Subject: [PATCH v7 0/1] Add PRUSS UIO driver support
Date: Wed, 2 Mar 2011 02:58:14 +0530 [thread overview]
Message-ID: <1299014895-2022-1-git-send-email-pratheesh@ti.com> (raw)
This patch series add support for PRUSS (Programmable Real-time Unit Sub
System) UIO driver in Texas Instruments DA850, AM18xx and OMAP-L138 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
