Subject: [PATCH 258/454] BCM27XX_DT: Set LED modes from Device Tree
|
||
|
|
|
||
|
|
The new default values for LAN7515 (LAN7800) are:
|
||
|
|
|
||
|
|
LED0 = 1 (link1000/activity)
|
||
|
|
LED1 = 6 (link10/link100/activity)
|
||
|
|
|
||
|
|
Also add two dtparams - eth_led0 and eth_led1 - to provide user control
|
||
|
|
over the LEDs.
|
||
|
|
|
||
|
