net: Drop dm.h header file from phy.h

2020-08-04T02:19:54+00:00

This header file should not be included in other header files. Remove it
and use other headers and C inclusions instead.

net: phy: Add helper routines to set and clear bits

2020-06-12T17:17:23+00:00

Add phy_set/clear_bit helper routines so that ported drivers from the
kernel can use these functions.

net: phy: Fix kernel doc issues in phy.h

2020-06-12T17:17:23+00:00

Fix kernel doc warnings in phy.h.  Mostly the warnings were due to the
return missing the semi-colon.

net: phy: Add missing kernel doc to phy functions

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

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.
