From efba9faf0c1bbf937989e03a75b9cf1d7ed59677 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Wed, 14 Dec 2022 15:28:16 +0000 Subject: [PATCH] dts: bcm2711: Add 'eee' dtparam The 'eee' dtparam allows EEE to be disabled on the onboard Ethernet controller. Adding 'dtparam=eee=off' to config.txt causes 'genet.eee=N' to be added to the kernel command line, which in turn tells the Genet driver to disable EEE.
