The actual ECC strength used to select the ECC scheme is 'ecc_strength'.

Use it in the error message.

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;
|
||||
+ };
|
||||
+ ...
|
||||
+};

Subject: net: mvneta: add support for fixed links
|

|
||||

|
||||
