1 OMAP4 ISS Driver 2 ================ 3 4 Introduction 5 ------------ 6 7 The OMAP44XX family of chips contains the Imaging SubSystem (a.k.a. ISS), 8 Which contains several components that can be categorized in 3 big groups: 9 10 - Interfaces (2 Interfaces: CSI2-A & CSI2-B/CCP2) 11 - ISP (Image Signal Processor) 12 - SIMCOP (Still Image Coprocessor) 13 14 For more information, please look in [1] for latest version of: 15 "OMAP4430 Multimedia Device Silicon Revision 2.x" 16 17 As of Revision AB, the ISS is described in detail in section 8. 18 19 This driver is supporting _only_ the CSI2-A/B interfaces for now. 20 21 It makes use of the Media Controller framework [2], and inherited most of the 22 code from OMAP3 ISP driver (found under drivers/media/platform/omap3isp/*), 23 except that it doesn't need an IOMMU now for ISS buffers memory mapping. 24 25 Supports usage of MMAP buffers only (for now). 26 27 Tested platforms 28 ---------------- 29 30 - OMAP4430SDP, w/ ES2.1 GP & SEVM4430-CAM-V1-0 (Contains IMX060 & OV5640, in 31 which only the last one is supported, outputting YUV422 frames). 32 33 - TI Blaze MDP, w/ OMAP4430 ES2.2 EMU (Contains 1 IMX060 & 2 OV5650 sensors, in 34 which only the OV5650 are supported, outputting RAW10 frames). 35 36 - PandaBoard, Rev. A2, w/ OMAP4430 ES2.1 GP & OV adapter board, tested with 37 following sensors: 38 * OV5640 39 * OV5650 40 41 - Tested on mainline kernel: 42 43 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=summary 44 45 Tag: v3.3 (commit c16fa4f2ad19908a47c63d8fa436a1178438c7e7) 46 47 File list 48 --------- 49 drivers/staging/media/omap4iss/ 50 include/linux/platform_data/media/omap4iss.h 51 52 References 53 ---------- 54 55 [1] http://focus.ti.com/general/docs/wtbu/wtbudocumentcenter.tsp?navigationId=12037&templateId=6123#62 56 [2] http://lwn.net/Articles/420485/ 57 [3] http://www.spinics.net/lists/linux-media/msg44370.html 58 -- 59 Author: Sergio Aguirre <sergio.a.aguirre@gmail.com> 60 Copyright (C) 2012, Texas Instruments
