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