* 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 "fsl,fpga-pixis".
- reg : should contain the address and the length of the FPPGA register
set.
Example (MPC8610HPCD):
board-control@e8000000 {
compatible = "fsl,fpga-pixis";
reg = <0xe8000000 32>;
};
* 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;
};
};
