Subject: [PATCH 2/7] ARM: dts: imx6ul-txul: specify ethernet phy reset post-delay
Date: Fri, 13 Oct 2017 12:42:58 +0200 [thread overview]
Message-ID: <1507891383-15452-3-git-send-email-LW@KARO-electronics.de> (raw)
In-Reply-To: <1507891383-15452-1-git-send-email-LW@KARO-electronics.de>
Under certain circumstances the ethernet PHY cannot be detected on
Ka-Ro electronics TXUL modules. Using a phy-reset-post-delay of > 5ms
alleviates this problem. Specify a value of 10ms to be on the safe side.
