From: Hugo Villeneuve <[email protected]> Add support for the LD configuration option (LVDS encoder assembled on SOM) so that the LVDS display panel on the concerto EVK board now works properly.
Not all VAR-SOM-6UL SOMs have the LD configuration optionso factor out this functionality to a separate DTSI file.
