I would vastly prefer that the binding doc filenames use the compatible value exactly. All (or as many as possible) of the other Tegra bindings do this, and I think it's good style.

It didn't as far as I can tell, even though I think someone said it should... Will it make 3.9? As a general rule, I'd like to move forward on drivers and then refactor this aspect once the generic API/binding is finalized and implemented.
(I couldn't find any more comments of yours below, but since the whole patch was quoted, it was difficult to tell)
