54337abb14 phy: adin: add support for clock output
The ADIN1300 supports generating certain clocks on its GP_CLK pin, as
well as providing the reference clock on CLK25_REF.

Add support for selecting the clock via device-tree properties.

This patch is based on the Linux implementation for this feature,
which has been added to netdev/net-next.git [1].

4cc25cd5ce phy: adin: fix broken support for adi, phy-mode-override
Currently, the adin driver fails to compile.

The original patch introducing the adin driver used the function
phy_get_interface_by_name to support the adi,phy-mode-override
property. Unfortunately, a few days before the adin patch
was accepted, another patch removed support for phy_get_interface_by_name:

This patch refactors adin_get_phy_mode_override, implementing the logic in
the new function, ofnode_read_phy_mode, from the patch above.

d79f1a8569 phy: adin: add driver for Analog Devices ADIN1300 PHY
The current implementation configures RGMII using device tree phy-mode
property and then calls genphy_config

adin_config_rgmii_mode is derived from:
