+* Open PIC Binding
+
+This binding specifies what properties must be available in the device tree
+representation of an Open PIC compliant interrupt controller.  This binding is
+based on the binding defined for Open PIC in [1] and is a superset of that
+binding.
+
+Required properties:
+
+  NOTE: Many of these descriptions were paraphrased here from [1] to aid
+        readability.
+
+    - compatible: Specifies the compatibility list for the PIC.  The type
+      shall be <string> and the value shall include "open-pic".
+
+    - reg: Specifies the base physical address(s) and size(s) of this
+      PIC's addressable register space.  The type shall be <prop-encoded-array>.
+
+    - interrupt-controller: The presence of this property identifies the node
+      as an Open PIC.  No property value shall be defined.
+
+    - #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.
+
+    - #address-cells: Specifies the number of cells needed to encode an
+      address.  The type shall be <u32> and the value shall be 0.  As such,
+      'interrupt-map' nodes do not have to specify a parent unit address.
+
+Optional properties:
+
+    - pic-no-reset: The presence of this property indicates that the PIC
+      shall not be reset during runtime initialization.  No property value shall
+      be defined.  The presence of this property also mandates that any
+      initialization related to interrupt sources shall be limited to sources
+      explicitly referenced in the device tree.
+
+* Interrupt Specifier Definition
+
+  Interrupt specifiers consists of 2 cells encoded as
+  follows:
+
+    - <1st-cell>: The interrupt-number that identifies the interrupt source.
+
+    - <2nd-cell>: The level-sense information, encoded as follows:
+                    0 = low-to-high edge triggered
+                    1 = active low level-sensitive
+                    2 = active high level-sensitive
+                    3 = high-to-low edge triggered
+
+* Examples
+
+Example 1:
+
+        /*
+         * An Open PIC interrupt controller
+         */
+        mpic: pic@40000 {
+                // This is an interrupt controller node.
+                interrupt-controller;
+
+                // No address cells so that 'interrupt-map' nodes which reference
+                // this Open PIC node do not need a parent address specifier.
+                #address-cells = <0>;
+
+                // Two cells to encode interrupt sources.
+                #interrupt-cells = <2>;
+
+                // Offset address of 0x40000 and size of 0x40000.
+                reg = <0x40000 0x40000>;
+
+                // Compatible with Open PIC.
+                compatible = "open-pic";
+
+                // The PIC shall not be reset.
+                pic-no-reset;
+        };
+
+Example 2:
+
+        /*
+         * An interrupt generating device that is wired to an Open PIC.
+         */
+        serial0: serial@4500 {
+                // Interrupt source '42' that is active high level-sensitive.
+                // Note that there are only two cells as specified in the interrupt
+                // parent's '#interrupt-cells' property.
+                interrupts = <42 2>;
+
+                // The interrupt controller that this device is wired to.
+                interrupt-parent = <&mpic>;
+        };

+ * The touchscreen interface operates as follows:
+ *
+ * 1) Pen is pressed against the touchscreen.
+ * 2) TSC2005 performs AD conversion.
+ * 3) After the conversion is done TSC2005 drives DAV line down.
+ * 4) GPIO IRQ is received and tsc2005_irq_thread() is scheduled.
+ * 5) tsc2005_irq_thread() queues up an spi transfer to fetch the x, y, z1, z2
+ *    values.
+ * 6) tsc2005_irq_thread() reports coordinates to input layer and sets up
+ *    tsc2005_penup_timer() to be called after TSC2005_PENUP_TIME_MS (40ms).
+ * 7) When the penup timer expires, there have not been touch or DAV interrupts
+ *    during the last 40ms which means the pen has been lifted.
+ *
+ * ESD recovery via a hardware reset is done if the TSC2005 doesn't respond
+ * after a configurable period (in ms) of activity. If esd_timeout is 0, the
+ * watchdog is disabled.
