-* Broadcom Digital Timing Engine(DTE) based PTP clock driver
+* Broadcom Digital Timing Engine(DTE) based PTP clock
 
 Required properties:
-- compatible: should be "brcm,ptp-dte"
+- 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_dte: ptp_dte@180af650 {
-       compatible = "brcm,ptp-dte";
+ptp: ptp-dte@180af650 {
+       compatible = "brcm,iproc-ptp-dte", "brcm,ptp-dte";
        reg = <0x180af650 0x10>;
        status = "okay";
 };
