This patch series add support for PRUSS (Programmable Real-time Unit Sub System) UIO driver in Texas Instruments DA850, AM18xx and OMAPL1-38 processors. PRUSS is programmable RISC core which can be used to implement Soft IPs (eg:- DMA, CAN, UART,SmartCard) and Industrial communications data link layers (eg:- PROFIBUS). UIO driver exposes PRUSS resources like memory and interrupts to user space application.PRUSS UIO application API can be used to control PRUs in PRUSS, setup PRU INTC, load firmware to PRUs and implement IPC between Host processor and PRUs. More information on PRUSS and UIO linux user space API available in the links below
