77 At the capture and mem-to-mem video nodes only the multi-planar API is
78 supported. For more details see: :ref:`planar-apis`.
83 Each FIMC instance exports a sub-device node (/dev/v4l-subdev?), a sub-device
85 MIPI-CSI receiver device (currently up to two).
90 In order to enable more precise camera pipeline control through the sub-device
91 API the driver creates a sysfs entry associated with "s5p-fimc-md" platform
92 device. The entry path is: /sys/platform/devices/s5p-fimc-md/subdev_conf_mode.
