+DT bindings for the I/O DATA HDL-U interrupt controller
+
+Required properties:
+
+  - compatible: has to be "iodata,landisk-intc".
+
+  - reg: Base address and length of interrupt controller register.
+
+  - interrupt-controller: Identifies the node as an interrupt controller.
+
+  - #interrupt-cells: has to be <1>: an interrupt index.
+
+  - interrupt-map: Interrupt mapping on parent controller.

interrupt-controller and interrupt-map are supposed to be mutually 
exclusive, so you should probably drop interrupt-controller.

Yes. This logic is not interrupt controller.
Remove this line.
