Subject: [4.5-rc7+ regression, bisected] libphy: PHY stmmac-0:ffffffff not found
Date: Tue, 8 Mar 2016 19:06:23 +0100 [thread overview]
Message-ID: <56DF149F.6090100@googlemail.com> (raw)
commit 88f8b1bb41c6208f81b6a480244533ded7b59493
Author: Gabriel Fernandez <gabriel.fernandez@linaro.org>

stmmac: Fix 'eth0: No PHY found' regression
This patch manages the case when you have an Ethernet MAC with
a "fixed link", and not connected to a normal MDIO-managed PHY device.
The test of phy_bus_name was not helpful because it was never affected
and replaced by the mdio test node.
