We set in omap_dsihw_probe:

static int __init omap_dsihw_probe(struct platform_device *dsidev)
{
	...
	...
         /* DSI VCs initialization */
         for (i = 0; i < ARRAY_SIZE(dsi->vc); i++) {
                 dsi->vc[i].source = DSI_VC_SOURCE_L4;
                 dsi->vc[i].dssdev = NULL;
                 dsi->vc[i].vc_id = 0;
         }
	...
	...
}
