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 {=20
	location =3D "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...
