This also merges exynos5-fimc-is and exynos-mdevice into single
kernel module called exynos-iss.ko.

[media] Add driver for exynos5 FIMC-IS subsystem
This driver is for the FIMC-IS IP available in Samsung Exynos5
SoC onwards.
exynos5-fimc-is: Add common driver header files
This patch adds all the common header files used by the fimc-is
driver. It includes the commands for interfacing with the firmware
and error codes from IS firmware, metadata and command parameter
definitions.
exynos5-fimc-is: Add register definition and context header
This patch adds the register definition file for the fimc-is driver
and also the header file containing the main context for the driver.
exynos5-fimc-is: Add isp subdev
fimc-is driver takes video data input from the ISP video node
which is added in this patch. This node accepts Bayer input
buffers which is given from the IS sensors.
exynos5-fimc-is: Add scaler subdev
FIMC-IS has two hardware scalers named as scaler-codec and
scaler-preview. This patch adds the common code handling the
video nodes and subdevs of both the scalers.
exynos5-fimc-is: Add sensor interface
Some sensors to be used with fimc-is are exclusively controlled
by the fimc-is firmware. This minimal sensor driver provides
the required info for the firmware to configure the sensors
sitting on I2C bus.
exynos5-fimc-is: Add the hardware pipeline control
This patch adds the crucial hardware pipeline control for the
fimc-is driver. All the subdev nodes will call this pipeline
interfaces to reach the hardware. Responsibilities of this module
involves configuring and maintaining the hardware pipeline involving
multiple sub-ips like ISP, DRC, Scalers, ODC, 3DNR, FD etc.
exynos5-fimc-is: Add the hardware interface module
The hardware interface module finally sends the commands to the
FIMC-IS firmware and runs the interrupt handler for getting the
responses.

exynos5-is: Add media device driver for exynos5 SoCs camera subsystem
This patch adds a top level media device driver for the Exynos5 SoC series
camera subsystem. The driver currently supports processing pipelines
involving following IP blocks:
* MIPI-CSIS
MIPI CSI-2 bus front-end to the FIMC-LITE, image sensors with MIPI CSI-2
bus should be linked with FIMC-LITE through this sub-device.
* FIMC-LITE
Supports capture interface from device (Sensor, MIPI-CSIS) to memory.
Supports interconnection (through internal data FIFO links) between
devices like MIPI-CSIS and FIMC-IS.
* FIMC-IS
Camera ISP with multiple image processing and peripheral devices like
I2C or SPI bus controllers.
The G-Scaler IP is not yet supported.
The media device creates two kinds of pipelines for connecting the above
mentioned IP blocks.
The pipeline0 contains Sensor, MIPI-CSIS and FIMC-LITE devices and allows
to capture image data from external sensor to memory.
Pipeline1 uses FIMC-IS components for image processing operations on the
captured raw image data and provides scaled YUV image data at its output.
