Required properties:
-- compatible : Should be "ti,cpsw"
+- compatible : Should be one of the below:-
+ "ti,cpsw" for backward compatible
+ "ti,am335x-cpsw" for AM335x controllers
+ "ti,am4372-cpsw" for AM437x controllers
+ "ti,dra7-cpsw" for DRA7x controllers
- reg : physical base address and size of the cpsw
registers map
- interrupts : property with a value describing the interrupt

Optional properties:
- dual_emac : Specifies Switch to act as Dual EMAC
- syscon : Phandle to the system control device node, which is
the control module device of the am33x

+- mode-gpios : Should be added if one/multiple gpio lines are
+ required to be driven so that cpsw data lines
+ can be connected to the phy via selective mux.
+ For example in dra72x-evm, pcf gpio has to be
+ driven low so that cpsw slave 0 and phy data
+ lines are connected via mux.
