phy: make phy_connect_fixed work with a null mdio bus

2020-09-24T12:27:44Z

It is utterly pointless to require an MDIO bus pointer for a fixed PHY device. The fixed.c implementation does not require it, only phy_device_create. Fix that. Signed-off-by: Vladimir Oltean Signed-off-by: Hou Zhiqiang Reviewed-by: Priyanka Jain

net: phy: add phyid search in vendor specific space

2020-06-12T17:17:23Z

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. Signed-off-by: Florin Chiculita Reviewed-by: Madalin Bucur

net: phy: Fix overlong PHY timeout

2020-03-09T23:11:24Z

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

2020-03-09T23:11:23Z

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()

2019-12-09T15:47:42Z

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.

net: phy: Add gmiitorgmii converter support

2019-10-08T07:41:27Z

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. Signed-off-by: Siva Durga Prasad Paladugu Signed-off-by: Michal Simek
