+TI SoC Ethernet Switch Controller Device Tree Bindings
+------------------------------------------------------
+
+Required properties:
+- 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
+ number
+- cpdma_channels : Specifies number of channels in CPDMA
+- ale_entries : Specifies No of entries ALE can hold
+- bd_ram_size : Specifies internal descriptor RAM size
+- mac_control : Specifies Default MAC control register content
+ for the specific platform
+- slaves : Specifies number for slaves
+- active_slave : Specifies the slave to use for time stamping,
+ ethtool and SIOCGMIIPHY
+- cpsw-phy-sel : Specifies the phandle to the CPSW phy mode selection
+ device. See also cpsw-phy-sel.txt for its binding.
+ Note that in legacy cases cpsw-phy-sel may be
+ a child device instead of a phandle
+ (DEPRECATED, use phys property instead).
+
+Optional properties:
+- ti,hwmods : Must be "cpgmac0"
+- 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.
+- cpts_clock_mult : Numerator to convert input clock ticks into nanoseconds
+- cpts_clock_shift : Denominator to convert input clock ticks into nanoseconds
+ Mult and shift will be calculated basing on CPTS
+ rftclk frequency if both cpts_clock_shift and
+ cpts_clock_mult properties are not provided.
+
+Slave Properties:
+Required properties:
+- phy-mode : See ethernet.txt file in the same directory
+- phys : phandle on phy-gmii-sel PHY (see phy/ti-phy-gmii-sel.txt)
+
+Optional properties:
+- dual_emac_res_vlan : Specifies VID to be used to segregate the ports
+- phy_id : Specifies slave phy id (deprecated, use phy-handle)
+- phy-handle : See ethernet.txt file in the same directory
+
+The MAC address will be determined using the optional properties
+defined in ethernet.txt.
+
+Slave sub-nodes:
+- fixed-link : See fixed-link.txt file in the same directory
+
+Note: Exactly one of phy_id, phy-handle, or fixed-link must be specified.
+
+Note: "ti,hwmods" field is used to fetch the base address and irq
+resources from TI, omap hwmod data base during device registration.
+Future plan is to migrate hwmod data base contents into device tree
+blob so that, all the required data will be used from device tree dts
+file.
