Barry Song 29eb51a728 irqchip: sirf: move from legacy mode to linear irqdomain
the series of patches for irqdomain core in 3.11 has broken sirf
irq which uses legacy mapping. all users fail in the new kernel
while setupping irq.

this patch moves to linear irqdomain and drop old legacy irqdomain
codes since we don't need it any more, and at the same time, it
also fixes the broken interrupts of sirfsoc in 3.11.

on the other hand, we actually only have 64 interrupt sources for
prima2 and atlas6, but there are 128 interrupt souces for marco
which uses GIC. in the legacy codes, sirf gpio also uses legacy
irqdomain, so to make gpio interrupt mapping not depend on the
prima2/atlas6/marco an use unified marco,we enlarge prima2/atlas6
interrupt number to 128. here we don't need this workaround any
more as sirf gpio also moved to linear mode before. so we move
SIRFSOC_NUM_IRQS back to 64 too.

Nicolas Pitre 10d9eb8a17 drivers: irq-chip: irq-gic: introduce gic_cpu_if_down()
When processors are about to hit low power states, the assertion of
standbywfi signal, triggered by the wfi instruction, is essential to
entering low power modes. If an IRQ is pending on the processor at the
time wfi is issued, the wfi instruction completes and the processor
restarts execution without asserting the standbywfi signal. Depending
on the platform power controller HW this behaviour can be acceptable or
not; if this behaviour must be prevented software should be provided
with a way to disable the routing of interrupts to the core IRQ pins.

On systems where raw GIC distributor interrupts are connected to the power
controller as wake-up events (hence the power controller still senses
IRQs and can wake up cores upon IRQ pending), the GIC CPU interface can
be disabled on power down, so that the GIC CPU IF output is gated and wfi
cannot complete, thereby preventing the standbywfi issue.

This patch adds a simple function to the GIC driver that allows to
disable the GIC CPU IF from power down procedures.

James Hogan b6ef9161e4 irq-imgpdc: add ImgTec PDC irqchip driver
Add irqchip driver for the ImgTec PowerDown Controller (PDC) as found in
the TZ1090. The PDC has a number of general system wakeup (SysWake)
interrupts (which would for example be connected to a power button or an
external peripheral), and a number of peripheral interrupts which can
also wake the system but are connected straight to specific low-power
peripherals (such as RTC or Infrared). It has a single interrupt output
for SysWakes, and individual interrupt outputs for each peripheral.

The driver demuxes the SysWake interrupt line, and passes the peripheral
interrupts straight through. It also handles the set_wake interrupt
operation to enable/disable the appropriate wake event bits.

Nicolas Pitre 1a6b69b654 ARM: gic: add CPU migration support
This is required by the big.LITTLE switcher code.

The gic_migrate_target() changes the CPU interface mapping for the
current CPU to redirect SGIs to the specified interface, and it also
updates the target CPU for each interrupts to that CPU interface
if they were targeting the current interface.  Finally, pending
SGIs for the current CPU are forwarded to the new interface.

Because Linux does not use it, the SGI source information for the
forwarded SGIs is not preserved.  Neither is the source information
for the SGIs sent by the current CPU to other CPUs adjusted to match
the new CPU interface mapping.  The required registers are banked so
only the target CPU could do it.

Paul Gortmaker 8c37bb3ac9 clocksource+irqchip: delete __cpuinit usage from all related files
The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications.  For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.

After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out.  Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.

This removes all the drivers/clocksource and drivers/irqchip uses of
the __cpuinit macros from all C files.

Linus Torvalds ee1a8d402e ARM SoC device tree changes
These changes from 30 individual branches for the most part update device
 tree files, but there are also a few source code changes that have crept
 in this time, usually in order to atomically move over a driver from
 using hardcoded data to DT probing.
 
 A number of platforms change their DT files to use the C preprocessor,
 which is causing a bit of churn, but that is hopefully only this once.
 
 There are a few conflicts with the other branches unfortunately:
 
 * in exynos5440.dtsi and kirkwood-6281.dtsi, device nodes are added
   from multiple branches. Need to be careful to have the right
   set of closing braces as git gets this one wrong.
 
 * In kirkwood.dtsi, one 'ranges' line got split into two lines, while
   another line got added. Order of the lines does not matter.
 
