Hi all,

this is a v3, which has only a minor change in a second patch.

The LVDS differential voltage swing can be 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.

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. Please apply the dependent series first before
applying this one.

v1 is at: https://lore.kernel.org/all/20241127103031.1007893-1-andrej.picej@norik.com/
v2 is at: https://lore.kernel.org/all/20241203085822.2475138-1-andrej.picej@norik.com/
