Rob Herring d17cab4451 irqchip: Kill off set_irq_flags usage
set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:

IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.

Thomas Gleixner bd0b9ac405 genirq: Remove irq argument from irq flow handlers
Most interrupt flow handlers do not use the irq argument. Those few
which use it can retrieve the irq number from the irq descriptor.

Remove the argument.

Search and replace was done with coccinelle and some extra helper
scripts around it. Thanks to Julia for her help!

Thomas Gleixner 14873aa1d1 irqchip/mmp: Prepare icu_mux_irq_demux for irq argument removal
The irq argument of most interrupt flow handlers is unused or merily
used instead of a local variable. The handlers which need the irq
argument can retrieve the irq number from the irq descriptor.

Search and update was done with coccinelle and the invaluable help of
Julia Lawall.

Joel Porquet 41a83e06e2 irqchip: Prepare for local stub header removal
The IRQCHIP_DECLARE macro moved to to 'include/linux/irqchip.h', so
the local irqchip.h became an empty shell, which solely includes
include/linux/irqchip.h

Include the global header in all irqchip drivers instead of the local
header, so we can remove it.

Linus Torvalds dfc25e4503 ARM: SoC: cleanups for 3.15
These cleanup patches are mainly move stuff around and should all
 be harmless. They are mainly split out so that other branches can
 be based on top to avoid conflicts.
 
 Notable changes are:
 
 * We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
   longer used. (Uwe Kleine-König)
 * The Qualcomm MSM platform is split out into legacy mach-msm and
   new-style mach-qcom, to allow easier maintainance of the new
   hardware support without regressions. (Kumar Gala)
 * A rework of some of the Kconfig logic to simplify multiplatform
   support (Rob Herring)
 * Samsung Exynos gets closer to supporting multiplatform (Sachin
   Kamat and others)
 * mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
 * at91 gains some common clock framework support (Alexandre Belloni,
   Jean-Jacques Hiblot and other French people).
