Some board designs do not drive the SATA transmit lines within the
specification. The ECME can provide override settings, on a per board
basis, to bring the transmit lines within spec. Read those settings
from the DTB and program them in.

How variable is the use of this property going to be? Would it instead
be possible to decide that this was necessary, and choose the
appropriate values based on a compatible property?

It is based on compliance testing of the particular board design. Basing
on a compatible property would not work in this case.

Ok. Could you clarify the u8/cell usage in the binding and amend the
example please?

Cheers,
Mark.
