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
