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.
