Merge branch 'dsa-Plug-in-PHYLINK-support'
Florian Fainelli says:
====================
net: dsa: Plug in PHYLINK support
This patch series adds PHYLINK support to DSA which is necessary to support more
complex PHY and pluggable modules setups.
Patch series can be found here:
https://github.com/ffainelli/linux/commits/dsa-phylink-v2
This was tested on:
- dsa-loop
- bcm_sf2
- mv88e6xxx
- b53
With a variety of test cases:
- internal & external MDIO PHYs
- MoCA with link notification through interrupt/MMIO register
- built-in PHYs
- ifconfig up/down for several cycles works
- bind/unbind of the drivers
Changes in v2:
- fixed link configuration for mv88e6xxx (Andrew) after introducing polling
This is technically v2 of what was posted back in March 2018, changes from last
time:
- fixed probe/remove of drivers
- fixed missing gpiod_put() for link GPIOs
- fixed polling of link GPIOs (Russell I would need your SoB on the patch you
provided offline initially, added some modifications to it)
- tested across a wider set of platforms
And everything should still work as expected. Please be aware of the following:
- switch drivers (like bcm_sf2) which may have user-facing network ports using
fixed links would need to implement phylink_mac_ops to remain functional.
PHYLINK does not create a phy_device for fixed links, therefore our
call to adjust_link() from phylink_mac_link_{up,down} would not be calling
into the driver. This *should not* affect CPU/DSA ports which are configured
through adjust_link() but have no network devices
- support for SFP/SFF is now possible, but switch drivers will still need some
modifications to properly support those, including, but not limited to using
the correct binding information. This will be submitted on top of this series
Please do test on your respective platforms/switches and let me know if you
find any issues, hopefully everything still works like before.
