I believe this is caused by the missing orientation property in the
device tree. The ov5640 driver from mainline calls
v4l2_fwnode_device_parse(), which should create the rotation control
when the device tree property is present. Could you test that ? It would
then be nice to upstream a patch to add the ov5640 to the pinephone
device tree.

It's not about the sensor, it's about the video device side. If I'm not
mistaken, on the pinephone, that would be the sun6i-csi driver. The
driver needs to implement V4L2_CAP_IO_MC, and in particular, update the
.vidioc_enum_fmt_vid_cap() handler accordingly. See
https://docs.kernel.org/userspace-api/media/v4l/vidioc-enum-fmt.html.
