From b72413211b485da48099b20d733d342ff51e774b Mon Sep 17 00:00:00 2001 From: =?utf8?q?J=C3=A9r=C3=A9mie=20Dautheribes?= Date: Tue, 5 Mar 2024 15:13:09 +0100 Subject: [PATCH] dt-bindings: net: dp83822: change ti,rmii-mode description MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Drop reference to the 25MHz clock as it has nothing to do with connecting the PHY and the MAC. Add info about the reference clock direction between the PHY and the MAC as it depends on the selected rmii mode.
