These are self-extracting shell scripts with an attached compressed tar archive. This particular file can be extracted by skipping the first 34087 bytes: dd if=firmware-imx-5.4.bin bs=34087 skip=1 | tar xjv > (Maybe it'd be worth adding some short documentation on this.

I'm not sure the device tree binding docs are the right place to document driver and firmware though. For that, adding a coda.rst entry to Documentation/media/v4l-drivers would probably be a better place. regards Philipp
