The PRUSS INTC present within the ICSSG supports more System Events (160 vs 64), more Interrupt Channels and Host Interrupts (20 vs 10) compared to the previous generation PRUSS INTC instances. The first 2 and the last 10 of these host interrupt lines are used by the PRU and other auxiliary cores and sub-modules within the ICSSG, with 8 host interrupts connected to MPU. The host interrupts 5, 6, 7 are also connected to the other ICSSG instances within the SoC and can be partitioned as per system integration through the board dts files. Enhance the PRUSS INTC driver to add support for this ICSSG INTC instance.
