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... -- Rui Paulo
