From ffe95371d2a84f3ad8085656d4fcb2fc926ff7a1 Mon Sep 17 00:00:00 2001 From: Mathias Nyman Date: Thu, 19 Apr 2018 19:05:50 +0300 Subject: usb: define HCD_USB32 speed option for hosts that support USB 3.2 dual-lane Hosts that support USB 3.2 Enhaned SuperSpeed can set their hcd speed to HCD_USB32 to let usb core and host drivers know that the controller supports new USB 3.2 dual-lane features. make sure usb core handle HCD_USB32 hosts correctly, for now similar to HCD_USB32.
