media: staging: drop omap4iss 

The omap4 camera driver has seen no progress since forever, and
now OMAP4 support has also been dropped from u-boot (1). So it is
time to retire this driver.

OMAP4 ISS Driver

================



Author: Sergio Aguirre <sergio.a.aguirre@gmail.com>



Copyright (C) 2012, Texas Instruments



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 [#f1]_ 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 [#f2]_, and inherited most of the

code from OMAP3 ISP driver (found under drivers/media/platform/ti/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:
