Subject: [RESEND][PATCH 1/2] dt-bindings: usb: add non-removable-ports hub property
Date:   Fri, 24 Jan 2020 15:25:03 +0000

Add a non-removable-ports property that lists the hardwired downstream
ports of a hub.  Although hubs can provide this information, they are
not always configured correctly.  An alternate means of indicating this
for built-in USB devices is thus useful.
