+title: Keystone 2 IRQ controller IP
+

+ - Grygorii Strashko <grygorii.strashko@ti.com>
+
+description:
+ On Keystone SOCs, DSP cores can send interrupts to ARM host using the IRQ
+ controller IP. It provides 28 IRQ signals to ARM. The IRQ handler running on
+ HOST OS can identify DSP signal source by analyzing SRCCx bits in IPCARx
+ registers. This is one of the component used by the IPC mechanism used on
+ Keystone SOCs.
