Subject: [PATCH net-next v2 0/3] Add PPS support to am65-cpts driver

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.

Changes from v1:
1. Drop device-tree patches.
2. Address Roger's comments on the:
   "net: ethernet: ti: am65-cpts: add pps support" patch.
3. Collect Reviewed-by tag from Rob Herring.
