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"
28 - reg: should contain the address and the length of the FPGA register set.
29 - interrupt-parent: should specify phandle for the interrupt controller.
30 - interrupts: should specify event (wakeup) IRQ.
35 compatible = "fsl,p1022ds-fpga", "fsl,fpga-ngpixis";
37 interrupt-parent = <&mpic>;
38 interrupts = <8 8 0 0>;
41 * Freescale BCSR GPIO banks
43 Some BCSR registers act as simple GPIO controllers, each such
44 register can be represented by the gpio-controller node.
47 - compatible : Should be "fsl,<board>-bcsr-gpio".
48 - reg : Should contain the address and the length of the GPIO bank
50 - #gpio-cells : Should be two. The first cell is the pin number and the
51 second cell is used to specify optional parameters (currently unused).
52 - gpio-controller : Marks the port as GPIO controller.
59 compatible = "fsl,mpc8360mds-bcsr";
61 ranges = <0 1 0 0x8000>;
63 bcsr13: gpio-controller@d {
65 compatible = "fsl,mpc8360mds-bcsr-gpio";
