Subject: [PATCH v1 1/1] dt-binding: ptp: Add SoC compatibility strings for dte ptp clock
Add SoC specific compatibility strings to the Broadcom DTE
based PTP clock binding document.
Fixed the document heading and node name.
Fixes: 80d6076140b2 ("dt-binding: ptp: add bindings document for dte based ptp clock")

-* 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@...af650 {
- compatible = "brcm,ptp-dte";
+ptp: ptp-dte@...af650 {
+ compatible = "brcm,iproc-ptp-dte", "brcm,ptp-dte";
reg = <0x180af650 0x10>;
status = "okay";
};
