[PATCH v2 1/2]: Add an optional property "needs-reset-on-resume"
in usb-ehci dt-bingdings.
[PATCH v2 2/2]: modify ehci-platform driver to support ehci reset
after resume quirk if necessary.
Wu Liang feng (2):
dt-bindings: usb-ehci: Add an optiona
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.

rename the "hibernation" paramter of
ehci_resume() to force_reset since hibernation is simply
another case where we can't trust the autodetected status
and need to force a reset of devices.
