Subject: [PATCH net-next 1/3] dt-bindings: net: dp83822: support configuring RMII master/slave mode
Date: Thu, 22 Feb 2024 11:31:15 +0100 [thread overview]
Message-ID: <20240222103117.526955-2-jeremie.dautheribes@bootlin.com> (raw)
In-Reply-To: <20240222103117.526955-1-jeremie.dautheribes@bootlin.com>
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.
