Bigtreetech raspberry pad 5 touch not working with new CM5

I have managed to put a CM 5 into the raspberry pad 5 and everything works except the touch screen. I guess the old blobin does not work with the new CM5 has someone solved this?

Any use of dt-blob.bin would imply that they are also trying to use the legacy camera or display stacks. Those simply do not exist on Pi5 / CM5, so trying to use it will fail.

The vc4-kms-v3d kernel drivers have been the standard for several years, so applications have had time to switch over.
CM5 does not support autodetection of displays, so has to be manually configured with dtoverlay=v4-kms-dsi-7inch (assuming default GPIO and I2C assignments - the manual implies it does as it says to use dt-blob-disp1-cam1.bin).

Then again the manual says that the touch controller is a GT911, so that isn't going to work with the firmware (expects an EDT FT5406). THey may have done the same as a few other manufacturers and put a microcontroller on the board to do protocol conversion between GT911 and FT5406.

I was going to say raise an issue on their Github, but someone already has - bigtreetech/Raspberry-Pad#22, but no response since January.
