[PATCH RESEND net-next 0/4] net: mdio: Remove support for building C45 muxed addresses

[PATCH RESEND net-next 0/4] net: mdio: Remove support for building C45 muxed addresses

[Michael Walle]

[Russell told me that his mailserver rejected my mail because of
an ill-formated "To:" header. Resending now with plain git-send-email
instead of b4 send.]

I've picked this older series from Andrew up and rebased it onto
the latest net-next.

With all drivers which support c45 now being converted to a seperate c22
and c45 access op, we can now remove the old MII_ADDR_C45 flag.

  net: Remove C45 check in C22 only MDIO bus drivers
  net: mdio: Remove support for building C45 muxed addresses

[PATCH RESEND net-next 1/4] net: phy: Remove fallback to old C45 method

[Michael Walle]

From: Andrew Lunn <andrew@lunn.ch>

Now that all MDIO bus drivers which support C45 implement the c45
specific ops, remove the fallback to the old method.

[PATCH RESEND net-next 2/4] net: ngbe: Drop mdiobus_c45_regad()

[Michael Walle]

With the new C45 MDIO access API, there is no encoding of the register
number anymore and thus the masking isn't necessary anymore. Remove it.

[PATCH RESEND net-next 3/4] net: Remove C45 check in C22 only MDIO bus drivers

[Michael Walle]

From: Andrew Lunn <andrew@lunn.ch>

The MDIO core should not pass a C45 request via the C22 API call any
more. So remove the tests from the drivers.

[PATCH RESEND net-next 3/4] net: Remove C45 check in C22 only MDIO bus drivers

[Michael Walle]

From: Andrew Lunn <andrew@lunn.ch>

The MDIO core should not pass a C45 request via the C22 API call any
more. So remove the tests from the drivers.

[PATCH RESEND net-next 4/4] net: mdio: Remove support for building C45 muxed addresses

[Michael Walle]

From: Andrew Lunn <andrew@lunn.ch>

The old way of performing a C45 bus transfer created a special
register value and passed it to the MDIO bus driver, in the hope it
would see the MII_ADDR_C45 bit set, and perform a C45 transfer. Now
that there is a clear separation of C22 and C45, this scheme is no
longer used. Remove all the #defines and helpers, to prevent any code
being added which tries to use it.
