The IP is present on multiple TI SoC architecture families including the OMAP architecture SoCs such as AM33xx, AM437x and AM57xx; and on a Keystone 2 architecture based 66AK2G SoC. It is also present on the Davinci based OMAPL138 SoCs and K3 architecture based AM65x and J721E SoCs as well. A PRUSS consists of dual 32-bit RISC cores (Programmable Real-Time Units, or PRUs), shared RAM, data and instruction RAMs, some internal peripheral modules to facilitate industrial communication, and an interrupt controller. The programmable nature of the PRUs provide flexibility to implement custom peripheral interfaces, fast real-time responses, or specialized data handling. The common peripheral modules include the following, - an Ethernet MII_RT module with two MII ports - an MDIO port to control external Ethernet PHYs - an Industrial Ethernet Peripheral (IEP) to manage/generate Industrial Ethernet functions - an Enhanced Capture Module (eCAP) - an Industrial Ethernet Timer with 7/9 capture and 16 compare events - a 16550-compatible UART to support PROFIBUS - Enhanced GPIO with async capture and serial support A typical usage scenario would be to load the application firmware into one or more of the PRU cores, initialize one or more of the peripherals and perform I/O through shared RAM from either a kernel driver or directly from userspace. This series contains the PRUSS platform driver. This is the parent driver for the entire PRUSS and is used for managing the subsystem level resources like various memories and the CFG module. It is responsible for the creation and deletion of the platform devices for the child PRU devices and other child devices (like Interrupt Controller, MDIO node and some syscon nodes) so that they can be managed by specific platform drivers.
