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. Change-Id: I7f57a4081d9deaa0d9ccfc41a6c8daccdee3b769 Signed-off-by: José Pekkarinen <jose.pekkarinen@nokia.com>

+Xilinx Zynq UltraScale+ MPSoC GQSPI controller Device Tree Bindings
+-------------------------------------------------------------------
+
+Required properties:
+- compatible : Should be "xlnx,zynqmp-qspi-1.0".
+- reg : Physical base address and size of GQSPI registers map.
+- interrupts : Property with a value describing the interrupt
+ number.
+- interrupt-parent : Must be core interrupt controller.
+- clock-names : List of input clock names - "ref_clk", "pclk"
+ (See clock bindings for details).
+- clocks : Clock phandles (see clock bindings for details).
+
+Optional properties:
+- num-cs : Number of chip selects used.
+
+Example:
+ qspi: spi@ff0f0000 {
+ compatible = "xlnx,zynqmp-qspi-1.0";
+ clock-names = "ref_clk", "pclk";
+ clocks = <&misc_clk &misc_clk>;
+ interrupts = <0 15 4>;
+ interrupt-parent = <&gic>;
+ num-cs = <1>;
+ reg = <0x0 0xff0f0000 0x1000>,<0x0 0xc0000000 0x8000000>;
+ };
