-Freescale Reference Board Bindings
-
-This document describes device tree bindings for various devices that
-exist on some Freescale reference boards.
-
-* Board Control and Status (BCSR)
-
-Required properties:
-
- - compatible : Should be "fsl,<board>-bcsr"
- - reg : Offset and length of the register set for the device
-
-Example:
-
- bcsr@f8000000 {
- compatible = "fsl,mpc8360mds-bcsr";
- reg = <f8000000 8000>;
- };
-
-* Freescale on-board FPGA
-
-This is the memory-mapped registers for on board FPGA.
-
-Required properities:
-- compatible: should be a board-specific string followed by a string
- indicating the type of FPGA. Example:
- "fsl,<board>-fpga", "fsl,fpga-pixis"
-- reg: should contain the address and the length of the FPGA register set.
-- interrupt-parent: should specify phandle for the interrupt controller.
-- interrupts: should specify event (wakeup) IRQ.
-
-Example (P1022DS):
-
- board-control@3,0 {
- compatible = "fsl,p1022ds-fpga", "fsl,fpga-ngpixis";
- reg = <3 0 0x30>;
- interrupt-parent = <&mpic>;
- interrupts = <8 8 0 0>;
- };
-
-* Freescale BCSR GPIO banks
-
-Some BCSR registers act as simple GPIO controllers, each such
-register can be represented by the gpio-controller node.
-
-Required properities:
-- compatible : Should be "fsl,<board>-bcsr-gpio".
-- reg : Should contain the address and the length of the GPIO bank
- register.
-- #gpio-cells : Should be two. The first cell is the pin number and the
- second cell is used to specify optional parameters (currently unused).
-- gpio-controller : Marks the port as GPIO controller.
-
-Example:
-
- bcsr@1,0 {
- #address-cells = <1>;
- #size-cells = <1>;
- compatible = "fsl,mpc8360mds-bcsr";
- reg = <1 0 0x8000>;
- ranges = <0 1 0 0x8000>;
-
- bcsr13: gpio-controller@d {
- #gpio-cells = <2>;
- compatible = "fsl,mpc8360mds-bcsr-gpio";
- reg = <0xd 1>;
- gpio-controller;
- };
- };
-
-* Freescale on-board FPGA connected on I2C bus
-
-Some Freescale boards like BSC9132QDS have on board FPGA connected on
-the i2c bus.
-
-Required properties:
-- compatible: Should be a board-specific string followed by a string
- indicating the type of FPGA. Example:
- "fsl,<board>-fpga", "fsl,fpga-qixis-i2c"
-- reg: Should contain the address of the FPGA
-
-Example:
- fpga: fpga@66 {
- compatible = "fsl,bsc9132qds-fpga", "fsl,fpga-qixis-i2c";
- reg = <0x66>;
- };
-
-* Freescale on-board CPLD
-
-Some Freescale boards like T1040RDB have an on board CPLD connected.
-
-Required properties:
-- compatible: Should be a board-specific string like "fsl,<board>-cpld"
- Example:
- "fsl,t1040rdb-cpld", "fsl,t1042rdb-cpld", "fsl,t1042rdb_pi-cpld"
-- reg: should describe CPLD registers
-
-Example:
- cpld@3,0 {
- compatible = "fsl,t1040rdb-cpld";
- reg = <3 0 0x300>;
- };
