Hi all,

this is a v2, which is quite different than the v1. The LVDS differential
voltage swing is now specified as arrays of min, max in microvolts. Two
arrays, one for data-lanes and one for clock-lane can be specified.
Additionally, because LVDS voltage swing depends on near-end termination
this can now also be specified with separate property.

Driver goes through the tables, taken from datasheet [1] and selects the
appropriate configuration. If appropriate configuration can not be found
the probe fails. If these properties are not defined default values are
used as before.

v1 is at: https://lore.kernel.org/all/20241127103031.1007893-1-andrej.picej@norik.com/
v2 changes are described in corresponding patches.
