v7:
Combined the patch for deletion and add of the driver
dropping the ack from Greg for the staging as it is a combined patch.
Add vendor prefix to speedgrade
v8:

-TODO:
- - support for fractional multiplier
- - support for fractional divider (output 0 only)
- - support for set_rate() operations (may benefit from Stephen Boyd's
- refactoring of the clk primitives: https://lkml.org/lkml/2014/9/5/766)
- - review arithmetic
- - overflow after multiplication?
- - maximize accuracy before divisions

-Binding for Xilinx Clocking Wizard IP Core
-
-This binding uses the common clock binding[1]. Details about the devices can be
-found in the product guide[2].
-
-[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
-[2] Clocking Wizard Product Guide
-https://www.xilinx.com/support/documentation/ip_documentation/clk_wiz/v5_1/pg065-clk-wiz.pdf
-
-Required properties:
- - compatible: Must be 'xlnx,clocking-wizard'
- - reg: Base and size of the cores register space
- - clocks: Handle to input clock
- - clock-names: Tuple containing 'clk_in1' and 's_axi_aclk'
- - clock-output-names: Names for the output clocks
-
-Optional properties:
- - speed-grade: Speed grade of the device (valid values are 1..3)
-
-Example:
- clock-generator@40040000 {
- reg = <0x40040000 0x1000>;
- compatible = "xlnx,clocking-wizard";
- speed-grade = <1>;
- clock-names = "clk_in1", "s_axi_aclk";
- clocks = <&clkc 15>, <&clkc 15>;
- clock-output-names = "clk_out0", "clk_out1", "clk_out2",
- "clk_out3", "clk_out4", "clk_out5",
- "clk_out6", "clk_out7";
- };
