The platform I'm working on has a different method of muxing for almost 
every pin (some aren't even memory mapped registers) so defining the SoC 
pin definitions in the DTS could result in some pretty horrible 
bindings.

Stephens bindings for configuring the muxing of the pins works quite 
nicely for our platform though, and I'm just about to post patches that 
abstract the tegra specific bits out.
