ChangeLog v1->v2:
- Rename required property "intcon" to "interrupt-controller"
- Elaborate a bit on the SoC origins
- Put the example DTS SoC nodes in a soc {} node

interrupt-controller maybe ? ;)

+Cortina systems Gemini platforms
+
+The Gemini SoC is the project name for an ARMv4 FA525-based SoC originally
+produced by Storlink Semiconductor around 2005. The company was renamed
+later renamed Storm Semiconductor. The chip product name is Storlink SL3516.
+It was derived from earlier products from Storm named SL3316 (Centroid) and
+SL3512.
+
+Storm Semiconductor was acquired by Cortina Systems in 2008 and the SoC was
+produced and used for NAS and similar usecases. In 2014 Cortina Systems was
+in turn acquired by Inphi, who seem to have discontinued this product family.
+
+Required properties (in root node):
+	compatible = "cortina,gemini";
+
+Required nodes:
+
+- syscon: the root node must have a system controller node pointing to the
+  global control registers, with the compatible string
+  "cortina,gemini-syscon", "syscon";
+
+- timer: the root node must have a timer node pointing to the SoC timer
+  block, with the compatible string "cortina,gemini-timer"
+  See: clocksource/cortina,gemini-timer.txt
+
+- interrup-controller: the root node must have an interrupt controller
+  node pointing to the SoC interrupt controller block, with the compatible
+  string "cortina,gemini-interrupt-controller"
+  See interrupt-controller/cortina,gemini-interrupt-controller.txt
+
+Example:
+
+/ {
+	model = "Foo Gemini Machine";
+	compatible = "cortina,gemini";
+	#address-cells = <1>;
+	#size-cells = <1>;
+
+	memory {
