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.
