+Date: Fri, 20 Dec 2013 02:16:06 +0100
+Subject: [PATCH 201/208] b44: check register instead of PHY address to detect
+ external PHY
 
+The Ethernet core supported by b44 supports an internal PHY integrated
+into the mac core, which is supported by the b44 driver and an external
+PHY to which the mac core is connected. This external PHY could be a
+switch connected through MII, which is often the case when this core is
+used on home routers. The usage of an external PHY was assumed when the
+PHY address 30 was used and an internal PHY was assumed when the PHY
+address was different. To verify that b44_phy_reset() was called and
+checked if it worked, otherwise PHY address 30 was assumed, an external
+PHY. It is better to check the register which says which PHY is
+connected to the MAC instead of checking the PHY address.
+The interface to an external PHY was only activated when this register
+was set.
+
+This also changes B44_FLAG_INTERNAL_PHY to B44_FLAG_EXTERNAL_PHY, it is
+easier to check.

 When the phy address is 31, this means that there is no PHY connected
 to this MAC at all, no internal and no external PHY. Reading these PHY
 registers causes a system reset on some routers.

 rename the old ones before. This now indicates that these functions are
 used for the mdio registers and on the mii interface.

+If the internal PHY is not used, b44 will now search on the MDIO bus
+for a phy and use the Linux phylib subsystem to register a driver.
+Support for the internal PHY must stay here, because there are some
+device which are suing the internal phy.
+
 With this patch we scan the mdio bus when the sprom or nvram says that
 the PHY address is 30, if a PHY was found at this address b44 uses it.
 
 This was tested with a BCM4704, BCM4712 and BCM5354.

+Subject: [PATCH 207/208] b44: do not set PHY address to 30 for every ext PHY
+
+b44_phy_reset() will fail for an external PHY and only work with the
+internal PHY, this was an old workaround when the detection of an
+external switch based on the PHY address failed and it is not needed
+any more.

+Subject: [PATCH 208/208] b44: use fixed PHY device if we do not find any
+
+The ADM6996L switch and some Broadcom switches with two MII interfaces
+like the BCM5325F connected to two MACs on the SoC, used on some
+routers do not return a valid value when reading the PHY id register
+and Linux thinks there is no PHY at all, but that is wrong.
+This patch registers a fixed phy in the arch code and then searches it
+when there is no other phy in the Ethernet driver code.
