1* Faraday Technology FTRTC010 Real Time Clock
2
3This RTC appears in for example the Storlink Gemini family of
4SoCs.
5
6Required properties:
7- compatible : Should be one of:
8 "faraday,ftrtc010"
9 "cortina,gemini-rtc", "faraday,ftrtc010"
10
11Optional properties:
12- clocks: when present should contain clock references to the
13 PCLK and EXTCLK clocks. Faraday calls the later CLK1HZ and
14 says the clock should be 1 Hz, but implementers actually seem
15 to choose different clocks here, like Cortina who chose
16 32768 Hz (a typical low-power clock).
17- clock-names: should name the clocks "PCLK" and "EXTCLK"
18 respectively.

20Examples:
21
22rtc@45000000 {
23 compatible = "cortina,gemini-rtc";
24 reg = <0x45000000 0x100>;
25 interrupts = <17 IRQ_TYPE_LEVEL_HIGH>;
26 clocks = <&foo 0>, <&foo 1>;
27 clock-names = "PCLK", "EXTCLK";
28};
