[PATCH 1/2] dt-bindings: usb-ehci: Add an optional property "needs-reset-on-resume"

From: Wu Liang feng
Date: Wed Dec 24 2014 - 05:23:13 EST


Add device-tree bindings for EHCI so we can use "needs-reset-on-resume"
property to force EHCI reset after resume if necessary. This is necessary
on platforms like rk3288 that need a reset after resume to detect if a
device has been disconnected during suspend time.
