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.

2018-07-26net: phy: dp83867: add workaround for incorrect RX_CTRL pin strapMurali Karicheri
The data manual for DP83867IR/CR, SNLS484E[1], revised march 2017, advises that strapping RX_DV/RX_CTRL pin in mode 1 and 2 is not supported (see note below Table 5 (4-Level Strap Pins)). It further advises that if a board has this pin strapped in mode 1 and mode 2, then bit[7] of Configuration Register 4 (address 0x0031) must be cleared to 0. This is to ensure proper operation of PHY. Since it is not possible to detect in software if RX_DV/RX_CTRL pin is incorrectly strapped, add a device-tree property to advertise this and allow corrective action in software.

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>

2018-03-13Move CONFIG_PHY_ADDR to KconfigStefan Mavrodiev
CONFIG_PHY_ADDR is used for old-style configuration. This makes impossible changing the PHY address, if multiple boards share a same config header file (for example include/configs/sunxi-common.h). Moving this to Kconfig helps overcoming this issue. It's defined as entry inside PHYLIB section. After the implemention, moveconfig was run. The issues are: - edb9315a - CONFIG_PHYLIB is not enabled. Entry is deleted. - ds414 - CONFIG_PHYLIB is in incompatible format: { 0x1, 0x0 }. This entry is also deleted. - devkit3250 - The PHY_ADDR is in hex format (0x1F). Manually CONFIG_PHY_ADDR=31 is added in the defconfig. After the changes the suspicious defconfigs passes building.

2017-12-18net: phy: meson-gxl: detect LPA corruptionJerome Brunet
This patch is ported from the Linux patch posted at [1] and applied to net tree as commit f1e2400a80ff. The purpose of this change is to fix the incorrect detection of the link partner (LP) advertised capabilities which sometimes happens with this PHY (roughly 1 time in a dozen) This issue may cause the link to be negotiated at 10Mbps/Full or 10Mbps/Half when 100MBps/Full is actually possible. In some case, the link is even completely broken and no communication is possible. To detect the corruption, we must look for a magic undocumented bit in the WOL bank (hint given by the SoC vendor kernel) but this is not enough to cover all cases. We also have to look at the LPA ack. If the LP supports Aneg but did not ack our base code when aneg is completed, we assume something went wrong. The detection of a corrupted LPA triggers a restart of the aneg process. This solves the problem but may take up to 6 retries to complete.

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.
