include: phy: add data field for private driver data

2019-12-09T15:47:42+00:00

This is useful to carry custom information between the driver structure
associated with a specific HW and the driver code.

net: phy: Add gmiitorgmii converter support

2019-10-08T07:41:27+00:00

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.

net: add comments to phy APIs

2019-07-18T21:37:13+00:00

Added a comment on the limitations of phy_find_by_mask API when scanning
MDIO buses with multiple PHYs present.  Added short descriptions to the
other APIs in phy.h for consistency.

net: phy: Add generic helpers to access MMD PHY registers

2019-05-07T19:51:55+00:00

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.

net: phy: Add clause 45 identifier to phy_device

2019-01-24T17:35:26+00:00

The phy devices can be accessed via clause 22 or via clause 45.
This information can be deduced when we read phy id. if the phy id
is read without giving any MDIO Manageable Device Address (MMD), then
it conforms to clause 22. otherwise it conforms to clause 45.

net: phy: add ofnode node to struct phy_device

2018-07-26T19:08:22+00:00

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.

phy: Break include cycle

2018-07-26T19:08:22+00:00

Because some phy wants to export some functions [1], export.h was
including the whole phy subsystem which pulls in lots of stuff that
causes some ordering and redefinition issues. Split out the only part
that is actually needed in export.h and include it there and in phy.h.

net/phy/cortina: Add support for CS4223 PHY

2018-06-13T18:54:15+00:00

Add support for Cortina CS4223 10G PHY
  - As per the CS4223 specs, an EEPROM module is
    connected to the PHY. At startup the PHY reads
    the firmware line and tries to load the firmware
    into the internal memory.
  - This driver reads the EEPROM status
    and checks if firmware has been loaded
