Subject[PATCH v3 7/8] [HACK] arm64: dts: renesas: draak: Enable LVDS
Date
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/

Thanks,
Fab
