Sorry, I didn't notice that comment in your email, since the quoting 
style wasn't standard (indent with >).

It's the responsibility of the person who implements the driver for the 
device. Writing binding docs is now unfortunately part and parcel of 
almost any driver work.

This device is probably similar enough to the other Tegra SPI 
controllers that you can likely cut/paste most of the doc, and simply 
adjust the names and resource definitions as appropriate for this HW module.
