Add the Interrupt controller node for the Interrupt Router present within the Main NavSS module. This Interrupt Router can route 192 interrupts to the GIC_SPI in 3 sets of 64 interrupts each. Note that the last set is reserved for the host ID A72_3 for hypervisor usecases, so the node is added only with 2 sets for the Linux kernel context (host id A72_2). This is specified through the ti,sci-rm-range-girq property. Signed-off-by: Suman Anna <s-anna@xxxxxx> --- Hi Tero, This patch depends on the J721E series [1] from Nishanth.
