From: Arun Parameswaran
Date: Thu Jul 06 2017 - 13:38:54 EST


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";
};
