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.
|
||
|
|
|
||
|
|
