Hi!
For the needs of raw image decoding libraries, and whoever else might need it, there is a repository of free (CC0) raw files.
You can read about it
here and
here.
Currently, we would love to get the raw sample set for these two cameras (Canon EOS 5DS / Canon EOS 5DSR).
Since Magic Lantern is for Canon cameras, i figured it is worth a try asking here

What samples are needed:
- The camera needs to be stable (tripod), in the landscape orientation, and the scene should be as static as possible (i.e. all the raws must contain the same content).
- There are just three samples: RAW, mRAW, sRAW.
And then just upload them to
https://raw.pixls.us/ ideally, rename them before that though
