[PATCH 0/5] GIC OF bindings

[Rob Herring]

From: Rob Herring <rob.herring at calxeda.com>

This series introduces of_irq_init to scan the device tree for interrupt
controller nodes and call their init functions in proper order. The GIC
init function is then called from this function. The platform code then
looks something like this:

const static struct of_device_id irq_match[] = {
	{ .compatible = "arm,cortex-a9-gic", .data = gic_of_init, },
	{}
};

static void __init highbank_init_irq(void)
{
	of_irq_init(irq_match);
}

The binding for GIC PPIs is now done with a 3rd interrupt cell to specify
a cpu mask for which cpu the PPI is connected to. This was discussed at LPC
and suggested by Grant.

I dropped the public intc_desc struct. The the interrupt controller's node
and the interrupt parent's node are passed in directly to the controller's
init function. The linux irq assignment is now done dynamically using
irq_alloc_descs.

The first 2 patches are minor fixes to irqdomains.
