-* Faraday Technology FTRTC010 Real Time Clock

-This RTC appears in for example the Storlink Gemini family of

-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>;
