Yes. So how if the dt  looks like this

usb {
         ....
         ....
         usb_ctrl_mod {
             ....
             ....
         };
         usb0 {
             ....
             ....
         };
         usb0_phy {
             ....
             ....
         };
         usb1 {
             ....
             ....
         };
         usb1_phy {
             ....
             ....
         };

         cppi41dma {
             ....
             ....
         };
};
