Micrel KSZ8041RNLI supports LED mode, just like KSZ8041.
This fixes (a.o.) the following "make dtbs_check" warning:
arch/arm/boot/dts/renesas/r8a7791-koelsch.dtb: ethernet-phy@1 (ethernet-phy-id0022.1537): False schema does not allow 1

|
If present the PHY is configured to operate in fiber mode.
|
|
|
|
The KSZ8041FTL variant supports fiber mode, enabled by the FXEN
|
|
boot strapping pin. It can't be determined from the PHY registers
|
|
whether the PHY is in fiber mode, so this boolean device tree
|
|
property can be used to describe it.
|
|
|
|
In fiber mode, auto-negotiation is disabled and the PHY can only
|
|
work in 100base-fx (full and half duplex) modes.
