since the 911x sits on a chipselect bus, you should instead add that
bus to the dtsi and define this on that bus.
Something like this in the dtsi:
sromc-bus {
#address-cells = <2>;
#size-cells = <1>;
ranges = < 0 0 0x04000000 0x20000
1 0 0x05000000 0x20000
2 0 0x06000000 0x20000
3 0 0x07000000 0x20000>;
};
and in the dts:
sromc-bus {
lan9215@1,0 {
compatible = "smsc,lan9215", "smsc,lan9115";
reg = <1 0 0x20000>;
interrupts = <5 0>;
interrupt-parent = <&wakeup_eint>;
phy-mode = "mii";
smsc,irq-push-pull;
smsc,force-internal-phy;
local-mac-address = [00 80 00 23 45 67];
};
};
(You might be able to do just fine with one address cell, I'm not 100%
sure why Grant's example uses two, but I used the same above for
consistency).
Also, I don't think it's a good idea to hardcode the mac address in
the dts like this; have u-boot fill it in from the environment
variable there instead, if needed.
