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 properties: |
|
- compatible: should be a board-specific string followed by a string |
|
indicating the type of FPGA. Example: |
|
"fsl,<board>-fpga", "fsl,fpga-pixis", or |
|
"fsl,<board>-fpga", "fsl,fpga-qixis" |
|
- reg: should contain the address and the length of the FPGA register set. |
|
|
|
Optional properties: |
|
- 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>; |
|
}; |
|
|
|
Example (LS2080A-RDB): |
|
|
|
cpld@3,0 { |
|
compatible = "fsl,ls2080ardb-fpga", "fsl,fpga-qixis"; |
|
reg = <0x3 0 0x10000>; |
|
}; |
|
|
|
* 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>; |
|
};
|
