7 title: TI PRU-ICSS Local Interrupt Controller
10 - Suman Anna <s-anna@ti.com>
13 Each PRU-ICSS has a single interrupt controller instance that is common
22 The property "ti,irqs-reserved" is used for denoting the connection
24 defined, it implies that all the PRUSS INTC output interrupts 2 through 9
30 through 19) are connected to new sub-modules within the ICSSG instances.

11 - Suman Anna <s-anna@ti.com>
15 The Programmable Real-Time Unit and Industrial Communication Subsystem
16 (PRU-ICSS a.k.a. PRUSS) is present on various TI SoCs such as AM335x, AM437x,
17 Keystone 66AK2G, OMAP-L138/DA850 etc. A PRUSS consists of dual 32-bit RISC
18 cores (Programmable Real-Time Units, or PRUs), shared RAM, data and
23 peripheral interfaces, fast real-time responses, or specialized data handling.
