Subject: [PATCH v2 10/10] net: mvpp2: add explicit sgmii-2500 support
Date: Mon,  3 May 2021 08:08:53 +0200	[thread overview]
Message-ID: <20210503060853.3743626-11-sr@denx.de> (raw)
In-Reply-To: <20210503060853.3743626-1-sr@denx.de>

From: Marcin Wojtas <mw@semihalf.com>

Until now the mvpp2 driver used an extra 'phy-speed'
DT property in order to differentiate between the
SGMII and SGMII @2.5GHz. As there is a dedicated
PHY_INTERFACE_MODE_SGMII_2500 flag to mark the latter
start using it and drop the custom flag.
