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.

+UniPhier UART controller
+
+Required properties:
+- compatible: should be "socionext,uniphier-uart".
+- reg: offset and length of the register set for the device.
+- interrupts: a single interrupt specifier.
+- clocks: phandle to the input clock.
+
+Optional properties:
+- fifo-size: the RX/TX FIFO size.  Defaults to 64 if not specified.
+
+Example:
+	aliases {
+		serial0 = &serial0;
+	};
+
+	serial0: serial@54006800 {
+		compatible = "socionext,uniphier-uart";
+		reg = <0x54006800 0x40>;
+		interrupts = <0 33 4>;
+		clocks = <&uart_clk>;
+		fifo-size = <64>;
+	};
