Add properties which can be used to specify LVDS differential output voltage. Since this also depends on near-end signal termination also include property which sets this. LVDS differential output voltage is specified with an array (min, max), which should match the one from connected device. Signed-off-by: Andrej Picej <andrej.picej@norik.com> --- Changes in v3: - no change Changes in v2: - move LVDS port schema to a $defs and reference it from there - properties are now defined in microvolts/ohms - use 1 property for data-lane and 1 for clock-lane LVDS voltage swing - add 1 property which sets LVDS near-end termination - since major change was done change the authorship to myself --- .../bindings/display/bridge/ti,sn65dsi83.yaml | 36 +++++++++++++++++-- 1 file changed, 33 insertions(+), 3 deletions(-)
