+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";
+ };
