OMAP4 ISS Driver
================
Author: Sergio Aguirre <sergio.a.aguirre@gmail.com>
Copyright (C) 2012, Texas Instruments
[media] v4l: omap4iss: Add support for OMAP4 camera interface - Core This adds a very simplistic driver to utilize the CSI2A interface inside the ISS subsystem in OMAP4, and dump the data to memory. Check Documentation/video4linux/omap4_camera.txt for details. This commit adds the driver core, registers definitions and documentation.

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)

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:
