Ben Dooks 3f1a567d8a [ARM] VIC: Fix resume sources usage
The resume_mask wasn't being checked in vic_set_wake()
to see if the IRQ was a valid wakeup source.

Ben Dooks c07f87f22e [ARM] VIC: Add power management device
Add power management support to the VIC by registering
each VIC as a system device to get suspend/resume
events going.

Since the VIC registeration is done early, we need to
record the VICs in a static array which is used to add
the system devices later once the initcalls are run. This
means there is now a configuration value for the number
of VICs in the system.

Linus Walleij 77f4025b5e [ARM] 5455/1: Fix IRQ noise from VIC code
The VIC code will attempt to perform som
default set_irq_chip() and set_irq_chip_data()
on all IRQs supported by the VIC, while the new
IRQ handling code strictly checks for the global
NR_IRQS to be respected also for these IRQs.

This patch will respect the interrupt mask passed
to the VIC driver and will prevent it from
attempting to call these functions on any unused
interrupts.

Ben Dooks a801cd6192 [ARM] VIC: Update asm/hardware/vic.h with PL192 information
The original arch/arm/include/asm/hardware/vic.h was
written for the PL190 ARM VIC implementation, and as
such does not have any information about the PL192
version.

Add details about the PL192 and PL190 specific registers
and any changes between the two units.

David Brownell 38c677cb9a [ARM] 3739/1: genirq updates: irq_chip, add and use irq_chip.name
Patch from David Brownell

ARM genirq cleanups/updates:

    - Start switching platforms to newer APIs
        * use "irq_chip" name, not "irqchip"
        * providing irq_chip.name

    - Show irq_chip.name in /proc/interrupts, like on x86.

This update a bit more than half of the ARM code.  The irq_chip.name
values were chosen to match docs (if I have them) or be otherwise
obvious ("FPGA", "CPLD", or matching the code).

Russell King 824b5b5e59 [ARM] Adapt vic.c to allow for multiple VICs in a system.
Some SoCs have multiple VIC devices.  Adapt the generic vic code
to allow multiple implementations to be handled.
