Subject: [PATCHv3 06/12] ARM: dts: imx6-tx6: specify ethernet phy reset post-delay
Date: Tue, 17 Oct 2017 11:17:57 +0200 [thread overview]
Message-ID: <1508231883-12067-7-git-send-email-LW@KARO-electronics.de> (raw)
In-Reply-To: <1508231883-12067-1-git-send-email-LW@KARO-electronics.de>
Under certain circumstances the ethernet PHY cannot be detected on
Ka-Ro electronics TX6 modules. Using a phy-reset-post-delay of at least
2ms alleviates this problem. Define it to 10ms to be on the safe side.