 * in sama5d3.dtsi, some cleanup was merged the wrong way, causing
   a bogus conflict. We want the 'dmas' and 'dma-names' properties
   to get added here.
 
 * Two lines got removed independently in arch/arm/mach-mxs/mach-mxs.c
 
 * Contents get added independently in arch/arm/mach-omap2/cclock33xx_data.c

Shawn Guo 8b6fd65264 irqchip: gic: call gic_cpu_init() as well in CPU_STARTING_FROZEN case
Commit c011470 (irqchip: gic: Perform the gic_secondary_init() call via
CPU notifier) moves gic_secondary_init() that used to be called in
.smp_secondary_init hook into a notifier call.  But it changes the
system behavior a little bit.  Before the commit, gic_cpu_init()
is called not only when kernel brings up the secondary cores but also
when system resuming procedure hot-plugs the cores back to kernel.
While after the commit, the function will not be called in the latter
case, where the 'action' will not be CPU_STARTING but
CPU_STARTING_FROZEN.  This behavior difference at least causes the
following suspend/resume regression on imx6q.

Markus Pargmann b5f83e9b06 ARM: mxs: icoll: Fix interrupts gpio bank 0
The mxs interrupt controller does not support polling for interrupts,
but the driver still does it, which is a relict from
pre-MULTI_IRQ_HANDLER times.

The existing code assumes that 0x7f means no interrupt, but this value
is an actually valid irq number, namely gpio bank 0's irq. This results
in the driver not detecting when irq 0x7f is active which makes the
machine effectively dead lock.

This patch removes the interrupt poll loop and allows usage of gpio0
interrupt without an infinite loop.

Linus Torvalds bb9055b274 ARM: late Exynos multiplatform changes
These continue the multiplatform support for exynos, adding support
 for building most of the essential drivers (clocksource, clk, irqchip)
 when combined with other platforms. As a result, it should become
 really easy to add full multiplatform exynos support in 3.11, although
 we don't yet enable it for 3.10.
 
 The changes were not included in the earlier multiplatform series
 in order to avoid clashes with the other Exynos updates.
 
 This also includes work from Tomasz Figa to fix the pwm clocksource
 code on Exynos, which is not strictly required for multiplatform,
 but related to the other patches in this set and needed as a bug
 fix for at least one board.

Linus Torvalds 1bf25e78af ARM: arm-soc: late cleanups
These are cleanups and smaller changes that either depend on earlier
 feature branches or came in late during the development cycle.
 We normally try to get all cleanups early, so these are the exceptions:
 
 - A follow-up on the clocksource reworks, hopefully the last time
   we need to merge clocksource subsystem changes through arm-soc.
   A first set of patches was part of the original 3.10 arm-soc cleanup
   series because of interdependencies with timer drivers now moved out
   of arch/arm.
 
 - Migrating the SPEAr13xx platform away from using auxdata for DMA
   channel descriptions towards using information in device tree,
   based on the earlier SPEAr multiplatform series
 
 - A few follow-ups on the Atmel SAMA5 support and other changes
   for Atmel at91 based on the larger at91 reworks.
 
 - Moving the armada irqchip implementation to drivers/irqchip
 
 - Several OMAP cleanups following up on the larger series already
   merged in 3.10.

Linus Torvalds 6fa52ed33b ARM: arm-soc driver changes for 3.10
This is a rather large set of patches for device drivers that for one
 reason or another the subsystem maintainer preferred to get merged
 through the arm-soc tree. There are both new drivers as well as
 existing drivers that are getting converted from platform-specific
 code into standalone drivers using the appropriate subsystem
 specific interfaces.
 
 In particular, we can now have pinctrl, clk, clksource and irqchip
 drivers in one file per driver, without the need to call into
 platform specific interface, or to get called from platform specific
 code, as long as all information about the hardware is provided
 through a device tree.
 
 Most of the drivers we touch this time are for clocksource. Since
 now most of them are part of drivers/clocksource, I expect that we
 won't have to touch these again from arm-soc and can let the
 clocksource maintainers take care of these in the future.
 
 Another larger part of this series is specific to the exynos platform,
 which is seeing some significant effort in upstreaming and
 modernization of its device drivers this time around, which
 unfortunately is also the cause for the churn and a lot of the
 merge conflicts.
 
