You can -dynamically create a new interface by saying 'mkdir /proc/comx/comx0' (or you -can name it whatever you want up to 8 characters long, comx[n] is just a -convention). -Generally the files contained in these directories are text files, which can -be viewed by 'cat filename' and you can write a string to such a file by -saying 'echo _string_ >filename'. This is very similar to the sysctl interface. -Don't use a text editor to edit these files, always use 'echo' (or 'cat' -where appropriate). -When you've created the comx[n] directory, two files are created automagically -in it: 'boardtype' and 'protocol'. You have to fill in these files correctly -for your board and protocol you intend to use (see the board and protocol -descriptions in this file below or the example scripts in the 'etc' directory). -After filling in these files, other files will appear in the directory for -setting the various hardware- and protocol-related informations (for example -irq and io addresses, keepalive values etc.) These files are set to default -values upon creation, so you don't necessarily have to change all of them. - -When you're ready with filling in the files in the comx[n] directory, you can -configure the corresponding network interface with the standard network -configuration utilities.

Specify 'frad' as protocol type. -Now you can bring this interface up by saying 'ifconfig comx0 up' (or whatever -you've named the interface). Do not assign any IP address to this interface -and do not set any routes through it. -Then, set up your DLCIs the following way: create a comx interface for each -DLCI you intend to use (with mkdir), and write 'dlci' to the 'boardtype' file, -and 'ietf-ip' to the 'protocol' file. Currently, the only supported -encapsulation type is this (also called as RFC1294/1490 IP encapsulation). -Write the DLCI number to the 'dlci' file, and write the name of the physical -COMX device to the file called 'master'. -Now you can assign an IP address to this interface and set routes using it. -See the example file for further info and example config script. -Notes: this driver implements a DTE interface with partially implemented -Q933a LMI. -You can find an extensively commented example in the 'etc' directory. - -FURTHER /proc FILES - -boardtype: -Type of the hardware.

In general, device nodes for IP-cores + will take the following form: + + (name)@(base-address) { + compatible = "xlnx,(ip-core-name)-(HW_VER)" + [, (list of compatible devices), ...]; + reg = <(baseaddr) (size)>; + interrupt-parent = <&interrupt-controller-phandle>; + interrupts = < ... >; + xlnx,(parameter1) = "(string-value)"; + xlnx,(parameter2) = <(int-value)>; + }; + + (ip-core-name): the name of the ip block (given after the BEGIN + directive in system.mhs). Should be in lowercase + and all underscores '_' converted to dashes '-'. + (name): is derived from the "PARAMETER INSTANCE" value. + (parameter#): C_* parameters from system.mhs. The C_ prefix is + dropped from the parameter name, the name is converted + to lowercase and all underscore '_' characters are + converted to dashes '-'. + (baseaddr): the C_BASEADDR parameter. + (HW_VER): from the HW_VER parameter. + (size): equals C_HIGHADDR - C_BASEADDR + 1 + + Typically, the compatible list will include the exact IP core version + followed by an older IP core version which implements the same + interface or any other device with the same interface. + + 'reg', 'interrupt-parent' and 'interrupts' are all optional properties. + + For example, the following block from system.mhs: + + BEGIN opb_uartlite + PARAMETER INSTANCE = opb_uartlite_0 + PARAMETER HW_VER = 1.00.b + PARAMETER C_BAUDRATE = 115200 + PARAMETER C_DATA_BITS = 8 + PARAMETER C_ODD_PARITY = 0 + PARAMETER C_USE_PARITY = 0 + PARAMETER C_CLK_FREQ = 50000000 + PARAMETER C_BASEADDR = 0xEC100000 + PARAMETER C_HIGHADDR = 0xEC10FFFF + BUS_INTERFACE SOPB = opb_7 + PORT OPB_Clk = CLK_50MHz + PORT Interrupt = opb_uartlite_0_Interrupt + PORT RX = opb_uartlite_0_RX + PORT TX = opb_uartlite_0_TX + PORT OPB_Rst = sys_bus_reset_0 + END + + becomes the following device tree node: + + opb-uartlite-0@ec100000 { + device_type = "serial"; + compatible = "xlnx,opb-uartlite-1.00.b"; + reg = <ec100000 10000>; + interrupt-parent = <&opb-intc>; + interrupts = <1 0>; // got this from the opb_intc parameters + current-speed = <d#115200>; // standard serial device prop + clock-frequency = <d#50000000>; // standard serial device prop + xlnx,data-bits = <8>; + xlnx,odd-parity = <0>; + xlnx,use-parity = <0>; + }; + + Some IP cores actually implement 2 or more logical devices.

If this is not true, then separate nodes should be used for + each logical device). The 'cell-index' property can be used to enumerate + logical devices within an IP core.

It can also be used as a generic CF + interface device. + + Optional properties: + - 8-bit (empty) : Set this property for SystemACE in 8 bit mode + + iii) Xilinx EMAC and Xilinx TEMAC + + Xilinx Ethernet devices. In addition to general xilinx properties + listed above, nodes for these devices should include a phy-handle + property, and may include other common network device properties + like local-mac-address. + + iv) Xilinx Uartlite + + Xilinx uartlite devices are simple fixed speed serial ports. + + Requred properties: + - current-speed : Baud rate of uartlite + More devices will be defined as this spec matures.
