Pull IRQ fixes from Ingo Molnar:
 "Mostly irqchip driver fixes, but also an irq core crash fix and a
  build fix"

* 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  irqchip/mxs: Add missing set_handle_irq()
  irqchip/atmel-aic: Fix wrong bit operation for IRQ priority
  irqchip/gic-v3-its: Recompute the number of pages on page size change
  base: Export platform_msi_domain_[alloc,free]_irqs
  of: MSI: Simplify irqdomain lookup
  irqdomain: Allow domain lookup with DOMAIN_BUS_WIRED token
  irqchip: Fix dependencies for archs w/o HAS_IOMEM
  irqchip/s3c24xx: Mark init_eint as __maybe_unused
  genirq: Validate action before dereferencing it in handle_irq_event_percpu()

of: MSI: Simplify irqdomain lookup

2016-01-26T15:00:15+00:00

So far, when trying to associate a device with its MSI domain,
we first lookup the domain using a MSI token, and if this
doesn't return anything useful, we pick up any domain matching
the same node.

This logic is broken for two reasons:
1) Only the generic MSI code (PCI or platform) sets this token
   to PCI/MSI or platform MSI. So we're guaranteed that if there
   is something to be found, we will find it with the first call.
2) If we have a convoluted situation where:
   - a single node implements both wired and MSI interrupts
   - MSI support for that HW hasn't been compiled in
   we'll end up using the wired domain for MSIs anyway, and things
   break badly.

So let's just remove __of_get_msi_domain, and replace it by a direct
call to irq_find_matching_host, because that's what we really want.

drivers/of: Export OF changeset functions

2016-01-13T22:10:37+00:00

The PowerNV PCI hotplug driver is going to use the OF changeset
to manage the changed device sub-tree. This exports those OF
changeset functions for that.

mdio: remove an unneed condition

2016-01-12T16:51:57+00:00

It used to be that mdio->irq was a pointer but after e7f4dc3536a4
('mdio: Move allocation of interrupts into core') it's an array inside
the mdio struct so it can never be NULL.

mdio: Add support for mdio drivers.

2016-01-07T19:31:27+00:00

Not all devices on an MDIO bus are PHYs. Meaning not all MDIO drivers
are PHY drivers. Add support for generic MDIO drivers.

phy: Add API for {un}registering an mdio device to a bus.

2016-01-07T19:31:26+00:00

Rather than have drivers directly manipulate the mii_bus structure,
provide and API for registering and unregistering devices on an MDIO
bus, and performing lookups.

2016-01-07T19:31:26+00:00

We will soon support devices other than phys on the mdio bus. Look at
a child's compatibility string to determine if it is a phy, before
registering a phy device.

Not all devices attached to an MDIO bus are phys. So add an
mdio_device structure to represent the generic parts of an mdio
device, and place this structure into the phy_device.

mdio: Move allocation of interrupts into core

2016-01-07T19:31:26+00:00

Have mdio_alloc() create the array of interrupt numbers, and
initialize it to POLLING. This is what most MDIO drivers want, so
allowing code to be removed from the drivers.
