The Programmable Real-Time Unit Subsystem (PRUSS) contains a local interrupt controller (INTC) that can handle various system input events and post interrupts back to the device-level initiators. The INTC can support upto 64 input events with individual control configuration and hardware prioritization. These events are mapped onto 10 output interrupt lines through two levels of many-to-one mapping support. Different interrupt lines are routed to the individual PRU cores or to the host CPU, or to other devices on the SoC. Some of these events are sourced from peripherals or other sub-modules within that PRUSS, while a few others are sourced from SoC-level peripherals/devices. The PRUSS INTC platform driver manages this PRUSS interrupt controller and implements an irqchip driver to provide a Linux standard way for the PRU client users to enable/disable/ack/re-trigger a PRUSS system event. The system events to interrupt channels and output interrupts relies on the mapping configuration provided either through the PRU firmware blob (for interrupts routed to PRU cores) or via the PRU application's device tree node (for interrupt routed to the main CPU). In the first case the mappings will be programmed on PRU remoteproc driver demand (via irq_create_fwspec_mapping) during the boot of a PRU core and cleaned up after the PRU core is stopped. Reference counting is used to allow multiple system events to share a single channel and to allow multiple channels to share a single host event. The PRUSS INTC module is reference counted during the interrupt setup phase through the irqchip's irq_request_resources() and irq_release_resources() ops. This restricts the module from being removed as long as there are active interrupt users. The driver currently supports and can be built for OMAP architecture based AM335x, AM437x and AM57xx SoCs; Keystone2 architecture based 66AK2G SoCs and Davinci architecture based OMAP-L13x/AM18x/DA850 SoCs. All of these SoCs support 64 system events, 10 interrupt channels and 10 output interrupt lines per PRUSS INTC with a few SoC integration differences. NOTE: Each PRU-ICSS's INTC on AM57xx SoCs is preceded by a Crossbar that enables multiple external events to be routed to a specific number of input interrupt events. Any non-default external interrupt event directed towards PRUSS needs this crossbar to be setup properly. Co-developed-by: Suman Anna <s-anna@ti.com> Co-developed-by: Andrew F.
