From: Richard Genoud <richard.genoud@bootlin.com> The H616 has a secondary EMAC controller that supports only RMII at 10/100 Mbps. It connects through PA0-PA9 to an EPHY in a companion AC200 or AC300 package. Add the EMAC1 controller and RMII pin group. Leave the controller disabled for boards to enable when the companion Ethernet hardware is present.
