare value, which we probably don't want.

This patch adds isbs to prevent those issues.

b8e243431f arm: arch_timer: standardise counter reading
We're currently inconsistent with respect to our accesses to the
physical and virtual counters, mixing and matching the two.

This patch introduces and uses a function pointer for accessing the
correct counter based on whether we're using physical or virtual
interrupts. All current accesses to the counter accessors are redirected
through it.

When the driver is moved out to drivers/clocksource, there's the
possibility that code called before the timer code is initialised will
attempt to call arch_timer_read_counter (e.g. sched_clock for AArch64).
To avoid having to have to check whether the timer has been initialised
either in arch_timer_read_counter or one of it's callers, a default
implementation is assigned that simply returns 0.

Unconditionally register the PCI-E bus, even if the link is currently
down. When the link is brought up the bus can be scanned through
/sys/bus/pci/rescan or otherwise. Since the HW has no interrupt for
link up, userspace will have to take care of the timing.

An earlier version of this was contingent on CONFIG_HOTPLUG, but
that is being removed from the kernel.

This also fixes printing the link up/down message to be displayed

This adds the AB8500 core driver, which will be utilized by
the follow-on drivers for different ABx500 variants.
Sselect the driver from the DBX500_SOC, as this chip is
powering and clocking that SoC.

eea8e326ff ARM: imx: return zero in case next event gets a large increment
The return of v2_set_next_event() will lead to an infinite loop in
tick_handle_oneshot_broadcast() - "goto again;" with imx6q WAIT mode
(to be enabled).  This happens because when global event did not expire
any CPU local events, the broadcast device will be rearmed to a CPU
local next_event, which could be far away from now and result in a
max_delta_tick programming in set_next_event().

Fix the problem by detecting those next events with increments larger
than 0x7fffffff, and simply return zero in that case.

It leaves mx1_2_set_next_event() unchanged since only v2_set_next_event()
will be running with imx6q WAIT mode support.

Thanks Russell King for helping understand the problem.

f653b29825 ARM: OMAP2xxx: PM: clean up some crufty powerstate programming code
Don't attempt to put clockdomains to sleep; this should be handled by the
clock framework.  It should be enough to program the next-power-state,
and then let the code in omap_pm_clkdms_setup() deal with the rest.

Start out by programming the MPU and CORE powerdomains to stay ON.
Then control the MPU and CORE powerdomain states directly in
omap2_enter_full_retention() and omap2_enter_mpu_retention().  Not the
most optimal way to do it, but certainly is the most conservative until
OMAP2xxx PM is working again.

Get rid of the open-coded PM_PWSTCTRL_MPU writes in
omap2_enter_mpu_retention(); use the powerdomain code instead.

1cd96478cf ARM: OMAP3xxx: CPUIdle: optimize __omap3_enter_idle()
Avoid programming the MPU and CORE powerdomain next-power-state
registers if those powerdomains will never enter low-power states
(e.g., the state that people refer to as "C1").

To avoid making assumptions about CPUIdle states based on their order
in the list, use a flag to mark CPUIdle states that don't enter
powerdomain low-power states.

Avoid a previous-power-state register read on the MPU powerdomain
unless we know that the MPU was supposed to go OFF during the last
state transition.  Previous-power-state register reads can be very
expensive, so it's worth avoiding these when possible.

Since the CORE_L3 clockdomain can't go inactive unless the MPU is active,
there's little point blocking autoidle on the CORE_L3 clockdomain in "C1"
state, since we've programmed the MPU clockdomain to stay active.
Remove the unnecessary code.

1f629b7a3c ARM: S3C24XX: transform irq handling into a declarative form
The irqs available on the machine and even the bit settings in the
irq registers differ a lot through all the s3c24xx subarchitectures.
This results in each subarch having its own irq init which adds its
specific irqs to the base ones created in plat-s3c24xx/irq.c.

This of course makes a future move to devicetree hard to implement.

Therefore this patch transforms the base irq handling to a declarative
style, where the irq types as well as its parent/child relationship
gets read from a predefined datastructure, which later on can hopefully
be easily represented in devicetree too.

It should also be easy to include the subarch specific irqs here
in later patches, reducing code size and duplication.

It should not affect anything outside of the file, as the original
irq numbers and their handling are preserved (hopefully) correctly.

7e5fc77931 Merge branch 'pfc' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/sh-pinmux
From Simon Horman. Based on agreement between me, Paul Mundt, Linus
Walleij and Simon, we're mergning this large branch of pinctrl conversion
through arm-soc, even though it contains the corresponding conversions
for arch/sh. Main reason for this is tight dependencies (that will now
mostly be broken) between the arch/sh and mach-shmobile implementations.

There will be more of this in 3.10 to do device-tree bindings, but this is
the initial conversion.
