2017-11-07irqchip/exiu: Add support for Socionext Synquacer EXIU controllerArd Biesheuvel
The Socionext Synquacer SoC has an external interrupt unit (EXIU) that forwards a block of 32 configurable input lines to 32 adjacent level-high type GICv3 SPIs. The EXIU has per-interrupt level/edge and polarity controls, and mask bits that keep the outgoing lines de-asserted, even though the controller may still latch interrupt conditions that occur while the line is masked.
