Subject: [PATCH net-next v3 3/6] net: stmmac: add support to provide pcs from platform data
Date:   Thu,  9 Feb 2023 16:16:29 +0100
Message-Id: <20230209151632.275883-4-clement.leger@bootlin.com>
In-Reply-To: <20230209151632.275883-1-clement.leger@bootlin.com>

Precedence: bulk

Add a pcs field in platform_data to allow providing platform data. This is
going to be used by the "renesas,rzn1-gmac" compatible driver which can make
use of a PCS.
