      1Freescale Reference Board Bindings
      2
      3This document describes device tree bindings for various devices that
      4exist on some Freescale reference boards.
      5
      6* Board Control and Status (BCSR)
      7
      8Required properties:
      9
     10 - compatible : Should be "fsl,<board>-bcsr"
     11 - reg : Offset and length of the register set for the device
     12
     13Example:
     14
     15	bcsr@f8000000 {
     16		compatible = "fsl,mpc8360mds-bcsr";
     17		reg = <f8000000 8000>;
     18	};
     19
     20* Freescale on-board FPGA
     21
     22This is the memory-mapped registers for on board FPGA.
     23
     24Required 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
     31Optional properties:
     32- interrupts: should specify event (wakeup) IRQ.
     33
     34Example (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
     43Example (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
     52Some Freescale boards like BSC9132QDS have on board FPGA connected on
     53the i2c bus.
     54
     55Required 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
     61Example:
     62	fpga: fpga@66 {
     63		compatible = "fsl,bsc9132qds-fpga", "fsl,fpga-qixis-i2c";
     64		reg = <0x66>;
     65	};
     66
     67* Freescale on-board CPLD
     68
     69Some Freescale boards like T1040RDB have an on board CPLD connected.
     70
     71Required 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
     77Example:
     78	cpld@3,0 {
     79		compatible = "fsl,t1040rdb-cpld";
     80		reg = <3 0 0x300>;
     81	};
