+Subject: mtd: nand: Warn the user if the selected ECC strength is too weak
+
+This commit makes use of the chip->ecc_strength_ds and chip->ecc_step_ds which
+contain the datasheet minimum requested ECC strength to produce a noisy warning
+if the configured ECC strength is weaker.

+Subject: net: phy: decouple PHY id and PHY address in fixed PHY driver
+
+Until now, the fixed_phy_add() function was taking as argument
+'phy_id', which was used both as the PHY address on the fake fixed
+MDIO bus, and as the PHY id, as available in the MII_PHYSID1 and
+MII_PHYSID2 registers. However, those two informations are completely
+unrelated.
+
+This patch decouples them. The PHY id of fixed PHYs is hardcoded to be
+0x0. Ideally, a really reserved value would be nicer, but there
+doesn't seem to be an easy of making sure a dummy value can be
+assigned to the Linux kernel for such usage.
+
+The PHY address remains passed by the caller of phy_fixed_add().

+Subject: net: phy: extend fixed driver with fixed_phy_register()
+
+The existing fixed_phy_add() function has several drawbacks that
+prevents it from being used as is for OF-based declaration of fixed
+PHYs:
+
+ * The address of the PHY on the fake bus needs to be passed, while a
+   dynamic allocation is desired.
+
+ * Since the phy_device instantiation is post-poned until the next
+   mdiobus scan, there is no way to associate the fixed PHY with its
+   OF node, which later prevents of_phy_connect() from finding this
+   fixed PHY from a given OF node.
+
+To solve this, this commit introduces fixed_phy_register(), which will
+allocate an available PHY address, add the PHY using fixed_phy_add()
+and instantiate the phy_device structure associated with the provided
+OF node.

+Subject: of: provide a binding for fixed link PHYs
+
+Some Ethernet MACs have a "fixed link", and are not connected to a
+normal MDIO-managed PHY device. For those situations, a Device Tree
+binding allows to describe a "fixed link" using a special PHY node.
+
+This patch adds:
+
+ * A documentation for the fixed PHY Device Tree binding.
+
+ * An of_phy_is_fixed_link() function that an Ethernet driver can call
+   on its PHY phandle to find out whether it's a fixed link PHY or
+   not. It should typically be used to know if
+   of_phy_register_fixed_link() should be called.
+
+ * An of_phy_register_fixed_link() function that instantiates the
+   fixed PHY into the PHY subsystem, so that when the driver calls
+   of_phy_connect(), the PHY device associated to the OF node will be
+   found.
+
+These two additional functions also support the old fixed-link Device
+Tree binding used on PowerPC platforms, so that ultimately, the
+network device drivers for those platforms could be converted to use
+of_phy_is_fixed_link() and of_phy_register_fixed_link() instead of
+of_phy_connect_fixed_link(), while keeping compatibility with their
+respective Device Tree bindings.

++Fixed link Device Tree binding
++------------------------------
++
++Some Ethernet MACs have a "fixed link", and are not connected to a
++normal MDIO-managed PHY device. For those situations, a Device Tree
++binding allows to describe a "fixed link".
++
++Such a fixed link situation is described by creating a 'fixed-link'
++sub-node of the Ethernet MAC device node, with the following
++properties:
++
++* 'speed' (integer, mandatory), to indicate the link speed. Accepted
++  values are 10, 100 and 1000
++* 'full-duplex' (boolean, optional), to indicate that full duplex is
++  used. When absent, half duplex is assumed.
++* 'pause' (boolean, optional), to indicate that pause should be
++  enabled.
++* 'asym-pause' (boolean, optional), to indicate that asym_pause should
++  be enabled.
++
++Example:
++
++ethernet@0 {
++	...
++	fixed-link {
++	      speed = <1000>;
++	      full-duplex;
++	};
++	...
++};
