Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:
 - a new jpeg codec driver for Samsung Exynos (jpeg-hw-exynos4)
 - a new dvb frontend for ds2103 chipset (m88ds2103)
 - a new sensor driver for Samsung S5K5BAF UXGA (s5k5baf)
 - new drivers for R-Car VSP1
 - a new radio driver: radio-raremono
 - a new tuner driver for ts2022 chipset (m88ts2022)
 - the analog part of em28xx is now a separate module that only
   load/runs if the device is not a pure digital TV device
 - added a staging driver for bcm2048 radio devices
 - the omap 2 video driver (omap24xx) was moved to staging.  This driver
   is for an old hardware and uses a deprecated Kernel internal API.  If
   nobody cares enough to fix it, it would be removed on a couple Kernel
   releases
 - the sn9c102 driver was moved to staging.  This driver was replaced by
   gspca, and disabled on some distros, as almost all devices are known
   to work properly with gspca.  It should be removed from kernel on a
   couple Kernel releases
 - lots of driver fixes, improvements and cleanups

+                              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:
+
+	http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=summary
+
+  Tag: v3.3 (commit c16fa4f2ad19908a47c63d8fa436a1178438c7e7)
