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. This patch series depends on the patch "[PATCH v2 11/15] arm64: dts: imx8mm-phyboard-polis: Add support for PEB-AV-10" (https://lore.kernel.org/all/20241202072052.2195283-12-andrej.picej@norik.com/) which is currently under review.
