Xilinx Zynq Reset Manager
|
|
|
|
The Zynq AP-SoC has several different resets.
|
|
|
|
See Chapter 26 of the Zynq TRM (UG585) for more information about Zynq resets.
|
|
|
|
Required properties:
|
|
- compatible: "xlnx,zynq-reset"
|
|
- reg: SLCR offset and size taken via syscon <0x200 0x48>
|
|
- syscon: <&slcr>
|
|
This should be a phandle to the Zynq's SLCR registers.
|
|
- #reset-cells: Must be 1
|
|
|
|
The Zynq Reset Manager needs to be a childnode of the SLCR.
|
|
|
|
Example:
|
|
rstc: rstc@200 {
|
|
compatible = "xlnx,zynq-reset";
|
|
reg = <0x200 0x48>;
|
|
#reset-cells = <1>;
|
|
syscon = <&slcr>;
|
|
};
|
|
|
|
