13 The OMAP44XX family of chips contains the Imaging SubSystem (a.k.a. ISS),
14 Which contains several components that can be categorized in 3 big groups:
16 - Interfaces (2 Interfaces: CSI2-A & CSI2-B/CCP2)
17 - ISP (Image Signal Processor)
18 - SIMCOP (Still Image Coprocessor)
20 For more information, please look in [#f1]_ for latest version of:
21 "OMAP4430 Multimedia Device Silicon Revision 2.x"
23 As of Revision AB, the ISS is described in detail in section 8.
25 This driver is supporting **only** the CSI2-A/B interfaces for now.
27 It makes use of the Media Controller framework [#f2]_, and inherited most of the
28 code from OMAP3 ISP driver (found under drivers/media/platform/omap3isp/\*),
29 except that it doesn't need an IOMMU now for ISS buffers memory mapping.
31 Supports usage of MMAP buffers only (for now).
36 - OMAP4430SDP, w/ ES2.1 GP & SEVM4430-CAM-V1-0 (Contains IMX060 & OV5640, in
37 which only the last one is supported, outputting YUV422 frames).
39 - TI Blaze MDP, w/ OMAP4430 ES2.2 EMU (Contains 1 IMX060 & 2 OV5650 sensors, in
40 which only the OV5650 are supported, outputting RAW10 frames).
