MOXA ART real-time clock Required properties: - compatible : Should be "moxa,moxart-rtc" - gpio-rtc-sclk : RTC sclk gpio, with zero flags - gpio-rtc-data : RTC data gpio, with zero flags - gpio-rtc-reset : RTC reset gpio, with zero flags Example: rtc: rtc { compatible = "moxa,moxart-rtc"; gpio-rtc-sclk = <&gpio 5 0>; gpio-rtc-data = <&gpio 6 0>; gpio-rtc-reset = <&gpio 7 0>; };
