| OMAP4 ISS Driver | |
| ================ | |
| Introduction | |
| ------------ | |
| The OMAP44XX family of chips contains the Imaging SubSystem (a.k.a. ISS), | |
| Which contains several components that can be categorized in 3 big groups: | |
| - Interfaces (2 Interfaces: CSI2-A & CSI2-B/CCP2) | |
| - ISP (Image Signal Processor) | |
| - SIMCOP (Still Image Coprocessor) | |
| For more information, please look in [1] for latest version of: | |
| "OMAP4430 Multimedia Device Silicon Revision 2.x" | |
| As of Revision AB, the ISS is described in detail in section 8. | |
| This driver is supporting _only_ the CSI2-A/B interfaces for now. | |
| It makes use of the Media Controller framework [2], and inherited most of the | |
| code from OMAP3 ISP driver (found under drivers/media/platform/omap3isp/*), | |
| except that it doesn't need an IOMMU now for ISS buffers memory mapping. | |
| Supports usage of MMAP buffers only (for now). | |
| Tested platforms | |
| ---------------- | |
| - OMAP4430SDP, w/ ES2.1 GP & SEVM4430-CAM-V1-0 (Contains IMX060 & OV5640, in | |
| which only the last one is supported, outputting YUV422 frames). | |
| - TI Blaze MDP, w/ OMAP4430 ES2.2 EMU (Contains 1 IMX060 & 2 OV5650 sensors, in | |
| which only the OV5650 are supported, outputting RAW10 frames). | |
| - PandaBoard, Rev. A2, w/ OMAP4430 ES2.1 GP & OV adapter board, tested with | |
| following sensors: | |
| * OV5640 | |
| * OV5650 | |
| - Tested on mainline kernel: | |
