From: Dinh Nguyen dinguyen@kernel.org Date: Wed, 13 Mar 2019 17:28:37 -0500 Subject: [PATCH] arm64: dts: stratix10: add the sysmgr-syscon property from the gmac's

The gmac ethernet driver uses the "altr,sysmgr-syscon" property to configure phy settings for the gmac controller.

Add the "altr,sysmgr-syscon" property to all gmac nodes.

This patch fixes:
