NOTE: Only for CI testing

Please do not submit a Pull Request via github. Our project makes use of
mailing lists for patch submission and review. For more details please
see https://u-boot.readthedocs.io/en/latest/develop/sending_patches.html

The only exception to this is in order to trigger a CI loop on Azure prior
to posting of patches.

net: ti: am65-cpsw / cpsw-mdio: Switch to DM MDIO
9f7edb5 
Hi,

This converts cpsw-mdio into a proper Driver Model
driver and introduces the new Config symbol CONFIG_MDIO_TI_CPSW.

It also cleans up the am65-cpsw driver so it porperly uses
the DM PHY interface.

It does not convert the legacy cpsw and keystone-net drivers.

Tested on AM64-EVM and AM335x BeagleBone.
AM64-EVM network doesn't work at 1G but only at 100M. This
limitation exists prior to this patch.

CI tests: u-boot#490

# Describe the purpose of this series. The information you put here
# will be used by the project maintainer to make a decision whether
# your patches should be reviewed, and in what priority order. Please be
# very detailed and link to any relevant discussions or sites that the
# maintainer can review to better understand your proposed changes. If you
# only have a single patch in your series, the contents of the cover
# letter will be appended to the "under-the-cut" portion of the patch.

# Lines starting with # will be removed from the cover letter. You can
# use them to add notes or reminders to yourself. If you want to use
# markdown headers in your cover letter, start the line with ">#".

# You can add trailers to the cover letter. Any email addresses found in
# these trailers will be added to the addresses specified/generated
# during the b4 send stage. You can also run "b4 prep --auto-to-cc" to
# auto-populate the To: and Cc: trailers based on the code being
# modified.

net: mdio: Handle bus level GPIO Reset
2a96e51 
Some platforms have bus level Reset controlled
by a GPIO line. If available then handle bus reset
via GPIO.

net: am65-cpsw: cpsw_mdio: Switch to proper DM_MDIO framework
553199c 
Add a new Kconfig symbol MDIO_TI_CPSW for the CPSW MDIO
driver and build it with proper DM support if enabled.

If MDIO_TI_CPSW is not enabled then we continue to
behave like before.

Clean up MDIO custom handling in am65-cpsw and use
dm_eth_phy_connect() to get the PHY.
