Is the timeout really a /software/ property?  My feeling is that the timeou=
t basically depends upon the bus clock and the chips attached to the bus.  =
Therefore, it is linked closer to the composition of the board's hardware a=
s described in the device tree, than to any userland software.  Or am I tot=
ally wrong here?

Thanks, Albrecht.
