From 95f4fa1f459a69827d752bd55205af7c55b76e4e Mon Sep 17 00:00:00 2001 From: =?utf8?q?J=C3=A9r=C3=A9mie=20Dautheribes?= Date: Thu, 22 Feb 2024 11:31:15 +0100 Subject: [PATCH] dt-bindings: net: dp83822: support configuring RMII master/slave mode MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Add property ti,rmii-mode to support selecting the RMII operation mode between: - master mode (PHY operates from a 25MHz clock reference) - slave mode (PHY operates from a 50MHz clock reference) If not set, the operation mode is configured by hardware straps.
