+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 (Bulverde).
+
+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.
+
+Many of the IP blocks used in the SoC comes from Faraday Technology.
+
+Required properties (in root node):
+ compatible = "cortina,gemini";
+
+Required nodes:
+
+- soc: the SoC should be represented by a simple bus encompassing all the
+ onchip devices, this is referred to as the soc bus node.
+
+- syscon: the soc bus node must have a system controller node pointing to the
+ global control registers, with the compatible string
+ "cortina,gemini-syscon", "syscon";
+
+- timer: the soc bus 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
+
+- interrupt-controller: the sob bus 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 {
+ device_type = "memory";
+ reg = <0x00000000 0x8000000>;
+ };
+
+ soc {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+ compatible = "simple-bus";
+ interrupt-parent = <&intcon>;
+
+ syscon: syscon@40000000 {
+ compatible = "cortina,gemini-syscon", "syscon";
+ reg = <0x40000000 0x1000>;
+ };
+
+ uart0: serial@42000000 {
+ compatible = "ns16550a";
+ reg = <0x42000000 0x100>;
+ clock-frequency = <48000000>;
+ interrupts = <18 IRQ_TYPE_LEVEL_HIGH>;
+ reg-shift = <2>;
+ };
+
+ timer@43000000 {
+ compatible = "cortina,gemini-timer";
+ reg = <0x43000000 0x1000>;
+ interrupt-parent = <&intcon>;
+ interrupts = <14 IRQ_TYPE_EDGE_FALLING>, /* Timer 1 */
+ <15 IRQ_TYPE_EDGE_FALLING>, /* Timer 2 */
+ <16 IRQ_TYPE_EDGE_FALLING>; /* Timer 3 */
+ syscon = <&syscon>;
+ };
+
+ intcon: interrupt-controller@48000000 {
+ compatible = "cortina,gemini-interrupt-controller";
+ reg = <0x48000000 0x1000>;
