net: phy: add phyid search in vendor specific space

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

There are devices accesible through mdio clause-45, such as
retimers, that do not have PMA or PCS blocks.
This patch adds MDIO_MMD_VEND1 on the list of device addresses
where phyid is searched. Previous order of devices was kept.

net: phy: Fix overlong PHY timeout

2020-03-09T23:11:24+00:00

Commit 27c3f70f3b50 ("net: phy: Increase link up delay in
genphy_update_link()") increased the per-iteration waiting time from
1ms to 50ms, without adjusting the timeout counter. This lead to the
timeout increasing from the typical 4 seconds to over three minutes.

Adjust the timeout counter evaluation by that factor of 50 to bring the
timeout back to the intended value.

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.

net: phy: Increase link up delay in genphy_update_link()

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

I've noticed that in most cases when genphy_update_link() is called, the
ethernet driver (mt7628-eth in this case) fails with the first ethernet
packets. Resulting in a timeout of the first tftp command. Increasing
the delay in the link check look from 1 to 50 ms and moving it below the
BMSR register read fixes this issue, resulting in a stable ethernet
traffic, even after initial link autonogotiation.

Fix 'mask' calculation in phy_connect() for phy addr '0'.
'mask' is getting set to '0xffffffff' for phy addr '0'
in phy_connect() whereas expected value is '0'.

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.
