2012-07-11phylib: phy_startup() should return an error code on failureTimur Tabi
phy_startup() calls the PHY driver's startup function, but it ignores the return code from that function, and so it never returns any failures. Signed-off-by: Timur Tabi <timur@freescale.com>
2012-02-27net: phy: make board_phy_config responsible for calling drv->configTroy Kisky
Boards may have things they want done before or after normal phy config. Letting the boards call drv->config allows them more flexibilty. Boards affected by this change are corenet_ds and mpc8544ds.

2011-12-05phy: Add support for SMSC LAN87xx PHYsNobuhiro Iwamatsu
This adds support for the SMSC LAN87xx PHYs. Following PHYs can be used by set CONFIG_PHY_SMSC to config. - SMSC LAN8700 - SMSC LAN8710/LAN8720 - SMSC LAN8710/LAN8720 A setup of PHY was copied from linux kenrel.

2011-09-28Revert "phylib: remove a couple of redundant code lines"Wolfgang Denk
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. Kudos to Andy Fleming <afleming@gmail.com> for binging this to attention and for the explanation. Signed-off-by: Wolfgang Denk <wd@denx.de>

This change slightly improves readability of the phydev speed/duplex assignment logic. Signed-off-by: Vladimir Zapolskiy <vz@mleia.com> Acked-by: Detlev Zundel <dzu@denx.de>
2011-09-10phylib: reset mii bus only if reset handler is registeredVladimir Zapolskiy
This change allows to cope with a mii bus device registered using miiphy_register(), which doesn't assign a default reset handler. Signed-off-by: Vladimir Zapolskiy <vz@mleia.com> Acked-by: Detlev Zundel <dzu@denx.de>
2011-08-31phy.c: make less verbose - turn printf() into debug()Wolfgang Denk
The PHY driver was too verbose and corrupted the boot message display like this: ... Net: TSEC0 connected to Marvell 88E1111S TSEC1 connected to Marvell 88E1111S TSEC0, TSEC1 ... Turn printf() into debug() so we het the expected output again: ... Net: TSEC0, TSEC1 ... Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: Kumar Gala <galak@kernel.crashing.org>
2011-04-20phylib: Add a bunch of PHY drivers from tsecAndy Fleming
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.

2011-04-20Create PHY Lib for U-BootAndy Fleming
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.
