From 9f1463b86c13277d0bd88d5ee359577ef40f4da7 Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Tue, 30 Apr 2019 15:42:27 +0530 Subject: irqchip/ti-sci-inta: Add support for Interrupt Aggregator driver Texas Instruments' K3 generation SoCs has an IP Interrupt Aggregator which is an interrupt controller that does the following: - Converts events to interrupts that can be understood by an interrupt router. - Allows for multiplexing of events to interrupts. Configuration of the interrupt aggregator registers can only be done by a system co-processor and the driver needs to send a message to this co processor over TISCI protocol. Add the required infrastructure to allow the allocation and routing of these events.
