Subject: [PATCH 09/19] usbnet: smsc95xx: Connect to phydev
Date: Thu,  3 Jan 2019 02:10:30 +0100	[thread overview]
Message-ID: <20190103011040.25974-10-marex@denx.de> (raw)
In-Reply-To: <20190103011040.25974-1-marex@denx.de>

Add code to detect and connect to PHY. The internal PHY of the SMSC95xx
is a regular SMSC LAN8700 and the driver only supports the internal PHY,
so just use the SMSC PHY driver to configure the PHY. Note that the
driver does a lot of extra configuration of the PHY, which is left in
to avoid breakage. Some of the extra configuration is sorted out by
later patches in this series.
