+Faraday Technology timer
+
+This timer is a generic IP block from Faraday Technology, embedded in the
+Cortina Systems Gemini SoCs and other designs.
+
+Required properties:
+
+- compatible : Must be one of
+ "faraday,fttmr010"
+ "cortina,gemini-timer", "faraday,fttmr010"
+ "moxa,moxart-timer", "faraday,fttmr010"
+ "aspeed,ast2400-timer"
+ "aspeed,ast2500-timer"
+ "aspeed,ast2600-timer"
+
+- reg : Should contain registers location and length
+- interrupts : Should contain the three timer interrupts usually with
+ flags for falling edge
+
+Optionally required properties:
+
+- clocks : a clock to provide the tick rate for "faraday,fttmr010"
+- clock-names : should be "EXTCLK" and "PCLK" for the external tick timer
+ and peripheral clock respectively, for "faraday,fttmr010"
+- syscon : a phandle to the global Gemini system controller if the compatible
+ type is "cortina,gemini-timer"
+
+Example:
+
+timer@43000000 {
+ compatible = "faraday,fttmr010";
+ reg = <0x43000000 0x1000>;
+ interrupts = <14 IRQ_TYPE_EDGE_FALLING>, /* Timer 1 */
+ <15 IRQ_TYPE_EDGE_FALLING>, /* Timer 2 */
+ <16 IRQ_TYPE_EDGE_FALLING>; /* Timer 3 */
+ clocks = <&extclk>, <&pclk>;
+ clock-names = "EXTCLK", "PCLK";
+};
