#1295113 — [PATCH 1/2] irqchip: add documentation for TS-4800 interrupt controller

This is an interrupt-controller implemented in an FPGA, to multiplex
interrupts generated from other IPs. The FPGA usually uses a GPIO as a
parent interrupt controller to notify that one of the multiplexed
interrupts has triggered.

+TS-4800 FPGA interrupt controller
+
+TS-4800 FPGA has an internal interrupt controller. When one of the
+interrupts is triggered, the SoC is notified, usually using a GPIO as
+parent interrupt source.
+
+Required properties:
+- compatible: should be "technologic,ts4800-irqc"
+- interrupt-controller: identifies the node as an interrupt controller
+- reg: physical base address of the controller and length of memory mapped
+  region
+- #interrupt-cells: specifies the number of cells needed to encode an interrupt
+  source, should be 1.
+- interrupt-parent: phandle to the parent interrupt controller this one is
+  cascaded from
+- interrupts: specifies the interrupt line in the interrupt-parent controller
