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.
