Come on... Can you guess what I'm going to say here.

Ooops, I missed that one.


+- reg : Offset and length of the register regions for the device
+- reg-names : Register region names referenced in 'reg' above.
+ Required register resource entries are:
+ "base" : EMAC controller base register block.
+ "csr" : EMAC wrapper register block.
+ Optional register resource entries are:
+ "ptp" : EMAC PTP (1588) register block.
+ Required if 'qcom,emac-tstamp-en' is present.
+ "sgmii" : EMAC SGMII PHY register block.
+- interrupts : Interrupt numbers used by this controller
+- interrupt-names : Interrupt resource names referenced in 'interrupts' above.
+ Required interrupt resource entries are:
+ "emac_core0" : EMAC core0 interrupt.
+ "sgmii_irq" : EMAC SGMII interrupt.
+- phy-addr : Specifies phy address on MDIO bus.
+ Required if the optional property "qcom,no-external-phy"
+ is not specified.

As I mentioned in the last version, you should still describe this with
a standard MDIO bus binding even if you can't use the generic code.

You mean like this?

phy0: ethernet-phy@0 {
compatible = "qcom,fsm9900-emac-phy";
reg = <4>;
};

+Optional properties:
+- qcom,emac-tstamp-en : Enables the PTP (1588) timestamping feature.
+ Include this only if PTP (1588) timestamping
+ feature is needed. If included, "ptp" register
+ base should be specified.
+- mac-address : The 6-byte MAC address. If present, it is the
+ default MAC address.
+- qcom,no-external-phy : Indicates there is no external PHY connected to
+ EMAC. Include this only if the EMAC is directly
+ connected to the peer end without EPHY.
+Example:
+ emac0: qcom,emac@feb20000 {

ethernet@

+ compatible = "qcom,fsm9900-emac";

Ah, I see you fixed it here...

and in the code, I just missed it in the top of the file. I'll fix it everywhere in v5.
