ISS),14Which contains several components that can be categorized in 3 big groups:15 16- Interfaces (2 Interfaces: CSI2-A & CSI2-B/CCP2)17- ISP (Image Signal Processor)18- SIMCOP (Still Image Coprocessor)19 20For more information, please look in [#f1]_ for latest version of:21"OMAP4430 Multimedia Device Silicon Revision 2.x"22 23As of Revision AB, the ISS is described in detail in section 8.24 25This driver is supporting **only** the CSI2-A/B interfaces for now.26 27It makes use of the Media Controller framework [#f2]_, and inherited most of the28code from OMAP3 ISP driver (found under drivers/media/platform/ti/omap3isp/\*),29except that it doesn't need an IOMMU now for ISS buffers memory mapping.30 31Supports usage of MMAP buffers only (for now).32 33Tested platforms34----------------35 36- OMAP4430SDP, w/ ES2.1 GP & SEVM4430-CAM-V1-0 (Contains IMX060 & OV5640, in37 which only the last one is supported, outputting YUV422 frames).38 39- TI Blaze MDP, w/ OMAP4430 ES2.2 EMU (Contains 1 IMX060 & 2 OV5650 sensors, in40 which only the OV5650 are supported, outputting RAW10 frames).41 42- PandaBoard, Rev.
