Mentioning J6 should be in there, but feel free to ignore the other two comments.
Unrelated, but rereading that page has also made me note that https://www.raspberrypi.com/documentation/computers/compute-module.html#connect-one-camera says dtoverlay=ov5647,cam1 etc.
There is no cam1 override, only cam0. Using cam1 is the default, and the firmware will be logging that cam1 is an unknown override.

| Touch Display 2 is a 720x1280 7" LCD display designed specifically for Raspberry Pi devices (see https://www.raspberrypi.com/products/touch-display-2/). It connects in the same way as the original touch display, but the software setup on Compute Modules is slightly different as it uses a different display driver. See xref:../accessories/touch-display-2.adoc[Touch Display 2] for connection details. | ||

| Edit the /boot/firmware/config.txt file and add the following to enable Touch Display 2 on DISP1/DSI1. You will also need to add jumpers to J6 as indicated on the silkscreen. |

Looking at the earlier TD1 instructions, is this J6 jumper specific to CM4 IO board? 🤔

CM4IO J6 connects I2C to CAM0 and DISP0
CM5IO J6 connects I2C to CAM/DISP1.
No comment on consistency!

(and we probably also want CM 1 / 3 / 4S hookup instructions for TD2?)

Are the jumper settings etc. identical for TD1 and TD2? In which case perhaps the "You will also need to add jumpers to J6 as indicated on the silkscreen." phrase here should be removed, and replaced with something like "See the earlier Touch Display instructions for details of required jumper settings." ?
Or (as a bigger change) perhaps it worth separating out the electrical-hookup instructions (jumpers etc.) which are the same for both TD1 and TD2, from the config.txt instructions which are different for TD1 and TD2? 🤔

Yes. It's a board level thing, not what display is connected.
Remove unnecessary `cam1` directives, as detailed in #4084 (review)
Supercedes #4072
