Subject: [PATCH v2 1/2] dt-bindings: clock: xilinx: Convert VCU bindings to dtschema

From: Rohit Visavalia <rohit.visavalia@...inx.com>

Convert AMD (Xilinx) VCU bindings to yaml format.
Additional changes:
   - move xlnx_vcu DT binding to clock from soc following commit
     a2fe7baa27a4 ("clk: xilinx: move xlnx_vcu clock driver from soc")
   - corrected clock sequence as per xilinx device-tree generator

Signed-off-by: Rohit Visavalia <rohit.visavalia@...inx.com>

---
Changes in v2:
  - dropped patch 1 and move the file during conversion
  - dropped description in schema
  - updated commit msg for change in clock ordering

-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 : The base offset and size of the VCU_PL_SLCR register space.
-- 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@...40000 {
-		compatible = "xlnx,vcu-logicoreip-1.0";
-		reg = <0x0 0xa0040000 0x0 0x1000>;
-		clocks = <&si570_1>, <&clkc 71>;
-		clock-names = "pll_ref", "aclk";
-	};
