Do the Renesas and TI controllers still advertise the extended capability
for the handoff? (XHCI_EXT_CAPS_LEGACY)
Is this some known issue with these vendors controllers? Is there some documentation
about this, errata or anything?
Adding Yoshihiro Shimoda, he might know about the Renesas controller.
