  21 +Device-Tree bindings for MediaTek SoC based RTC
  22 +
  23 +Required properties:
  24 +- compatible       : Should be
  25 +                       "mediatek,mt7622-rtc", "mediatek,soc-rtc" : for MT7622 SoC
  26 +- reg              : Specifies base physical address and size of the registers;
  27 +- interrupts       : Should contain the interrupt for RTC alarm;
  28 +- clocks           : Specifies list of clock specifiers, corresponding to
  29 +                     entries in clock-names property;
  30 +- clock-names      : Should contain "rtc" entries
  31 +
  32 +Example:
  33 +
  34 +rtc: rtc@10212800 {
  35 +       compatible = "mediatek,mt7622-rtc",
  36 +                    "mediatek,soc-rtc";
  37 +       reg = <0 0x10212800 0 0x200>;
  38 +       interrupts = <GIC_SPI 129 IRQ_TYPE_LEVEL_LOW>;
  39 +       clocks = <&topckgen CLK_TOP_RTC>;
  40 +       clock-names = "rtc";
  41 +};
