Could it be that the "Gen3" values are specific to the H3 ES1.x ? I've got the

I don't know. All I know is that the LVDCR1 description was changed in v.52 of the gen3 manual (the 1st version that documented R-Car V3M).

LVDS output working on a Salvator-X H3 board with the existing code, although
I'm not sure at the moment whether that was on ES1.x or ES2.0. I can check

On which platform have you tested this patch ?

   R-Car V3M (R8A77970), V3M Starter Kit board.
