+* Broadcom Digital Timing Engine(DTE) based PTP clock
+
+Required properties:
+- compatible: should contain the core compatibility string
+ and the SoC compatibility string. The SoC
+ compatibility string is to handle SoC specific
+ hardware differences.
+ Core compatibility string:
+ "brcm,ptp-dte"
+ SoC compatibility strings:
+ "brcm,iproc-ptp-dte" - for iproc based SoC's
+- reg: address and length of the DTE block's NCO registers
+
+Example:
+
+ptp: ptp-dte@180af650 {
+ compatible = "brcm,iproc-ptp-dte", "brcm,ptp-dte";
+ reg = <0x180af650 0x10>;
+};
