For all TI platforms handled in this series, USBx dr_mode was configured as peripheral in '<board>-u-boot.dtsi'. This series removes these fragments, since USBx dual-role feature is already handled as peripheral only in 'dwc3_glue_bind_common()' function of 'dwc3-generic.c' driver:
static int dwc3_glue_bind_common(struct udevice *parent, ofnode node) { [...]
switch (dr_mode) { case USB_DR_MODE_PERIPHERAL: case USB_DR_MODE_OTG:
debug("%s: dr_mode: OTG or Peripheral\n", __func__); driver = "dwc3-generic-peripheral";
break;
[...] }
This follows a discussion about a similar topic for am3 boards: https://lore.kernel.org/u-boot/20230621-fix_usb_ether_init-v4-0-5f4977bb7678...
