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;
+ };
+ ...
+};

The WRT1900AC among other Linksys routers uses a dual-firmware layout.
The bootloader passes the active rootfs in bootargs and also sets the
rootfstype to jffs2 - which is clearly something we don't want.
Rename both root= and rootfstype= variables to avoid issues and also
use the former to dynamically rename the active partition to "ubi".
