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:
