++Device-Tree bindings for MediaTek SoC based RTC
++
++Required properties:
++- compatible      : Should be
++                      "mediatek,mt7622-rtc", "mediatek,soc-rtc" : for MT7622 SoC
++- reg                     : Specifies base physical address and size of the registers;
++- interrupts      : Should contain the interrupt for RTC alarm;
++- clocks          : Specifies list of clock specifiers, corresponding to
++                    entries in clock-names property;
++- clock-names     : Should contain "rtc" entries
++
++Example:
++
++rtc: rtc@10212800 {
++      compatible = "mediatek,mt7622-rtc",
++                   "mediatek,soc-rtc";
++      reg = <0 0x10212800 0 0x200>;
++      interrupts = <GIC_SPI 129 IRQ_TYPE_LEVEL_LOW>;
++      clocks = <&topckgen CLK_TOP_RTC>;
++      clock-names = "rtc";
++};
