Can you adjust the frequency of the keystone devices in hardware?  If
so, then please implement it, and just disable PPS for the CPSW.

The only reason I used the timecounter for frequency adjustment was
because the am335x HW is broken.  But this shouldn't hold back other
newer HW without the same silicon flaws.

I am talking here about the ADPLLLJ units.  Are they usable on the
keystone?

If so, please implement the frequency adjustment with them.

No, I think it's not impossible (at least as I know now).
i'll drop this patch for now.

By the way, I've tested am335 (BBB)+ HW_TS_PUSH + PWM.
Seems works.
