[PATCH v4 1/3] dt-bindings: interrupt-controller: Add Actions SIRQ controller binding

From: Cristian Ciocaltea <cristian.ciocaltea@gmail.com>
Date: 2020-08-16 11:38:06
Also in: linux-arm-kernel, lkml
Subsystem: arm/actions semi architecture, irqchip drivers, open firmware and flattened device tree bindings, the rest · Maintainers: Andreas Färber, Manivannan Sadhasivam, Thomas Gleixner, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

Actions Semi Owl SoCs SIRQ interrupt controller is found in S500, S700
and S900 SoCs and provides support for connecting up to 3 independent
external interrupt controllers through dedicated SIRQ pins.