 There is one new subsystem that gets merged as part of this series:
 the reset controller interface, which is a very simple interface
 for taking devices on the SoC out of reset or back into reset.
 Patches to use this interface on i.MX follow later in this merge
 window, and we are going to have other platforms (at least tegra
 and sirf) get converted in 3.11. This will let us get rid of
 platform specific callbacks in a number of platform independent
 device drivers.

 patch in this branch to a early version of multiplatform conversion,
 but it ended up being reverted due to need of more bake time. The
 revert commit is part of the branch since it would have required
 rebasing multiple dependent branches and they were stable by then.

The s3c24xx_init_intc and s3c2412_init_irq functions are only called
at init time, and they call functions already marked __init, so they
should be marked in the same way. This was reported as

WARNING: vmlinux.o(.text+0x19e0b4): Section mismatch in reference from the function s3c2412_init_irq() to the function .init.text:s3c24xx_init_intc.constprop.8()
The function s3c2412_init_irq() references
the function __init s3c24xx_init_intc.constprop.8().
This is often because s3c2412_init_irq lacks a __init
annotation or the annotation of s3c24xx_init_intc.constprop.8 is wrong.

Since we want to move to using the linear IRQ domain in the
future, we cannot rely on the irq numbers to be contiguous
and need to look up the irq from the hwirq using the domain.

This also turns the bogus comparison with NR_IRQ into a
more meaningful check to see if the number has a valid mapping.

Arnd Bergmann 863a08dc8b irqchip: exynos: pass irq_base from platform
The platform code knows the IRQ base, while the irqchip driver
should really not. This is a littly hacky because we still
hardwire the IRQ base to 160 for the combiner in the DT case,
when we should really use -1. Removing that line will cause
a linear IRQ domain to be use, as we should.

Arnd Bergmann d34f03d4a1 irqchip: exynos: allocate combiner_data dynamically
The number of combiners on a given SoC is a platform specific
constant, and we cannot encode this number on a multiplatform
kernel since the header file defining it is not available.

Allocating the structure dynamically ends up cleaner anyway
since we keep all the data local.

Arnd Bergmann 6761dcfe8c irqchip: exynos: pass max combiner number to combiner_init
We can find out the number of combined IRQs from the device
tree, but in case of ATAGS boot, the driver currently uses
hardcoded values based on the SoC type. We can't do that
in general for a multiplatform kernel, so let's instead pass
this information from platform code directly in case of
ATAGS boot.

Thomas Petazzoni 5ec69017cc irqchip: armada-370-xp: slightly cleanup irq controller driver
In preparation for the introduction of MSI support in the IRQ
controller driver, we clarify the implementation of IPI using
additional defines for the manipulation of doorbells. Just like IPIs
are implemented using doorbells, MSIs will also use doorbells, so it
makes sense to do this preparatory cleanup first.

Thomas Petazzoni b313ada8c7 irqchip: armada-370-xp: move IRQ handler to avoid forward declaration
If we move the IRQ handler function above the initialization function,
we avoid a forward declaration. This wasn't done as part of the
previous commit, in order to increase the readibility of the previous
commit, who was also moving the IRQ controller driver from arch/arm to
drivers/irqchip.

Thomas Petazzoni 9339d432fd irqchip: move IRQ driver for Armada 370/XP
When the Marvell Armada 370/XP support was included in the kernel, the
drivers/irqchip/ directory didn't exist and the minimal infrastructure
in it also didn't exist. Now that we have those things in place, we
move the Armada 370/XP IRQ controller driver from
arch/arm/mach-mvebu/irq-armada-370-xp.c to
drivers/irqchip/irq-armada-370-xp.c.

Note in order to reduce code movement and therefore ease the review of
this patch, we intentionally introduce a forward declaration of
armada_370_xp_handle_irq(). It is in fact not needed because this
handler can now simply be implemented before
armada_370_xp_mpic_of_init(). That will be done in the next commit.

Maxime Ripard d7fbc6ca35 irqchip: sunxi: Rename sunxi to sun4i
During the introduction of the Allwinner SoC platforms, sunxi was
initially meant as a generic name for all the variants of the Allwinner
SoC.

It was ok at the time of the support of only the A10 and A13 that
looks pretty much the same, but it's beginning to be troublesome with
the future addition of the Allwinner A31 (sun6i) that is quite
different, and would introduce some weird logic, where sunxi would
actually mean in some case sun4i and sun5i but without sun6i...

