Freescale Reference Board Bindings This document describes device tree bindings for various devices that exist on some Freescale reference boards. * Board Control and Status (BCSR) Required properties: - compatible : Should be "fsl,<board>-bcsr" - reg : Offset and length of the register set for the device Example: bcsr@f8000000 { compatible = "fsl,mpc8360mds-bcsr"; reg = <f8000000 8000>; }; * Freescale on-board FPGA This is the memory-mapped registers for on board FPGA. Required properties: - compatible: should be a board-specific string followed by a string indicating the type of FPGA. Example: "fsl,<board>-fpga", "fsl,fpga-pixis", or "fsl,<board>-fpga", "fsl,fpga-qixis" - reg: should contain the address and the length of the FPGA register set. Optional properties: - interrupts: should specify event (wakeup) IRQ. Example (P1022DS): board-control@3,0 { compatible = "fsl,p1022ds-fpga", "fsl,fpga-ngpixis"; reg = <3 0 0x30>; interrupt-parent = <&mpic>; interrupts = <8 8 0 0>; }; Example (LS2080A-RDB): cpld@3,0 { compatible = "fsl,ls2080ardb-fpga", "fsl,fpga-qixis"; reg = <0x3 0 0x10000>; }; * Freescale on-board FPGA connected on I2C bus Some Freescale boards like BSC9132QDS have on board FPGA connected on the i2c bus. Required properties: - compatible: Should be a board-specific string followed by a string indicating the type of FPGA. Example: "fsl,<board>-fpga", "fsl,fpga-qixis-i2c" - reg: Should contain the address of the FPGA Example: fpga: fpga@66 { compatible = "fsl,bsc9132qds-fpga", "fsl,fpga-qixis-i2c"; reg = <0x66>; }; * Freescale on-board CPLD Some Freescale boards like T1040RDB have an on board CPLD connected. Required properties: - compatible: Should be a board-specific string like "fsl,<board>-cpld" Example: "fsl,t1040rdb-cpld", "fsl,t1042rdb-cpld", "fsl,t1042rdb_pi-cpld" - reg: should describe CPLD registers Example: cpld@3,0 { compatible = "fsl,t1040rdb-cpld"; reg = <3 0 0x300>; };
