Subject: [PATCH net v3 2/4] net: phy: mscc: add support for VSC8501
Date:   Tue, 23 May 2023 17:31:06 +0200
Message-Id: <20230523153108.18548-3-david.epping@missinglinkelectronics.com>
In-Reply-To: <20230523153108.18548-1-david.epping@missinglinkelectronics.com>
References: <20230523153108.18548-1-david.epping@missinglinkelectronics.com>
Precedence: bulk

The VSC8501 PHY can use the same driver implementation as the VSC8502.
Adding the PHY ID and copying the handler functions of VSC8502 is
sufficient to operate it.
