Subject: [PATCH] ARM: dts: imx6sx-udoo-neo: Pass the 'phy-reset-duration' property
Date: Mon, 5 Dec 2016 17:28:39 -0200 [thread overview]
Message-ID: <1480966119-17350-1-git-send-email-festevam@gmail.com> (raw)
From: Fabio Estevam <fabio.estevam@nxp.com>
imx6sx-udoo-neo has a KSZ8091 Ethernet PHY, which requires the reset
signal to be low for at least 10ms.
Pass the 'phy-reset-duration' property to reflect such requirement.
