irqchip: gic: Perform the gic_secondary_init() call via CPU notifier

2013-03-26T16:12:02+00:00

All the calls to gic_secondary_init() pass 0 as the first argument.
Since this function is called on each CPU when starting, it can be done
in a platform-independent way via a CPU notifier registered by the GIC
code.

ARM: vexpress: extend the MPIDR range used for pen release check

2013-01-24T12:19:23+00:00

In ARM multi-cluster systems the MPIDR affinity level 0 cannot be used as a
single cpu identifier, affinity levels 1 and 2 must be taken into account as
well.
This patch extends the MPIDR usage to affinity levels 1 and 2 in versatile
secondary cores start up code in order to compare the passed pen_release
value with the full-blown affinity mask.

irqchip: Move ARM gic.h to include/linux/irqchip/arm-gic.h

2013-01-12T16:47:32+00:00

Now that we have GIC moved to drivers/irqchip and all GIC DT init for
platforms using irqchip_init, move gic.h and update the remaining
includes.

ARM: GIC: remove direct use of gic_raise_softirq

2013-01-10T17:45:43+00:00

In preparation of moving gic code to drivers/irqchip, remove the direct
platform dependencies on gic_raise_softirq. Move the setup of
smp_cross_call into the gic code and use arch_send_wakeup_ipi_mask
function to trigger wake-up IPIs.

Merge tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2012-12-12T20:05:15+00:00

Pull ARM SoC updates from Olof Johansson:
 "This contains the bulk of new SoC development for this merge window.

  Two new platforms have been added, the sunxi platforms (Allwinner A1x
  SoCs) by Maxime Ripard, and a generic Broadcom platform for a new
  series of ARMv7 platforms from them, where the hope is that we can
  keep the platform code generic enough to have them all share one mach
  directory.  The new Broadcom platform is contributed by Christian
  Daudt.

  Highbank has grown support for Calxeda's next generation of hardware,
  ECX-2000.

  clps711x has seen a lot of cleanup from Alexander Shiyan, and he's
  also taken on maintainership of the platform.

  Beyond this there has been a bunch of work from a number of people on
  converting more platforms to IRQ domains, pinctrl conversion, cleanup
  and general feature enablement across most of the active platforms."

Fix up trivial conflicts as per Olof.

ARM: plat-versatile: move FPGA irq driver to drivers/irqchip

2012-11-04T17:09:12+00:00

This moves the Versatile FPGA interrupt controller driver, used in
the Integrator/AP, Integrator/CP and some Versatile boards, out
of arch/arm/plat-versatile and down to drivers/irqchip where we
have consensus that such drivers belong. The header file is
consequently moved to .

ARM: plat-versatile: use simple irqdomain for FPGA IRQ

2012-10-26T23:05:06+00:00

This switches the FPGA IRQ driver over to using the simple IRQ
domain. We can then use the same codepath for this in the
DT and non-DT cases.

To be able to use quicker irq_find_mapping() in the handlers
we first call irq_create_mapping() on all the valid HW IRQ
numbers so that descriptors will be created for them in the
DT case where a linear domain will be the outcome of the
call.

Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm

2012-10-07T12:20:57+00:00

Pull ARM updates from Russell King:
 "This is the first chunk of ARM updates for this merge window.
  Conflicts are expected in two files - asm/timex.h and
  mach-integrator/integrator_cp.c.  Nothing particularly stands out more
  than anything else.

  Most of the growth is down to the opcodes stuff from Dave Martin,
  which is countered by Rob's patches to use more of the asm-generic
  headers on ARM."

(A few more conflicts grew since then, but it all looked fairly trivial)
