As LVDS 0 is the fourth channel (DU3), should it be listed under port 3
instead of port 2?
I know we did it the same for R-Car M3-N and RZ/G2N.
But my main worry is adding support for R-Car H3-N later.

I do agree too, with the below diff I tested the LVDS output on RZ/G2N
Rev2 board and things work fine. But only thing it doesn't explain is
why does LVDS work on DU2 for G2[H/N] boards :D

Why should we do so ? The port number here isn't tied to the DU channel
number. It only identifies the output port. Many DUs can route DU
channel outputs to different output ports.

The binding document (renesas,du.txt) does state that "The following
table lists for each supported model the port number corresponding to
each DU output.", hence the confusion.

It can be a bit confusing indeed. "DU output" here refers to the output
of the whoel DU, made of individual DU channels. Each DU channel is
listed as a DU device in the datasheet, and collectively they are the DU
device that Linux handles.

The LVDS encoder on RZ/G2H (R8A774E1) SoC is identical to R-Car Gen3 so
just reuse the rcar_lvds_gen3_info structure to hookup R8A774E1 to LVDS
encoder driver.
