According to what I read in the parsing 'vsps' proeprties parsing routine rcar_du_vsps_init(), if the channel index is not specified, it is defaulted to 0. /* Store the VSP pointer and pipe index in the CRTC. */ rcdu->crtcs[i].vsp = &rcdu->vsps[j]; rcdu->crtcs[i].vsp_pipe = cells >= 1 ? args.args[0] : 0; The DU bindings documentation does not state that the channel index is optional, so yes, it might be worth changing this and simplify the parsing routing to always assume the channel index is there. What does Laurent think? Is this worth the effort?

Is this worth the effort? I think it's worth the effort to keep the upstream DT sources in sync with the latest bindings, but We can't change the code as we need to ensure backward compatibility. So, yes to the DT update, but the driver should stay unmodified (or should receive a new comment explaining the required backward compatibility if there's not one already).
