LogicoreIP designed compatible with Xilinx ZYNQ family.

-------------------------------------------------------

|
|
General concept
|
|
---------------
|
|
|
|
LogicoreIP design to provide the isolation between processing system
|
|
and programmable logic. Also provides the list of register set to configure
|
|
the frequency.
|
|
|
|
Required properties:
|
|
- compatible: shall be one of:
|
|
"xlnx,vcu"
|
|
"xlnx,vcu-logicoreip-1.0"
|
|
- reg, reg-names: There are two sets of registers need to provide.
|
|
1. vcu slcr
|
|
2. Logicore
|
|
reg-names should contain name for the each register sequence.
|
|
- clocks: phandle for aclk and pll_ref clocksource
|
|
- clock-names: The identification string, "aclk", is always required for
|
|
the axi clock. "pll_ref" is required for pll.
|
|
Example:
|
|
|
|
xlnx_vcu: vcu@a0040000 {
|
|
compatible = "xlnx,vcu-logicoreip-1.0";
|
|
reg = <0x0 0xa0040000 0x0 0x1000>,
|
|
<0x0 0xa0041000 0x0 0x1000>;
|
|
reg-names = "vcu_slcr", "logicore";
|
|
clocks = <&si570_1>, <&clkc 71>;
|
|
clock-names = "pll_ref", "aclk";
|
|
};
