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.
