net: Convert more users of mdiobus_* to mdiodev_*

2021-10-24T12:40:33+00:00

This converts users of mdiobus to mdiodev using the following semantic
patch:

@@
identifier mdiodev;
expression regnum;
@@

- mdiobus_read(mdiodev->bus, mdiodev->addr, regnum)
+ mdiodev_read(mdiodev, regnum)

- mdiobus_write(mdiodev->bus, mdiodev->addr, regnum, val)
+ mdiodev_write(mdiodev, regnum, val)

phy: bcm-ns-usb3: Remove redundant dev_err call in bcm_ns_usb3_mdio_probe()

2021-06-14T05:30:52+00:00

There is a error message within devm_ioremap_resource
already, so remove the dev_err call to avoid redundant
error message.

phy: phy-bcm-ns-usb3: drop support for deprecated DT binding

2020-11-19T06:26:35+00:00

Initially this PHY driver was implementing MDIO access on its own. It
was caused by lack of proper hardware design understanding.

It has been changed back in 2017. DT bindings were changed and driver
was updated to use MDIO layer.

It should be really safe now to drop the old deprecated code. All Linux
stored DT files don't use it for 3,5 year. There is close to 0 chance
there is any bootloader with its own DTB using old the binding.

phy: bcm-ns-usb3: add MDIO driver using proper bus layer

2017-06-16T07:52:26+00:00

As USB 3.0 PHY is attached to the MDIO bus this module should provide a
MDIO driver and use a proper bus layer. This is a proper (cleaner)
solution which doesn't require code to know this specific MDIO bus
details. It also allows reusing the driver with other MDIO buses.

For now keep platform device support in place. We may consider dropping
it once MDIO bindings gets used "everywhere".

phy: bcm-ns-usb3: enable MDIO in the platform specific code

2017-06-16T07:52:26+00:00

When we finally start using MDIO layer then bus initialization will be
handled in a separated driver. It means our code handling this has to be
used for the platform driver only.

phy: bcm-ns-usb3: use pointer for PHY writing function

2017-06-16T07:52:25+00:00

Our current writing function accesses PHY directly bypassing MDIO layer.

The aim is to extend this module to also behave as MDIO driver. This
will require using different writing function which can be handled
cleanly by having an extra pointer like this.

phy: bcm-ns-usb3: always wait for idle after writing to the PHY reg

2017-06-16T07:52:25+00:00

Move MDIO specific code to the writing helper function. This makes init
code a bit more generic and doesn't require it to track what happens
after every write.
