   1 * Board Control and Status (BCSR)
   2
   3 Required properties:
   4
   5  - compatible : Should be "fsl,<board>-bcsr"
   6  - reg : Offset and length of the register set for the device
   7
   8 Example:
   9
  10         bcsr@f8000000 {
  11                 compatible = "fsl,mpc8360mds-bcsr";
  12                 reg = <f8000000 8000>;
  13         };
  14
  15 * Freescale on board FPGA
  16
  17 This is the memory-mapped registers for on board FPGA.
  18
  19 Required properities:
  20 - compatible : should be "fsl,fpga-pixis".
  21 - reg : should contain the address and the length of the FPPGA register
  22   set.
  23 - interrupt-parent: should specify phandle for the interrupt controller.
  24 - interrupts : should specify event (wakeup) IRQ.
  25
  26 Example (MPC8610HPCD):
  27
  28         board-control@e8000000 {
  29                 compatible = "fsl,fpga-pixis";
  30                 reg = <0xe8000000 32>;
  31                 interrupt-parent = <&mpic>;
  32                 interrupts = <8 8>;
  33         };
  34
  35 * Freescale BCSR GPIO banks
  36
  37 Some BCSR registers act as simple GPIO controllers, each such
  38 register can be represented by the gpio-controller node.
  39
  40 Required properities:
  41 - compatible : Should be "fsl,<board>-bcsr-gpio".
  42 - reg : Should contain the address and the length of the GPIO bank
  43   register.
  44 - #gpio-cells : Should be two. The first cell is the pin number and the
  45   second cell is used to specify optional parameters (currently unused).
  46 - gpio-controller : Marks the port as GPIO controller.
  47
  48 Example:
  49
  50         bcsr@1,0 {
  51                 #address-cells = <1>;
  52                 #size-cells = <1>;
  53                 compatible = "fsl,mpc8360mds-bcsr";
  54                 reg = <1 0 0x8000>;
  55                 ranges = <0 1 0 0x8000>;
  56
  57                 bcsr13: gpio-controller@d {
  58                         #gpio-cells = <2>;
  59                         compatible = "fsl,mpc8360mds-bcsr-gpio";
  60                         reg = <0xd 1>;
  61                         gpio-controller;
  62                 };
  63         };
