Hi Andrzej,

The of_graph_get_remote_node() does not exist in the kernel.
Also this patch  does not apply('git am') on drm-next tree.
Is this what you mean?
         dsi->bridge_node = of_graph_get_endpoint_by_regs(node, 
DSI_PORT_IN, 0);
         if (!dsi->bridge_node)
                 return -EINVAL;

Best regards,
Hoegeun
