Hi Bryan!
These commands are to set up the pipeline, and what then to grab an
image from it?
I tried this, but it also just hangs:
$ yavta -B capture-mplane --capture=3 -n 3 -f SRGGB10P -s 4056x3040 /dev/video0 --file=foo-#.bin
Device /dev/video0 opened.
Device `Qualcomm Camera Subsystem' on `platform:acb3000.camss' (driver 'qcom-camss') supports video, capture, with mplanes.
Video format set: SRGGB10P (41415270) 4056x3040 field none, 1 planes:

Stride 5072, buffer size 15418880

No there's no CSIPHY in that case, it should be the TPG inside of CSID0 
@ /dev/v4l-subdev5 which generates the data.
I understand the lack of csiphy involvement here, but how's this
relevant to reading data from /dev/video0? That's the vfe which gets
hooked up with the media-ctl commands to my understanding?
And v4l-subdev5 is msm_csid0 on my device.
...
Just for verification purposes do a  `media-ctl -d /dev/media0 -p` and 
confirm that /dev/v4l-subdev5 == csid0
Rewrite the above as
export csid0=v4l-subdevX
media-ctl --reset
yavta --no-query -w '0x009f0903 2' /dev/$csid0
yavta --list /dev/$csid0
media-ctl -V '"msm_csid0":0[fmt:SRGGB10/4056x3040]'
media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/4056x3040]'
media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
media-ctl -d /dev/media0 -p
basically you have to make sure you've set the TPG on the correct subdev..
Something like in media-ctl subdev4 in my case.

entity 13: msm_csid0 (5 pads, 36 links, 0 routes)
            type V4L2 subdev subtype Unknown flags 0
            device node name /dev/v4l-subdev4

Sure, here's the output from the commands:
fairphone-fp5:~$ export csid0=v4l-subdev5
fairphone-fp5:~$ media-ctl --reset
fairphone-fp5:~$ yavta --no-query -w '0x009f0903 2' /dev/$csid0
