Subject[PATCH v1 1/1] dt-binding: ptp: Add SoC compatibility strings for dte ptp clock
Date
Add SoC specific compatibility strings to the Broadcom DTE
based PTP clock binding document.

Fixed the document heading and node name.

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";
};
