+* MOXA ART Interrupt Controller
+
+MOXA ART Interrupt Controller (moxart-interrupt-controller) is used on
+MOXA ART SoCs and supports 32 non-configurable number of interrupts
+
+Main node required properties:
+
+- compatible : should be:
+ "moxa,moxart-interrupt-controller"
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt source. The type shall be a <u32> and the value shall be 2.
+
+ The first cell contains the interrupt number in the range [0-31].
+ The second cell contains the interrupt type
+- reg: physical base address and size of the intc registers map.
+- interrupt-mask: Specifies if the interrupt is edge or level-triggered
+ each bit represent an interrupt 0-31 where 1 signify edge
+
+Example:
+
+ intc: interrupt-controller at 98800000 {
+ compatible = "moxa,moxart-interrupt-controller";
+ reg = <0x98800000 0x38>;
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ interrupt-mask = <0x00080000>;
+ };

+MOXA ART timer
+-----------------------------------------------------
+This timer is used on MOXA ART SoCs:
+
+Required properties:
+- compatible : "moxa,moxart-timer"

+Example:

+ reg = <0x98400000 0x10>;
