+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 [#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
