+DT bindings for the R-/SH-Mobile irqpin controller
+
+Required properties:
+
+- compatible: has to be "renesas,intc-irqpin-<soctype>", "renesas,intc-irqpin"
+  as fallback.
+  Examples with soctypes are:
+    - "renesas,intc-irqpin-r8a7740" (R-Mobile A1)
+    - "renesas,intc-irqpin-r8a7778" (R-Car M1A)
+    - "renesas,intc-irqpin-r8a7779" (R-Car H1)
+    - "renesas,intc-irqpin-sh73a0" (SH-Mobile AG5)
+
+- reg: Base address and length of each register bank used by the external
+  IRQ pins driven by the interrupt controller hardware module. The base
+  addresses, length and number of required register banks varies with soctype.
+
+- #interrupt-cells: has to be <2>: an interrupt index and flags, as defined in
+  interrupts.txt in this directory
+
+Optional properties:
+
+- any properties, listed in interrupts.txt, and any standard resource allocation
+  properties
+- sense-bitfield-width: width of a single sense bitfield in the SENSE register,
+  if different from the default 4 bits
+- control-parent: disable and enable interrupts on the parent interrupt
+  controller, needed for some broken implementations
