Subject: [PATCH] net: phy: broadcom: Make LEDs 3+4 shadow LEDs 1+2
|
||
|
|
|
||
|
|
CM4 uses BCM54210PE, which supports 2 additional LEDs, choosing LED3
|
||
|
|
for the amber LED because it shows activity by default (LED4 is not
|
||
|
|
connected). However, this makes it uncontrollable by the eth_led<n>
|
||
|
|
dtparams which target LEDs 1+2.
|
||
|
|
|
||
|
|
Solve the problem by making LEDs 3+4 mirror LEDs 1+2 (which is much
|
||
|
|
simpler than adding baseboard-specific overrides, but comes with a
|
||
|
|
risk of making one of the LEDs redundant).
|
||
|
|
|
||
|
