Subject: [PATCH net-next 0/7] net: lan969x: add RGMII support

== Description:

This series is the fourth of a multi-part series, that prepares and adds
support for the new lan969x switch driver.

The upstreaming efforts is split into multiple series (might change a
bit as we go along):

        1) Prepare the Sparx5 driver for lan969x (merged)

        2) Add support for lan969x (same basic features as Sparx5
           provides excl. FDMA and VCAP, merged).

        3) Add lan969x VCAP functionality (merged).

    --> 4) Add RGMII support.

        5) Add FDMA support.

== RGMII support:

The lan969x switch device includes two RGMII interfaces (port 28 and 29)
supporting data speeds of 1 Gbps, 100 Mbps and 10 Mbps.

Details are in the commit description of the patches.

== Patch breakdown:

Patch #1 does some preparation work.

Patch #2 adds new function: is_port_rgmii() to the match data ops.

Patch #3 uses the is_port_rgmii() in a number of places.

Patch #4 uses the phy_interface_mode_is_rgmii() in a number of places.

Patch #5 adds checks for RGMII PHY modes in sparx5_verify_speeds().

Patch #6 adds registers required to configure RGMII.

Patch #7 adds RGMII configuration function and uses it.
