+NXP PCF2127 SPI Real Time Clock
+
+Required properties:
+- compatible: should be: "nxp,pcf2127"
+                      or "nxp,pcf2129"
+- reg: should be the SPI slave chipselect address
+
+Optional properties:
+- no-watchdog: PCF2127 is not used as watchdog
+
+Example:
+
+pcf2127: rtc@51 {
+	compatible = "nxp,pcf2127";
+	reg = <0x51>;
+	interrupts = <0 150 0x4>;
+	no-watchdog;