Moreover, it makes the compatible strings naming scheme not consistent
with other architectures, where usually for this kind of compability, we
just use the oldest SoC name that has this IP, so let's do just this.

The list in used was from the s3c2450, a close cousin of the s3c2416.
As it's not possible to distinguish between the s3c2416 and s3c2450
the additional interrupts of the s3c2450 will only be available thru
devicetree later.

Bastian Hecht 427cc72027 irqchip: intc-irqpin: Add support for shared interrupt lines
On some hardware we don't have a 1-1 mapping from the external
interrupts coming from INTC to the GIC SPI pins. We can however
share lines to demux incoming IRQs on these SoCs.

This patch enables the intc_irqpin driver to detect requests for shared
interrupt lines and demuxes them properly by querying the INTC INTREQx0A
registers.

If you need multiple shared intc_irqpin device instances, be sure to mask
out all interrupts on the INTC that share the one line before you start
to register them. Else you run into IRQ floods that would be caused by
interrupts for which no handler has been set up yet when the first
intc_irqpin device is registered.

Magnus Damm fbc83b7f59 irqchip: Renesas IRQC driver
This patch adds a driver for external IRQ pins connected
to the IRQC hardware block on recent SoCs from Renesas.

The IRQC hardware block is used together with more
recent ARM based SoCs using the GIC. As usual the GIC
requires external IRQ trigger setup somewhere else
which in this particular case happens to be IRQC.

This driver implements the glue code needed to configure
IRQ trigger and also handle mask/unmask and demux of
external IRQ pins hooked up from the IRQC to the GIC.

Tested on r8a73a4 but is designed to work with a wide
range of SoCs. The driver requires one GIC SPI per
external IRQ pin to operate.  Each driver instance
will handle up to 32 external IRQ pins.

The SoCs using this driver are currently mainly used
together with regular platform devices so this driver
allows configuration via platform data to support things
like static interrupt base address. DT support will
be added incrementally in the not so distant future.

Magnus Damm 443580486e irqchip: Renesas INTC External IRQ pin driver
This patch adds a driver for external IRQ pins connected
to the INTC block on recent SoCs from Renesas.

The INTC hardware block usually contains a rather wide
range of features ranging from external IRQ pin handling
to legacy interrupt controller support. On older SoCs
the INTC is used as a general purpose interrupt controller
both for external IRQ pins and on-chip devices.

On more recent ARM based SoCs with Cortex-A9 the main
interrupt controller is the GIC, but IRQ trigger setup
still need to happen in the INTC hardware block.

This driver implements the glue code needed to configure
IRQ trigger and also handle mask/unmask and demux of
external IRQ pins hooked up from the INTC to the GIC.

Tested on sh73a0 and r8a7779. The hardware varies quite
a bit with SoC model, for instance register width and
bitfield widths vary wildly. The driver requires one GIC
SPI per external IRQ pin to operate.  Each driver instance
will handle up to 8 external IRQ pins.

The SoCs using this driver are currently mainly used
together with regular platform devices so this driver
allows configuration via platform data to support things
like static interrupt base address. DT support will
be added incrementally in the not so distant future.

Linus Torvalds b274776c54 arm-soc: cleanups
A large number of cleanups, all over the platforms. This is dominated
 largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
 others moving code out of arch/arm into more appropriate subsystems.
 The clocksource and irqchip drivers are now abstracted to the point
 where platforms that are already cleaned up do not need to even specify
 the driver they use, it can all get configured from the device tree
 as we do for normal device drivers. The clocksource changes basically
 touch every single platform in the process.
 
 We further clean up the use of platform specific header files here,
 with the goal of turning more of the platforms over to being
 "multiplatform" enabled, which implies that they cannot expose
 their headers to architecture independent code any more.
 
 It is expected that no functional changes are part of the cleanup.
 The overall reduction in total code lines is mostly the result of
 removing broken and obsolete code.

Rob Herring a900e5d997 ARM: exynos: move exynos4210-combiner to drivers/irqchip
Exynos boot is broken with commit 0529e315 (ARM: use common irqchip_init
for GIC init). This commit split the irqchip initialization into 2 calls
to of_irq_init. This does not work because of_irq_init requires interrupt
parents to be in the match list.

Rather than reverting exynos changes, make it do the proper thing by using
IRQCHIP_DECLARE. This requires moving the combiner code to drivers/irqchip.
