[PATCH 05/15] irqchip: mips-gic: register IRQ domain with MIPS_GIC_IRQ_BASE

From: Paul Burton
Date: Fri May 22 2015 - 11:53:30 EST


On Malta, some IRQs are still referenced by hardcoded numbers relative
to MIPS_GIC_IRQ_BASE. When gic_init is called to register the GIC
without using device tree the irqbase argument allows this base to be
used. When the GIC is probed using device tree however the base is not
specified. This leads to conflicts between the GIC interrupts and other
interrupt controllers.

TODO: convert Malta (& SEAD3) to drop the hardcoded numbers instead
