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>

+* Melexis MLX90614 contactless IR temperature sensor
+
+http://melexis.com/Infrared-Thermometer-Sensors/Infrared-Thermometer-Sensors/MLX90614-615.aspx
+
+Required properties:
+
+ - compatible: should be "melexis,mlx90614"
+ - reg: the I2C address of the sensor
+
+Optional properties:
+
+ - wakeup-gpios: device tree identifier of the GPIO connected to the SDA line
+ to hold low in order to wake up the device. In normal operation, the
+ GPIO is set as input and will not interfere in I2C communication. There
+ is no need for a GPIO driving the SCL line. If no GPIO is given, power
+ management is disabled.
+
+Example:
+
+mlx90614@5a {
+ compatible = "melexis,mlx90614";
+ reg = <0x5a>;
+ wakeup-gpios = <&gpio0 2 GPIO_ACTIVE_HIGH>;
+};
