+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";
|
||
|
|
+};
