[PATCH net-next v6 2/3] dt-bindings: net: allwinner: add H616 EMAC1

From: James Hilliard

Date: Sun Sep 27 2026 - 14:54:06 EST


The H616 secondary EMAC uses a separate system-control clock register
and supports only RMII at 10/100 Mbps. Add its distinct compatible
without an older fallback, since using the primary EMAC clock register
would not work.

Constrain the PHY interface mode to RMII, matching the hardware.
