Subject: [usb-next PATCH v11 8/8] usb: core: hcd: remove support for initializing a single PHY
Date: Sat,  3 Mar 2018 22:43:09 +0100	[thread overview]
Message-ID: <20180303214309.25643-9-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20180303214309.25643-1-martin.blumenstingl@googlemail.com>

With the new PHY wrapper in place we can now handle multiple PHYs.
Remove the code which handles only one generic PHY as this is now
covered (with support for multiple PHYs as well as suspend/resume
support) by the new PHY wrapper.
