+- Clean up and move the ov5642 subdev driver to drivers/media/i2c, or
+ merge support for OV5642 into drivers/media/i2c/ov5640.c, and create
+ the binding docs for it.
+
+- The Frame Interval Monitor could be exported to v4l2-core for
+ general use.
+
+- At driver load time, the device-tree node that is the original source
+ (the "sensor"), is parsed to record its media bus configuration, and
+ this info is required in imx-media-csi.c to setup the CSI.
+ Laurent Pinchart argues that instead the CSI subdev should call its
+ neighbor's g_mbus_config op (which should be propagated if necessary)
+ to get this info. However Hans Verkuil is planning to remove the
+ g_mbus_config op. For now this driver uses the parsed DT mbus config
+ method until this issue is resolved.
+
+- This media driver supports inheriting V4L2 controls to the
+ video capture devices, from the subdevices in the capture device's
+ pipeline. The controls for each capture device are updated in the
+ link_notify callback when the pipeline is modified. It should be
+ decided whether this feature is useful enough to make it generally
+ available by exporting to v4l2-core.
