  1. Freescale Reference Board Bindings
  2.  
  3. This document describes device tree bindings for various devices that
  4. exist on some Freescale reference boards.
  5.  
  6. * Board Control and Status (BCSR)
  7.  
  8. Required properties:
  9.  
  10.  - compatible : Should be "fsl,<board>-bcsr"
  11.  - reg : Offset and length of the register set for the device
  12.  
  13. Example:
  14.  
  15.         bcsr@f8000000 {
  16.                 compatible = "fsl,mpc8360mds-bcsr";
  17.                 reg = <f8000000 8000>;
  18.         };
  19.  
  20. * Freescale on-board FPGA
  21.  
  22. This is the memory-mapped registers for on board FPGA.
  23.  
  24. Required properties:
  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.
  30.  
  31. Optional properties:
  32. - interrupts: should specify event (wakeup) IRQ.
  33.  
  34. Example (P1022DS):
  35.  
  36.          board-control@3,0 {
  37.                  compatible = "fsl,p1022ds-fpga", "fsl,fpga-ngpixis";
  38.                  reg = <3 0 0x30>;
  39.                  interrupt-parent = <&mpic>;
  40.                  interrupts = <8 8 0 0>;
  41.          };
  42.  
  43. Example (LS2080A-RDB):
  44.  
  45.         cpld@3,0 {
  46.                 compatible = "fsl,ls2080ardb-fpga", "fsl,fpga-qixis";
  47.                 reg = <0x3 0 0x10000>;
  48.         };
  49.  
  50. * Freescale on-board FPGA connected on I2C bus
  51.  
  52. Some Freescale boards like BSC9132QDS have on board FPGA connected on
  53. the i2c bus.
  54.  
  55. Required properties:
  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
  60.  
  61. Example:
  62.         fpga: fpga@66 {
  63.                 compatible = "fsl,bsc9132qds-fpga", "fsl,fpga-qixis-i2c";
  64.                 reg = <0x66>;
  65.         };
  66.  
  67. * Freescale on-board CPLD
  68.  
  69. Some Freescale boards like T1040RDB have an on board CPLD connected.
  70.  
  71. Required properties:
  72. - compatible: Should be a board-specific string like "fsl,<board>-cpld"
  73.   Example:
  74.         "fsl,t1040rdb-cpld", "fsl,t1042rdb-cpld", "fsl,t1042rdb_pi-cpld"
  75. - reg: should describe CPLD registers
  76.  
  77. Example:
  78.         cpld@3,0 {
  79.                 compatible = "fsl,t1040rdb-cpld";
  80.                 reg = <3 0 0x300>;
  81.         };
