+Qualcomm EMAC Gigabit Ethernet Controller
+
+Required properties:
+- cell-index : EMAC controller instance number.
+- compatible : Should be "qcom,emac".
This should be more specific with the SOC name.
+- 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.
+- qcom,emac-gpio-mdc : GPIO pin number of the MDC line of MDIO bus.
+- qcom,emac-gpio-mdio : GPIO pin number of the MDIO line of MDIO bus.
Use the standard binding for GPIO controlled MDIO bus.
+- phy-addr : Specifies phy address on MDIO bus.
+ Required if the optional property "qcom,no-external-phy"
+ is not specified.
Don't you think you will need to know the specific phy device or other
properties of the phy?
+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.
Isn't this a user enabled feature if the h/w supports it?
