Subject: [PATCH 0186/1002] net:phy:2711 Allow ethernet LED mode to be set via
|
|
device tree
|
|
|
|
Add device tree entries and code to allow the specification of
|
|
the lighting modes for the LED's on the ethernet connector.
|
|
|
|
Signed-off-by: James Hughes <james.hughes@raspberrypi.org>
|
|
|
|
net:phy:2711 Change the default ethernet LED actions
|
|
|
|
This should return default behaviour back to that of previous
|
|
releases.
