PNI RM3100 is a high resolution, large signal immunity magnetometer,
composed of 3 single sensors and a processing chip with MagI2C Interface.
PNI is not in the vendors' list, so this patch is also adding it.

+* PNI RM3100 3-axis magnetometer sensor
+
+Required properties:
+
+- compatible : should be "pni,rm3100"
+- reg : the I2C address or SPI chip select number of the sensor.
+
+Optional properties:
+
+- interrupts: data ready (DRDY) from the chip.
+ The interrupts can be triggered on rising edges.
+
+Example:
+
+rm3100: rm3100@20 {
+ compatible = "pni,rm3100";
+ reg = <0x20>;
+ interrupt-parent = <&gpio0>;
+ interrupts = <4 IRQ_TYPE_EDGE_RISING>;
+};
