+Subject: [PATCH] net: bgmac: connect to PHY even if it is BGMAC_PHY_NOREGS
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Recent bgmac change was meant to just fix a race between "Generic PHY"
+and "bcm53xx" drivers after -EPROBE_DEFER. It modified bgmac to use
+phy_connect() only if there is a real PHY device connected.
+
+That change broke bgmac on bcm47xx. bcma_phy_connect() now registers a
+fixed PHY with the bgmac_phy_connect_direct(). That fails as another
+fixed PHY (also using address 0) is already registered - by bcm47xx arch
+code bcm47xx_register_bus_complete().
+
+This change brings origial behaviour. It connects Ethernet interface
+with pseudo-PHY (switch device) and adjusts Ethernet interface link to
+match connected switch.
+
+This fixes:
+[    2.548098] bgmac_bcma bcma0:1: Failed to register fixed PHY device
+[    2.554584] bgmac_bcma bcma0:1: Cannot connect to phy
+
+Fixes: b5375509184d ("net: bgmac: improve handling PHY")
