My experience with the device tree from last time (a LED driver) was
that implementation specific properties are not that popular. A property
that tells one special driver from which speed on it should just ignore
the speed and try it's best to do max speed seems quite implementation
specific. Maybe except if I try to introduce a max-speed property to the
SPI slaves that can be used instead of the speed.
