+Samsung S5P/EXYNOS4 FIMC driver
+
+Copyright (C) 2012 Samsung Electronics Co., Ltd.
+---------------------------------------------------------------------------
+
+The FIMC (Fully Interactive Mobile Camera) device available in Samsung
+SoC Application Processors is an integrated camera host interface, color
+space converter, image resizer and rotator. It's also capable of capturing
+data from LCD controller (FIMD) through the SoC internal writeback data
+path. There are multiple FIMC instances in the SoCs (up to 4), having
+slightly different capabilities, like pixel alignment constraints, rotator
+availability, LCD writeback support, etc. The driver is located at
+drivers/media/video/s5p-fimc directory.
+
+1. Supported SoCs
+=================
+
+S5PC100 (mem-to-mem only), S5PV210, EXYNOS4210
+
+2. Supported features
+=====================
+
+ - camera parallel interface capture (ITU-R.BT601/565);
+ - camera serial interface capture (MIPI-CSI2);
+ - memory-to-memory processing (color space conversion, scaling, mirror
+ and rotation);
+ - dynamic pipeline re-configuration at runtime (re-attachment of any FIMC
+ instance to any parallel video input or any MIPI-CSI front-end);
+ - runtime PM and system wide suspend/resume
+
+Not currently supported:
+ - LCD writeback input
+ - per frame clock gating (mem-to-mem)
+
+3. Files partitioning

+ drivers/media/video/s5p-fimc/regs-fimc.h
+
+4. User space interfaces
+========================
+
+4.1. Media device interface
+
+The driver supports Media Controller API as defined at
+http://http://linuxtv.org/downloads/v4l-dvb-apis/media_common.html
+The media device driver name is "SAMSUNG S5P FIMC".
+
+The purpose of this interface is to allow changing assignment of FIMC instances
+to the SoC peripheral camera input at runtime and optionally to control internal
+connections of the MIPI-CSIS device(s) to the FIMC entities.
+
+The media device interface allows to configure the SoC for capturing image
+data from the sensor through more than one FIMC instance (e.g. for simultaneous
+viewfinder and still capture setup).
+Reconfiguration is done by enabling/disabling media links created by the driver
+during initialization. The internal device topology can be easily discovered
+through media entity and links enumeration.
+
+4.2. Memory-to-memory video node
+
+V4L2 memory-to-memory interface at /dev/video? device node. This is standalone
+video device, it has no media pads. However please note the mem-to-mem and
+capture video node operation on same FIMC instance is not allowed. The driver
+detects such cases but the applications should prevent them to avoid an
+undefined behaviour.
+
+4.3. Capture video node
+
+The driver supports V4L2 Video Capture Interface as defined at:
+http://linuxtv.org/downloads/v4l-dvb-apis/devices.html
+
+At the capture and mem-to-mem video nodes only the multi-planar API is
+supported. For more details see:
+http://linuxtv.org/downloads/v4l-dvb-apis/planar-apis.html
+
+4.4. Camera capture subdevs
+
+Each FIMC instance exports a sub-device node (/dev/v4l-subdev?), a sub-device
+node is also created per each available and enabled at the platform level
+MIPI-CSI receiver device (currently up to two).
+
+4.5. sysfs
+
+In order to enable more precise camera pipeline control through the sub-device
+API the driver creates a sysfs entry associated with "s5p-fimc-md" platform
+device. The entry path is: /sys/platform/devices/s5p-fimc-md/subdev_conf_mode.
+
+In typical use case there could be a following capture pipeline configuration:
+sensor subdev -> mipi-csi subdev -> fimc subdev -> video node
+
+When we configure these devices through sub-device API at user space, the
+configuration flow must be from left to right, and the video node is
+configured as last one.
+When we don't use sub-device user space API the whole configuration of all
+devices belonging to the pipeline is done at the video node driver.
+The sysfs entry allows to instruct the capture node driver not to configure
+the sub-devices (format, crop), to avoid resetting the subdevs' configuration
+when the last configuration steps at the video node is performed.
+
+For full sub-device control support (subdevs configured at user space before
+starting streaming):
+# echo "sub-dev" > /sys/platform/devices/s5p-fimc-md/subdev_conf_mode
+
+For V4L2 video node control only (subdevs configured internally by the host
+driver):
+# echo "vid-dev" > /sys/platform/devices/s5p-fimc-md/subdev_conf_mode
+This is a default option.
+
+5. Device mapping to video and subdev device nodes
+==================================================
+
+There are associated two video device nodes with each device instance in
+hardware - video capture and mem-to-mem and additionally a subdev node for
+more precise FIMC capture subsystem control. In addition a separate v4l2
+sub-device node is created per each MIPI-CSIS device.
+
+How to find out which /dev/video? or /dev/v4l-subdev? is assigned to which
+device?
+
+You can either grep through the kernel log to find relevant information, i.e.
+# dmesg | grep -i fimc
+(note that udev, if present, might still have rearranged the video nodes),
+
+or retrieve the information from /dev/media? with help of the media-ctl tool:
+# media-ctl -p
+
+6. Platform support
+===================
+
+The machine code (plat-s5p and arch/arm/mach-*) must select following options
+
+CONFIG_S5P_DEV_FIMC0 mandatory
+CONFIG_S5P_DEV_FIMC1 \
+CONFIG_S5P_DEV_FIMC2 | optional
+CONFIG_S5P_DEV_FIMC3 |
+CONFIG_S5P_SETUP_FIMC /
+CONFIG_S5P_SETUP_MIPIPHY \
+CONFIG_S5P_DEV_CSIS0 | optional for MIPI-CSI interface
+CONFIG_S5P_DEV_CSIS1 /
+
+Except that, relevant s5p_device_fimc? should be registered in the machine code
+in addition to a "s5p-fimc-md" platform device to which the media device driver
+is bound. The "s5p-fimc-md" device instance is required even if only mem-to-mem
+operation is used.
+
+The description of sensor(s) attached to FIMC/MIPI-CSIS camera inputs should be
+passed as the "s5p-fimc-md" device platform_data. The platform data structure
+is defined in file include/media/s5p_fimc.h.
+
+7. Build
+========
+
+This driver depends on following config options:
+PLAT_S5P,
+PM_RUNTIME,
+I2C,
+REGULATOR,
+VIDEO_V4L2_SUBDEV_API,
+
+If the driver is built as a loadable kernel module (CONFIG_VIDEO_SAMSUNG_S5P_FIMC=m)
+two modules are created (in addition to the core v4l2 modules): s5p-fimc.ko and
+optional s5p-csis.ko (MIPI-CSI receiver subdev).
