I also see other boards doing the wrong thing. i.e. replacing 'otg' with 'peripheral'.

dra71-evm-u-boot.dtsi:	dr_mode = "peripheral";
dra72-evm-revc-u-boot.dtsi:	dr_mode = "peripheral";
dra72-evm-u-boot.dtsi:	dr_mode = "peripheral";
dra76-evm-u-boot.dtsi:	dr_mode = "peripheral";
dra7-evm-u-boot.dtsi:	dr_mode = "peripheral";
k3-am642-evm-u-boot.dtsi:	dr_mode="peripheral";
k3-am654-r5-base-board-u-boot.dtsi:	dr_mode = "peripheral";
k3-am654-r5-base-board-u-boot.dtsi:	dr_mode = "peripheral";
k3-j7200-common-proc-board-u-boot.dtsi:	dr_mode = "peripheral";
k3-j721e-common-proc-board-u-boot.dtsi:	dr_mode = "peripheral";
keystone-k2e-evm-u-boot.dtsi:		dr_mode = "peripheral";

Is this something you can fix (in dwc3 driver) as it is on similar lines ;). Thanks!
