TISCI abstracts the handling of IRQ routes where interrupt sources are not directly connected to host interrupt controller. This series adds support for: - TISCI commands needed for IRQ configuration - Interrupt Router(INTR) and Interrupt Aggregator(INTA) drivers More information on TISCI IRQ management can be found here[1]. Complete TISCI resource management information can be found here[2]. AM65x SoC related TISCI information can be found here[3]. INTR and INTA related information can be found in TRM[4].
I didn't read the specs but from what you described in INTA and INTR bindings, does the flow of IRQs like below ? Device IRQ(e.g USB) -->INTR-->INTA--->HOST IRQ controller(GIC) The confusing part is aggregator and can multiplex as well as grouping but seems like its event grouping or multiplexing than actual device IRQ grouping or multi-plexsing. What am I missing ? Regards,S antosh
