[PATCH V2 00/19] irqchip: crossbar: driver fixes

[Sricharan R]

This series does some cleanups, fixes for handling two interrupts
getting mapped twice to same crossbar and provides support for
hardwired IRQ and crossbar definitions.

On certain platforms such as DRA7, SPIs 0, 1, 2, 3, 5, 6, 10,
131, 132, 133 are direct wired to hardware blocks bypassing
crossbar. This quirky implementation is *NOT* supposed to be the
expectation of crossbar hardware usage. This series adds support
to represent such hard-wired irqs through DT and avoid generic
allocation/programming of crossbar in the driver.

This way of supporting hard-wired irqs was a result of
the below discussions.

Based on 3.15 mainline.

The fixes series[1] earlier posted is merged in to this.
