Re: [PATCH net-next v2 4/6] net: ftgmac100: Require phy-mode for AST2700

The driver currently defaults to RGMII when the "phy-mode" property
is missing from the device tree. This default is no longer valid for
AST2700, which also supports RMII via FTGMAC100_QUIRK_RMII_ENABLE.

Make "phy-mode" a required property for AST2700 and fail probe with
an error message if it is not specified, instead of silently
defaulting to RGMII.

You need to update the DT binding, mark it as required for ast2700.
