Enable and connect the second LVDS encoder to the second LVDS input of the THC63LVD1024 for dual-link LVDS operation. This requires changing the default settings of SW45 and SW47 to OFF and ON respectively.
This patch is based on Laurent's dual-LVDS work: https://patchwork.kernel.org/patch/10965045/ Signed-off-by: Fabrizio Castro <fabrizio.cas...@bp.renesas.com> --- v2->v3: * new patch Geert, no need to review this patch unless they like the idea behind this series.
