Subject: [PATCH] net: phy: realtek: add led-link-select for RTL8221
|
||||||
|
|
||||||
|
RTL8221B PHYs will select the different speeds for 3 LEDs to 10M/100M/1G
|
||||||
|
respectively by default. Some devices like TP-Link TL-XDR6088/TL-XDR6086
|
||||||
|
have only one LED connects to the PHY chip LED0. If we didn't change the
|
||||||
|
default settings, the LED will only blink at 10M speed.
|
||||||
|
|
||||||
|
This patch allows configuring LED link select bitmask from DT. And it
|
||||||
|
has been tested with TP-Link XDR6088 with different DT configurations.
