Subject: [PATCH v4 04/12] phy: atheros: Explicitly disable RGMII delays
Date: Thu, 7 May 2020 00:11:51 +0200 [thread overview]
Message-ID: <20200506221159.1298-5-michael@walle.cc> (raw)
In-Reply-To: <20200506221159.1298-1-michael@walle.cc>
From: Vladimir Oltean <vladimir.oltean@nxp.com>
To eliminate any doubts about the out-of-reset value of the PHY, that
the driver previously relied on.
If bisecting shows that this commit breaks your board you probably have
a wrong PHY interface mode. You probably want the
PHY_INTERFACE_MODE_RGMII_RXID or PHY_INTERFACE_MODE_RGMII_ID mode.
