The devices cover the whole range - of standard device types (network, serial, etc.) and miscellaneous - devices (gpio, LCD, spi, etc). Also, since these devices are - implemented within the fpga fabric every instance of the device can be - synthesised with different options that change the behaviour. - - Each IP-core has a set of parameters which the FPGA designer can use to - control how the core is synthesized. Historically, the EDK tool would - extract the device parameters relevant to device drivers and copy them - into an 'xparameters.h' in the form of #define symbols. This tells the - device drivers how the IP cores are configured, but it requres the kernel - to be recompiled every time the FPGA bitstream is resynthesized. - - The new approach is to export the parameters into the device tree and - generate a new device tree each time the FPGA bitstream changes. The - parameters which used to be exported as #defines will now become - properties of the device node. In general, device nodes for IP-cores - will take the following form: - - (name): (generic-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)>; - }; - - (generic-name): an open firmware-style name that describes the - generic class of device. Preferably, this is one word, such - as 'serial' or 'ethernet'. - (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 baseaddr parameter value (often named C_BASEADDR). - (HW_VER): from the HW_VER parameter. - (size): the address range size (often 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: serial@ec100000 { - device_type = "serial"; - compatible = "xlnx,opb-uartlite-1.00.b"; - reg = <ec100000 10000>; - interrupt-parent = <&opb_intc_0>; - 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. In - this case, the device should still describe the whole IP core with - a single node and add a child node for each logical device. The - ranges property can be used to translate from parent IP-core to the - registers of each device. In addition, the parent node should be - compatible with the bus type 'xlnx,compound', and should contain - #address-cells and #size-cells, as with any other bus. (Note: this - makes the assumption that both logical devices have the same bus - binding. 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. For example, the - following is the system.mhs entry for the dual ps2 controller found - on the ml403 reference design. - - BEGIN opb_ps2_dual_ref - PARAMETER INSTANCE = opb_ps2_dual_ref_0 - PARAMETER HW_VER = 1.00.a - PARAMETER C_BASEADDR = 0xA9000000 - PARAMETER C_HIGHADDR = 0xA9001FFF - BUS_INTERFACE SOPB = opb_v20_0 - PORT Sys_Intr1 = ps2_1_intr - PORT Sys_Intr2 = ps2_2_intr - PORT Clkin1 = ps2_clk_rx_1 - PORT Clkin2 = ps2_clk_rx_2 - PORT Clkpd1 = ps2_clk_tx_1 - PORT Clkpd2 = ps2_clk_tx_2 - PORT Rx1 = ps2_d_rx_1 - PORT Rx2 = ps2_d_rx_2 - PORT Txpd1 = ps2_d_tx_1 - PORT Txpd2 = ps2_d_tx_2 - END - - It would result in the following device tree nodes: - - opb_ps2_dual_ref_0: opb-ps2-dual-ref@a9000000 { - #address-cells = <1>; - #size-cells = <1>; - compatible = "xlnx,compound"; - ranges = <0 a9000000 2000>; - // If this device had extra parameters, then they would - // go here. - ps2@0 { - compatible = "xlnx,opb-ps2-dual-ref-1.00.a"; - reg = <0 40>; - interrupt-parent = <&opb_intc_0>; - interrupts = <3 0>; - cell-index = <0>; - }; - ps2@1000 { - compatible = "xlnx,opb-ps2-dual-ref-1.00.a"; - reg = <1000 40>; - interrupt-parent = <&opb_intc_0>; - interrupts = <3 0>; - cell-index = <0>; - }; - }; - - Also, the system.mhs file defines bus attachments from the processor - to the devices.

