1 Freescale Reference Board Bindings
3 This document describes device tree bindings for various devices that
4 exist on some Freescale reference boards.
6 * Board Control and Status (BCSR)
10 - compatible : Should be "fsl,<board>-bcsr"
11 - reg : Offset and length of the register set for the device
16 compatible = "fsl,mpc8360mds-bcsr";
17 reg = <f8000000 8000>;
20 * Freescale on-board FPGA
22 This is the memory-mapped registers for on board FPGA.
25 - compatible: should be a board-specific string followed by a string
26 indicating the type of FPGA. Example:
27 "fsl,<board>-fpga", "fsl,fpga-pixis", or
28 "fsl,<board>-fpga", "fsl,fpga-qixis"
29 - reg: should contain the address and the length of the FPGA register set.
32 - interrupts: should specify event (wakeup) IRQ.
37 compatible = "fsl,p1022ds-fpga", "fsl,fpga-ngpixis";
39 interrupt-parent = <&mpic>;
40 interrupts = <8 8 0 0>;
43 Example (LS2080A-RDB):
46 compatible = "fsl,ls2080ardb-fpga", "fsl,fpga-qixis";
47 reg = <0x3 0 0x10000>;
50 * Freescale on-board FPGA connected on I2C bus
52 Some Freescale boards like BSC9132QDS have on board FPGA connected on
56 - compatible: Should be a board-specific string followed by a string
57 indicating the type of FPGA. Example:
58 "fsl,<board>-fpga", "fsl,fpga-qixis-i2c"
59 - reg: Should contain the address of the FPGA
63 compatible = "fsl,bsc9132qds-fpga", "fsl,fpga-qixis-i2c";
67 * Freescale on-board CPLD
69 Some Freescale boards like T1040RDB have an on board CPLD connected.
72 - compatible: Should be a board-specific string like "fsl,<board>-cpld"
74 "fsl,t1040rdb-cpld", "fsl,t1042rdb-cpld", "fsl,t1042rdb_pi-cpld"
75 - reg: should describe CPLD registers
79 compatible = "fsl,t1040rdb-cpld";
