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>

+* Samsung S3FWRN5 NCI NFC Controller
+
+Required properties:
+- compatible: Should be "samsung,s3fwrn5-i2c".
+- reg: address on the bus
+- interrupt-parent: phandle for the interrupt gpio controller
+- interrupts: GPIO interrupt to which the chip is connected
+- s3fwrn5,en-gpios: Output GPIO pin used for enabling/disabling the chip
+- s3fwrn5,fw-gpios: Output GPIO pin used to enter firmware mode and
+ sleep/wakeup control
+
+Example:
+
+&hsi2c_4 {
+ status = "okay";
+ s3fwrn5@27 {
+ compatible = "samsung,s3fwrn5-i2c";
+
+ reg = <0x27>;
+
+ interrupt-parent = <&gpa1>;
+ interrupts = <3 0 0>;
+
+ s3fwrn5,en-gpios = <&gpf1 4 0>;
+ s3fwrn5,fw-gpios = <&gpj0 2 0>;
+ };
