From 9de4695f757537f87186f268264a333d681cb811 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Sun, 23 Jun 2019 00:42:14 -0500 Subject: [PATCH] ARM: am3517-evm: Remove manual ethernet reset code The reset line going to the ethernet controller is controlled by a global reset controlling multiple peripherals. There is no need to manually invoke the reset.
