0001 Freescale Reference Board Bindings
0002
0003 This document describes device tree bindings for various devices that
0004 exist on some Freescale reference boards.
0005
0006 * Board Control and Status (BCSR)
0007
0008 Required properties:
0009
0010 - compatible : Should be "fsl,<board>-bcsr"
0011 - reg : Offset and length of the register set for the device
0012
0013 Example:
0014
0015 bcsr@f8000000 {
0016 compatible = "fsl,mpc8360mds-bcsr";
0017 reg = <f8000000 8000>;
0018 };
0019
0020 * Freescale on-board FPGA
0021
0022 This is the memory-mapped registers for on board FPGA.
0023
0024 Required properties:
0025 - compatible: should be a board-specific string followed by a string
0026 indicating the type of FPGA. Example:
0027 "fsl,<board>-fpga", "fsl,fpga-pixis", or
0028 "fsl,<board>-fpga", "fsl,fpga-qixis"
0029 - reg: should contain the address and the length of the FPGA register set.
0030
0031 Optional properties:
0032 - interrupts: should specify event (wakeup) IRQ.
0033
0034 Example (P1022DS):
0035
0036 board-control@3,0 {
0037 compatible = "fsl,p1022ds-fpga", "fsl,fpga-ngpixis";
0038 reg = <3 0 0x30>;
0039 interrupt-parent = <&mpic>;
0040 interrupts = <8 8 0 0>;
0041 };
0042
0043 Example (LS2080A-RDB):
0044
0045 cpld@3,0 {
0046 compatible = "fsl,ls2080ardb-fpga", "fsl,fpga-qixis";
0047 reg = <0x3 0 0x10000>;
0048 };
0049
0050 * Freescale on-board FPGA connected on I2C bus
0051
0052 Some Freescale boards like BSC9132QDS have on board FPGA connected on
0053 the i2c bus.
0054
0055 Required properties:
0056 - compatible: Should be a board-specific string followed by a string
0057 indicating the type of FPGA. Example:
0058 "fsl,<board>-fpga", "fsl,fpga-qixis-i2c"
0059 - reg: Should contain the address of the FPGA
0060
0061 Example:
0062 fpga: fpga@66 {
0063 compatible = "fsl,bsc9132qds-fpga", "fsl,fpga-qixis-i2c";
0064 reg = <0x66>;
0065 };
0066
0067 * Freescale on-board CPLD
0068
0069 Some Freescale boards like T1040RDB have an on board CPLD connected.
0070
0071 Required properties:
0072 - compatible: Should be a board-specific string like "fsl,<board>-cpld"
0073 Example:
0074 "fsl,t1040rdb-cpld", "fsl,t1042rdb-cpld", "fsl,t1042rdb_pi-cpld"
0075 - reg: should describe CPLD registers
0076
0077 Example:
0078 cpld@3,0 {
0079 compatible = "fsl,t1040rdb-cpld";
0080 reg = <3 0 0x300>;
0081 };
