The d_can0/1 module integrated with AM335x device, requires only one clock (fck) and driver expects clock to be available without specifying any connection id (con_id) - clk_get(&pdev->dev, NULL); This is acceptable as module has only one clock and platform code should respect this request, so create new clock nodes inside am33xx clock-tree table based on dev_id and "con_id = NULL" for both d_can0 and d_can1 instances.
