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.

+Freescale i.MX6 On-Chip OTP Controller (OCOTP) device tree bindings

+- compatible: should be one of

+- reg: Should contain the register base and length.
+- clocks: Should contain a phandle pointing to the gated peripheral clock.
+
+Example:
+
+	ocotp: ocotp@021bc000 {
+		compatible = "fsl,imx6q-ocotp", "syscon";
+		reg = <0x021bc000 0x4000>;

+= NVMEM(Non Volatile Memory) Data Device Tree Bindings =
+
+This binding is intended to represent the location of hardware
+configuration data stored in NVMEMs like eeprom, efuses and so on.
+
+On a significant proportion of boards, the manufacturer has stored
+some data on NVMEM, for the OS to be able to retrieve these information
+and act upon it. Obviously, the OS has to know about where to retrieve
+these data from, and where they are stored on the storage device.
+
+This document is here to document this.
+
+= Data providers =
+Contains bindings specific to provider drivers and data cells as children
+of this node.
+
+Optional properties:
+ read-only: Mark the provider as read only.
+
+= Data cells =
+These are the child nodes of the provider which contain data cell
+information like offset and size in nvmem provider.
+
+Required properties:
+reg:	specifies the offset in byte within the storage device.
+
+Optional properties:
+
+bits:	Is pair of bit location and number of bits, which specifies offset
+	in bit and number of bits within the address range specified by reg property.
+	Offset takes values from 0-7.
+
+For example:
+
+	/* Provider */
+	qfprom: qfprom@00700000 {
+		...
+
+		/* Data cells */
+		tsens_calibration: calib@404 {
+			reg = <0x404 0x10>;

+			reg = <0x6 0x2>
+			bits = <7 2>
+		};

+			reg = <0xc 0x1>;

+

+	};
+
+= Data consumers =
+Are device nodes which consume nvmem data cells/providers.
+

+nvmem-cells: list of phandle to the nvmem data cells.
+nvmem-cell-names: names for the each nvmem-cells specified. Required if
+	nvmem-cells is used.
+
+Optional-properties:
+nvmem	: list of phandles to nvmem providers.
