Patch 8/14 adds dt-binding for PXL2DPI. An example for the PXL2DPI instance in 'mipi_lvds_0' subsystem is provided there. It doesn't make too much sense to provide examples for both 'mipi_lvds_0' subsystem and 'mipi_lvds_1' subsystem, IMHO. I think it's common that people usually provide an example for one hardware instance.
