From mboxrd@z Thu Jan 1 00:00:00 1970 From: nhed+uboot at starry.com Date: Tue, 6 Aug 2019 11:51:43 -0400 Subject: [U-Boot] [PATCH v3 6/7] net: mvpp2: use new MVMDIO driver In-Reply-To: <20190806155144.19301-1-nhed+uboot@starry.com> References: <20190806155144.19301-1-nhed+uboot@starry.com> Message-ID: <20190806155144.19301-7-nhed+uboot@starry.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de From: Nevo Hed An earlier commit in this changeset is taken from Marvells repos but was based on an MVMDIO implementation that never made it into U-Boot. With this patch the mvpp2 driver switches to use the new MVMDIO driver that is based on a more universal mdio-uclass implementation.
