From 9b2d84058445ae826548e2ba4f08b551b251d06f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Lothar=20Wa=C3=9Fmann?= Date: Tue, 17 Oct 2017 11:17:57 +0200 Subject: [PATCH] ARM: dts: imx6-tx6: specify ethernet phy reset post-delay MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
