The Gemini RTC is actually a standard IP block from Faraday
Technology called FTRTC010. Rename the bindings, add the
generic compatible string and add definitions for the two
available clocks.

+* Faraday Technology FTRTC010 Real Time Clock
+
+This RTC appears in for example the Storlink Gemini family of
+SoCs.
+
+Required properties:
+- compatible : Should be one of:
+ "faraday,ftrtc010"
+ "cortina,gemini-rtc", "faraday,ftrtc010"
+
+Optional properties:
+- clocks: when present should contain clock references to the
+ PCLK and EXTCLK clocks. Faraday calls the later CLK1HZ and
+ says the clock should be 1 Hz, but implementers actually seem
+ to choose different clocks here, like Cortina who chose
+ 32768 Hz (a typical low-power clock).
+- clock-names: should name the clocks "PCLK" and "EXTCLK"
+ respectively.
+
+Examples:
+
+rtc@45000000 {
+ compatible = "cortina,gemini-rtc";
+ reg = <0x45000000 0x100>;
+ interrupts = <17 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&foo 0>, <&foo 1>;
+ clock-names = "PCLK", "EXTCLK";
+};
