+TI SoC Ethernet Switch Controller Device Tree Bindings
+------------------------------------------------------
+
+Required properties:
+- compatible : Should be "ti,cpsw"
+- reg : physical base address and size of the cpsw
+ registers map
+- interrupts : property with a value describing the interrupt
+ number
+- interrupt-parent : The parent interrupt controller
+- cpdma_channels : Specifies number of channels in CPDMA
+- host_port_no : Specifies host port shift
+- cpdma_reg_ofs : Specifies CPDMA submodule register offset
+- ale_reg_ofs : Specifies ALE submodule register offset
+- ale_entries : Specifies No of entries ALE can hold
+- host_port_reg_ofs : Specifies host port register offset
+- hw_stats_reg_ofs : Specifies hardware statistics register offset
+- bd_ram_ofs : Specifies internal desciptor RAM offset
+- bd_ram_size : Specifies internal descriptor RAM size
+- rx_descs : Specifies number of Rx descriptors
+- mac_control : Specifies Default MAC control register content
+ for the specific platform
+- slaves : Specifies number for slaves
+- slave_reg_ofs : Specifies slave register offset
+- sliver_reg_ofs : Specifies slave sliver register offset
+- phy_id : Specifies slave phy id
+- mac-address : Specifies slave MAC address
+
+Optional properties:
+- ti,hwmods : Must be "cpgmac0"
+- no_bd_ram : Must be 0 or 1
+
+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.
+
+Examples:
+
+ mac: ethernet@4A100000 {
+ compatible = "ti,cpsw";
+ reg = <0x4A100000 0x1000>;
+ interrupts = <55 0x4>;
+ interrupt-parent = <&intc>;
+ cpdma_channels = 8;
+ host_port_no = 0;
+ cpdma_reg_ofs = 0x800;
+ ale_reg_ofs = 0xd00;
+ ale_entries = 1024;
+ host_port_reg_ofs = 0x108;
+ hw_stats_reg_ofs = 0x900;
+ bd_ram_ofs = 0x2000;
+ bd_ram_size = 0x2000;
+ no_bd_ram = 0;
+ rx_descs = 64;
+ mac_control = 0x20;
+ slaves = 2;
+ slave@0 {
+ slave_reg_ofs = 0x208;
+ sliver_reg_ofs = 0xd80;
+ phy_id = "davinci_mdio-0:00"
+ mac-address = [00 04 9F 01 1B B8];
+ };
+ slave@1 {
+ slave_reg_ofs = 0x208;
+ sliver_reg_ofs = 0xd80;
+ phy_id = "davinci_mdio-0:01"
+ mac-address = [00 04 9F 01 1B B9];
+ };
+ };
+

+
