irq_domain: correct the debugfs file name

2012-04-11T04:39:17+00:00

The actual name of the irq_domain mapping debugfs file is
"irq_domain_mapping" not "virq_mapping".

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

2012-03-29T23:53:48+00:00

Pull more ARM updates from Russell King.

This got a fair number of conflicts with the  split, but
also with some other sparse-irq and header file include cleanups.  They
all looked pretty trivial, though.

irqdomain: Remove powerpc dependency from debugfs file

2012-03-29T20:31:02+00:00

The debugfs code is really generic for all platforms.  This patch removes the
powerpc-specific directory reference and makes it available to all
architectures.

irq: make SPARSE_IRQ an optionally hidden option

2012-01-26T02:37:42+00:00

On ARM, we don't want SPARSE_IRQ to be a user visible option. Make
SPARSE_IRQ visible based on MAY_HAVE_SPARSE_IRQ instead of depending
on HAVE_SPARSE_IRQ.

With this, SPARSE_IRQ is not visible on C6X and ARM.

irq: add irq_domain translation infrastructure

2011-07-28T07:32:04+00:00

This patch adds irq_domain infrastructure for translating from
hardware irq numbers to linux irqs.  This is particularly important
for architectures adding device tree support because the current
implementation (excluding PowerPC and SPARC) cannot handle
translation for more than a single interrupt controller.  irq_domain
supports device tree translation for any number of interrupt
controllers.

This patch converts x86, Microblaze, ARM and MIPS to use irq_domain
for device tree irq translation.  x86 is untested beyond compiling it,
irq_domain is enabled for MIPS and Microblaze, but the old behaviour is
preserved until the core code is modified to actually register an
irq_domain yet.  On ARM it works and is required for much of the new
ARM device tree board support.

PowerPC has /not/ been converted to use this new infrastructure.  It
is still missing some features before it can replace the virq
infrastructure already in powerpc (see documentation on
irq_domain_map/unmap for details).  Followup patches will add the
missing pieces and migrate PowerPC to use irq_domain.

SPARC has its own method of managing interrupts from the device tree
and is unaffected by this change.

genirq: Expand generic show_interrupts()

2011-03-25T16:04:20+00:00

Some archs want to print extra information for certain irq_chips which
is per irq and not per chip. Allow them to provide a chip callback to
print the chip name and the extra information.

PowerPC wants to print the LEVEL/EDGE type information. Make it configurable.
