* net: phy: delay only if reset handler is registeredJörg Krause2015-08-11-3/+5
| | | | | | | | With commit e3a77218a256edbe201112a39beeed8adcabae3f the MII bus is only reset if a reset handler is registered. If there is no reset handler there is no need to wait for a device to come out of the reset. Signed-off-by: Jörg Krause <joerg.krause@embedded.rocks>

* dm: net: Adjust PHY interface to work with CONFIG_DM_ETHSimon Glass2015-04-18-0/+22
| | | | | | | | | | | | When driver model is used for Ethernet a few functions are passed a udevice instead of an eth_device. Also add a function to find a PHY type given its name. This will be used to decode the device tree node. Finally, put a phy_interface field in struct eth_pdata since this is an important part of the platform data for Ethernet.

* phy: fix 10/100Mbps operation on 1Gbps-capable linksSascha Silbe2013-07-19-1/+9
| | | | | | | | | | | | | | | | | de1d786 [add support for Xilinx 1000BASE-X phy (GTX)] introduced a check for the extended status register in order to support 1Gbps-capable PHYs that don't have the 1000BASE-T registers. Since Extended Status only indicates what the PHY (i.e. the local side) is capable of, this broke communication with non-1Gbps peers. Only check the extended status if the 1000BASE-T registers are actually missing so we don't end up setting speed to 1Gbps even though the previous test (for the combination of local and peer support for 1Gbps) already indicated we can't do 1Gbps with the current peer.

* Revert "phylib: remove a couple of redundant code lines"Wolfgang Denk2011-09-28-2/+5
| | | | | | | | | | | | | | | | | | | | | | This reverts commit 041c542219af7f31c372d89b4c7c6f4c8064a8ce. The lines removed by this commit weren't redundant. The logic is (and probably should be better commented): Find the intersection of the advertised capabilities of both sides of the link (lpa). From that intersection, find the highest capability we can run at (that will be the negotiated link). Now imagine that the intersection (lpa) is (LPA_100HALF | LPA_10FULL). The code will now set phydev->speed to 100, and phydev->duplex to 1, but this link does not support 100FULL.

| | | | | | | | | | | | | | | | The tsec driver had a bunch of PHY drivers already written. This converts them all into PHY Lib drivers, and serves as the first set of PHY drivers for PHY Lib. While doing that, cleaned up a number of magic numbers (though not all of them, as PHY vendors like to keep their numbers as magical as possible). Also, noticed that almost all of the vitesse/cicada PHYs had the same config/parse/startup functions, so those have been collapsed into one.

* Create PHY Lib for U-BootAndy Fleming2011-04-20-0/+724
Extends the mii_dev structure to participate in a full-blown MDIO and PHY driver scheme. The mii_dev structure and miiphy calls are modified in such a way to allow the original mii command and miiphy infrastructure to work as before, but also to support a new set of APIs which allow (among other things) sharing of PHY driver code and 10G support The mii command will continue to support normal PHY management functions (Clause 22 of 802.3), but will not be changed to support 10G (Clause 45). The basic design is similar to PHY Lib from Linux, but simplified for U-Boot's network and driver infrastructure. We now have MDIO drivers and PHY drivers An MDIO driver provides: read write reset A PHY driver provides: (optionally): probe config - initial setup, starting of auto-negotiation startup - waiting for AN, and reading link state shutdown - any cleanup needed The ethernet drivers interact with the PHY Lib using these functions: phy_connect() phy_config() phy_startup() phy_shutdown() Each PHY driver can be configured separately, or all at once using config_phylib_all_drivers.h (added in the patch which adds the drivers) We also provide generic drivers for Clause 22 (10/100/1000), and Clause 45 (10G) PHYs. We also implement phy_reset(), and call it in phy_connect(). Because phy_reset() is essentially the same as miiphy_reset, but: a) must support 10G PHYs, and b) should use the phylib primitives, we implement miiphy_reset, using phy_reset(), but only when CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this way, we save on compile size, even if we don't manage to save code size.
