2019-10-08net: phy: Add gmiitorgmii converter supportSiva Durga Prasad Paladugu
This patch adds support for gmiitorgmii converter. This converter sits between the MAC and the external phy MAC <==> GMII2RGMII <==> RGMII_PHY. The ethernet driver probes this bridge and this bridge driver probes real phy driver and invokes the real phy functionalities as requested. This bridge just needs to be configured based on real phy negotiated speed and duplex.

2019-05-07net: phy: Add generic helpers to access MMD PHY registersCarlo Caione
Two new helper functions (phy_read_mmd() and phy_write_mmd()) are added to allow access to the MMD PHY registers. The MMD PHY registers can be accessed by several means: 1. Using two new MMD access function hooks in the PHY driver. These functions can be implemented when the PHY driver does not support the standard IEEE Compatible clause 45 access mechanism described in clause 22 or if the PHY uses its own non-standard access mechanism. 2. Direct access for C45 PHYs and C22 PHYs when accessing the reachable DEVADs. 3. The standard clause 45 access extensions to the MMD registers through the indirection registers (clause 22) in all the other cases.

2018-07-26net: phy: add ofnode node to struct phy_deviceGrygorii Strashko
Now the UCLASS_ETH device "node" field is owerwritten by some network drivers in case of Ethernet PHYs which are linked to UCLASS_ETH device using "phy-handle" DT property and when Ethernet PHY driver needs to read some additional information from DT. In such cases following happens (in general): - network drivers priv->phydev = phy_connect(priv->bus, priv->phyaddr, dev, priv->interface); <-- phydev is connected to dev which is UCLASS_ETH device if (priv->phy_of_handle > 0) dev_set_of_offset(priv->phydev->dev, priv->phy_of_handle); <-- phydev->dev->node is overwritten by phy-handle DT node - PHY driver in .config() callback int node = dev_of_offset(dev); <-- PHY driver uses overwritten dev->node const void *fdt = gd->fdt_blob; if (fdtdec_get_bool(fdt, node, "property")) ... As result, UCLASS_ETH device can't be used any more for DT accessing. This patch adds additional ofnode node field to struct phy_device which can be set explicitly by network drivers and used by PHY drivers, so overwriting can be avoided. Also add helper function phy_get_ofnode() which will check and return phy_device->node or dev_ofnode(phydev->dev) for backward compatibility with existing drivers.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

Add a minimalistic Broadcom BCM53xx (roboswitch) switch driver similar to the Marvell MV88E617x.

2017-08-07net: phy: micrel: Separate KSZ9000 drivers from KSZ8000 driversAlexandru Gagniuc
The KS8721BL and KSZ9021 PHYs are software-incompatible, yet they share the same ID. Drivers for bothe PHYs cannot safely coexist, so the solution was to use #ifdefs to select between the two drivers. As a result KSZ9031, which has a unique ID, is now caught in the crossfire. Unless CONFIG_PHY_MICREL_KSZ9031 is defined, the KSZ9031 will not function properly, as some essential configuration code is ifdef'd-out. To prevent such situations, move the KSZ9000 drivers to a separate file, and place them under a separate Kconfig option. While it is possible to enable both KSZ8000 and KSZ9000 drivers at the same time, the assumption is that it is highly unlikely for a system to contain both a KSZ8000 and a KSZ9000 PHY, and that only one of the drivers will be enabled at any given time.

2017-03-26drivers/net/phy: add fixed-phy / fixed-link supportHannes Schmelzer
This patch adds support for having a "fixed-link" to some other MAC (like some embedded switch-device). For this purpose we introduce a new phy-driver, called "Fixed PHY". Fixed PHY works only with CONFIG_DM_ETH enabled, since the fixed-link is described with a subnode below ethernet interface. Most ethernet drivers (unfortunately not all are following same scheme for searching/attaching phys) are calling "phy_connect(...)" for getting a phy-device. At this point we link in, we search here for a subnode called "fixed- link", once found we start phy_device_create(...) with the special phy- id PHY_FIXED_ID (0xa5a55a5a). During init the "Fixed PHY" driver has registered with this id and now gets probed, during probe we get all the details about fixed-link out of dts, later on the phy reports this values.

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.
