Subject: [PATCH 3.2 007/147] usb: renesas_usbhs: fixup resume method for
 autonomy mode

3.2.95-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Kuninori Morimoto <kuninori.morimoto.gx@...esas.com>

commit 5b50d3b52601651ef3183cfb33d03cf486180e48 upstream.

If renesas_usbhs is probed as autonomy mode,
phy reset should be called after power resumed,
and manual cold-plug should be called with slight delay.
