[PATCH 21/25] thunderbolt: Update Kconfig entry to USB4

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since the driver now supports USB4 which is the standard going forward,
update the Kconfig entry to mention this and rename the entry from
CONFIG_THUNDERBOLT to CONFIG_USB4 instead to help people to find the
correct option if they want to enable USB4.

Also update Thunderbolt network driver dependency accordingly.
