In linux kernel since version 2.6.20 (release Date: 2007-02-04)
Some EHCI chips have vendor-specific extensions to integrate
transaction translators, so that no OHCI or UHCI companion
controller is needed. It's safe to say "y" even if your
controller doesn't support this feature.
This supports the EHCI implementation that's originally
from ARC, and has since changed hands a few times.
