[PATCH v2 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. Signed-off-by: Damien Riegel Acked-by: Rob Herring --- Changes
