* 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";
};
