These changes are the raw update to linux-4.4.6-rt14. Kernel sources

are taken from kernel.org, and rt patch from the rt wiki download page.

During the rebasing, the following patch collided:

Force tick interrupt and get rid of softirq magic(I70131fb85).

Collisions have been removed because its logic was found on the
source already.

+Xilinx Zynq Reset Manager
+
+The Zynq AP-SoC has several different resets.
+
+See Chapter 26 of the Zynq TRM (UG585) for more information about Zynq resets.
+
+Required properties:
+- compatible: "xlnx,zynq-reset"
+- reg: SLCR offset and size taken via syscon <0x200 0x48>
+- syscon: <&slcr>
+  This should be a phandle to the Zynq's SLCR registers.
+- #reset-cells: Must be 1
+
+The Zynq Reset Manager needs to be a childnode of the SLCR.
+
+Example:
+	rstc: rstc@200 {
+		compatible = "xlnx,zynq-reset";
+		reg = <0x200 0x48>;
+		#reset-cells = <1>;
+		syscon = <&slcr>;
