The CPTS hardware doesn't support PPS signal generation. Using the GenFx
(periodic signal generator) function, it is possible to model a PPS signal
followed by routing it via the time sync router to the CPTS_HWy_TS_PUSH
(hardware time stamp) input, in order to generate timestamps at 1 second
intervals.

This series adds driver support for enabling PPS signal generation.
Additionally, the documentation for the am65-cpts driver is updated with
the bindings for the "ti,pps" property, which is used to inform the
pair [CPTS_HWy_TS_PUSH, GenFx] to the cpts driver. The PPS example is
enabled for AM625-SK board by default, by adding the timesync_router node
to the AM62x SoC, and configuring it for PPS in the AM625-SK board dts.

Device tree patches need to be sent separately. You don't need to involve
net maintainers for that.

If you introduce a new binding then that needs to be in maintainer's
tree before you can send a related device tree patch.

Thank you for letting me know. Would I need to resend the series in order for it
to be reviewed? I was hoping that if I get feedback for this series, I will
implement it and post just the bindings and driver patches as the v2 series,
dropping the device tree patches. Please let me know.

Regards,
Siddharth.

You could wait a couple of days for more comments here before spinning off a v2 ;)
