This is good, but I always wished some information was present on dmesg.  This could be added to the FDT and printed automatically, e.g.:

i2c1 { 
	location = "SDA header P9 pin 18, SCL header P9 pin 17";
};

That would print:

ti_i2c1: SDA header P9 pin 18, SCL header P9 pin 17

If we don't want to put this in the kernel, we could at least put it in a man page.  However, a lot of embedded systems don't even have man pages...
