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?
Thanks
