of/irq: Fix lookup to use 'interrupts-extended' property first

2014-08-16T08:03:58+00:00

In case the Device Tree blob passed by the boot agent supplies both an
'interrupts-extended' and an 'interrupts' property in order to allow for
older kernels to be usable, prefer the new-style 'interrupts-extended'
property which conveys a lot more information.

This allows us to have bootloaders willingly maintaining backwards
compatibility with older kernels without entirely deprecating the
'interrupts' property.

Update the bindings documentation to describe a situation where both the
'interrupts-extended' and the 'interrupts' property are present, and
which one takes precedence over the other.

Merge branch 'irqchip/atmel-aic' into irqchip/core

Topic branch set up to facilitate merging the rest of the series which
removes the driver from arch code.

irqchip: atmel-aic: Move binding doc to interrupt-controller directory

2014-07-17T13:30:17+00:00

Move atmel aic driver doc to the interrupt-controller directory as the new
driver now lays in drivers/irqchip/atmel-aic.c.

irqchip: or1k-pic: Migrate from arch/openrisc/

2014-07-01T12:15:06+00:00

In addition to consolidating the or1k-pic with other interrupt
controllers, this makes OpenRISC less tied to its on-cpu
interrupt controller.

All or1k-pic specific parts are moved out of irq.c and into
drivers/irqchip/irq-or1k-pic.c

In that transition, the functionality have been divided into
three chip variants.
One that handles level triggered interrupts, one that handles edge
triggered interrupts and one that handles the interrupt
controller that is present in the or1200 OpenRISC cpu
implementation.

Merge tag 'soc-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2014-04-05T21:19:54+00:00

Pull ARM SoC specific changes from Arnd Bergmann:
 "Lots of changes specific to one of the SoC families.  Some that stick
  out are:

   - mach-qcom gains new features, most importantly SMP support for the
     newer chips (Stephen Boyd, Rohit Vaswani)
   - mvebu gains support for three new SoCs: Armada 375, 380 and 385
     (Thomas Petazzoni and Free-electrons team)
   - SMP support for Rockchips (Heiko Stübner)
   - Lots of i.MX changes (Shawn Guo)
   - Added support for BCM5301x SoC (Hauke Mehrtens)
   - Multiplatform support for Marvell Kirkwood and Dove (Andrew Lunn
     and Sebastian Hesselbarth doing the final part of a long journey)
   - Unify davinci platforms and remove obsolete ones (Sekhar Nori, Arnd
     Bergmann)"

2014-03-14T12:43:32+00:00

The Allwinner A10 compatibles were following a slightly different compatible
patterns than the rest of the SoCs for historical reasons. Change the compatibles
to match the other pattern in the irq controller driver for consistency.

Revert irqchip: irq-dove: Add PMU interrupt controller

2014-03-04T10:10:17+00:00

This reverts commit 40b367d95fb3d60fc1edb9ba8f6ef52272e48936.

Russell King has raised the idea of creating a proper PMU driver for
this SoC that would incorporate the functionality currently in this
driver. It would also cover the use case for the graphics subsystem on
this SoC.

To prevent having to maintain the devicetree ABI for this limited
interrupt-handler driver, we revert the driver before it hits a mainline
tagged release (eg v3.15).
