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.