Some - implementations use a different resolution. - Default is <d#640 d#480> - - virt-resolution = <xvirt yvirt> : Size of framebuffer in memory. - Default is <d#1024 d#480>. - - rotate-display (empty) : rotate display 180 degrees. - - ii) Xilinx SystemACE - - The Xilinx SystemACE device is used to program FPGAs from an FPGA - bitstream stored on a CF card. 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. - - Required properties: - - current-speed : Baud rate of uartlite - - v) Xilinx hwicap - - Xilinx hwicap devices provide access to the configuration logic - of the FPGA through the Internal Configuration Access Port - (ICAP). The ICAP enables partial reconfiguration of the FPGA, - readback of the configuration information, and some control over - 'warm boots' of the FPGA fabric. - - Required properties: - - xlnx,family : The family of the FPGA, necessary since the - capabilities of the underlying ICAP hardware - differ between different families. May be - 'virtex2p', 'virtex4', or 'virtex5'. - - vi) Xilinx Uart 16550 - - Xilinx UART 16550 devices are very similar to the NS16550 but with - different register spacing and an offset from the base address. - - Required properties: - - clock-frequency : Frequency of the clock input - - reg-offset : A value of 3 is required - - reg-shift : A value of 2 is required - - e) USB EHCI controllers - - Required properties: - - compatible : should be "usb-ehci". - - reg : should contain at least address and length of the standard EHCI - register set for the device. Optional platform-dependent registers - (debug-port or other) can be also specified here, but only after - definition of standard EHCI registers. - - interrupts : one EHCI interrupt should be described here. - If device registers are implemented in big endian mode, the device - node should have "big-endian-regs" property. - If controller implementation operates with big endian descriptors, - "big-endian-desc" property should be specified. - If both big endian registers and descriptors are used by the controller - implementation, "big-endian" property can be specified instead of having - both "big-endian-regs" and "big-endian-desc". - - Example (Sequoia 440EPx): - ehci@e0000300 { - compatible = "ibm,usb-ehci-440epx", "usb-ehci"; - interrupt-parent = <&UIC0>; - interrupts = <1a 4>; - reg = <0 e0000300 90 0 e0000390 70>; - big-endian; - }; - - f) MDIO on GPIOs - - Currently defined compatibles: - - virtual,gpio-mdio - - MDC and MDIO lines connected to GPIO controllers are listed in the - gpios property as described in section VIII.1 in the following order: - - MDC, MDIO. - - Example: - - mdio { - compatible = "virtual,mdio-gpio"; - #address-cells = <1>; - #size-cells = <0>; - gpios = <&qe_pio_a 11 - &qe_pio_c 6>; - }; - - g) SPI (Serial Peripheral Interface) busses - - SPI busses can be described with a node for the SPI master device - and a set of child nodes for each SPI slave on the bus. For this - discussion, it is assumed that the system's SPI controller is in - SPI master mode. This binding does not describe SPI controllers - in slave mode. - - The SPI master node requires the following properties: - - #address-cells - number of cells required to define a chip select - address on the SPI bus. - - #size-cells - should be zero. - - compatible - name of SPI bus controller following generic names - recommended practice. - No other properties are required in the SPI bus node. It is assumed - that a driver for an SPI bus device will understand that it is an SPI bus. - However, the binding does not attempt to define the specific method for - assigning chip select numbers. Since SPI chip select configuration is - flexible and non-standardized, it is left out of this binding with the - assumption that board specific platform code will be used to manage - chip selects. Individual drivers can define additional properties to - support describing the chip select layout. - - SPI slave nodes must be children of the SPI master node and can - contain the following properties. - - reg - (required) chip select address of device. - - compatible - (required) name of SPI device following generic names - recommended practice - - spi-max-frequency - (required) Maximum SPI clocking speed of device in Hz - - spi-cpol - (optional) Empty property indicating device requires - inverse clock polarity (CPOL) mode - - spi-cpha - (optional) Empty property indicating device requires - shifted clock phase (CPHA) mode - - spi-cs-high - (optional) Empty property indicating device requires - chip select active high - - SPI example for an MPC5200 SPI bus: - spi@f00 { - #address-cells = <1>; - #size-cells = <0>; - compatible = "fsl,mpc5200b-spi","fsl,mpc5200-spi"; - reg = <0xf00 0x20>; - interrupts = <2 13 0 2 14 0>; - interrupt-parent = <&mpc5200_pic>; - - ethernet-switch@0 { - compatible = "micrel,ks8995m"; - spi-max-frequency = <1000000>; - reg = <0>; - }; - - codec@1 { - compatible = "ti,tlv320aic26"; - spi-max-frequency = <100000>; - reg = <1>; - }; - }; - -VII - Marvell Discovery mv64[345]6x System Controller chips -=========================================================== - -The Marvell mv64[345]60 series of system controller chips contain -many of the peripherals needed to implement a complete computer -system.
