Added the txt file which contain the xlnx,vcu DT node
properties information. This also provides the information
of it's child node as well.

+Xilinx VCU init Driver
+-----------------------------
+
+General concept
+---------------
+
+Xilinx VCU init driver is developed to handle the LogiCore related
+new implementation. In this directory, The DT node of the Xilinx
+VCU init driver represents as a top level node.
+
+Required properties:
+- compatible: Must be "xlnx,vcu".
+- 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.
+- ranges
+- VCU Init driver node define the following child nodes:
+ * Allegro encoder driver node
+ - compatible: Must be "al,al5e"
+ - reg: There is a one set of register.
+ - interrupts: interrupt number to the cpu.
+ - interrupt-parent: the phandle for the interrupt controller
+ that services interrupts for this device.
+ * Allegro decoder driver node
+ - compatible: Must be "al,al5d"
+ - reg: There is a one set of register.
+ - interrupts: interrupt number to the cpu.
+ - interrupt-parent: the phandle for the interrupt controller
+ that services interrupts for this device.
+Example:
+
+ xlnx_vcu: vcu@a0040000 {
+ compatible = "xlnx,vcu";
+ #address-cells = <2>;
+ #size-cells = <2>;
+ reg = <0x0 0xa0040000 0x0 0x1000>,
+ <0x0 0xa0041000 0x0 0x1000>;
+ reg-names = "vcu_slcr", "logicore";
+ clocks = <&si570_1>, <&clkc 71>;
+ clock-names = "pll_ref", "aclk";
+ ranges;
+ encoder: al5e@a0000000 {
+ compatible = "al,al5e";
+ reg = <0x0 0xa0000000 0x0 0x10000>;
+ interrupts = <0 89 4>;
+ interrupt-parent = <&gic>;
+ };
+
+ decoder: al5d@a0020000 {
+ compatible = "al,al5d";
+ reg = <0x0 0xa0020000 0x0 0x10000>;
+ interrupts = <0 89 4>;
+ interrupt-parent = <&gic>;
+ };
+ };
