net: phy: add XFI, USXGMII types to is_10g_interface() helper

2020-03-09T23:11:25+00:00

The helper is used to reset PHYs on connect and it determines the clause
to use (C22/C45) based on interface type.  This fixes 'PHY reset timed out'
warnings in console for USXGMII/XFI PHYs.

phy: Include NC-SI in phy setup

2020-03-09T23:11:23+00:00

Add NC-SI to the usual phy handling. This makes two notable changes:
- Somewhat similar to a fixed phy, phy_connect() will create an NC-SI
phy if CONFIG_PHY_NCSI is defined.
- An early return is added to phy_read() and phy_write() to handle a
case like the NC-SI phy which does not define a bus.

phy: Add support for the NC-SI protocol

2020-03-09T23:11:23+00:00

This introduces support for the NC-SI protocol, modelled as a phy driver
for other ethernet drivers to consume.

NC-SI (Network Controller Sideband Interface) is a protocol to manage a
sideband connection to a proper network interface, for example a BMC
(Baseboard Management Controller) sharing the NIC of the host system.
Probing and configuration occurs by communicating with the "remote" NIC
via NC-SI control frames (Ethernet header 0x88f8).

This implementation is roughly based on the upstream Linux
implementation[0], with a reduced feature set and an emphasis on getting
a link up as fast as possible rather than probing the full possible
topology of the bus.
The current phy model relies on the network being "up", sending NC-SI
command frames via net_send_packet() and receiving them from the
net_loop() loop (added in a following patch).

The ncsi-pkt.h header[1] is copied from the Linux kernel for consistent
field definitions.

dm: core: Drop the inclusion of linux/compat.h in dm.h

2020-02-06T04:48:22+00:00

Most files don't need this header and it pulls in quite of lots of stuff,
malloc() in particular. Drop it.

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.
