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

The entire API is documented - below. In the most general case, to support a sensor there are three steps - you have to follow: - 1) define the main "sn9c102_sensor" structure by setting the basic fields; - 2) write a probing function to be called by the core module when the USB - camera is recognized, then add both the USB ids and the name of that - function to the two corresponding tables in sn9c102_devtable.h; - 3) implement the methods that you want/need (and fill the rest of the main - structure accordingly). - "sn9c102_pas106b.c" is an example of all this stuff. Remember that you do - NOT need to touch the source code of the core module for the things to work - properly, unless you find bugs or flaws in it.
