Can you m= ake > a patch series where the driver change appears in the second patch? Hi Richard/Jacob Thanks for the review. Unfortunately, I don't have the patch based on the=20 Existing PHC driver. But I have a brand new PHC driver for our new timing HW that implements=20 the feature. The measurement is done by the HW using the=20 Time to Digital Converter (TDC) that performs the function of a stopwatch a= nd=20 measures the elapsed time between a START pulse and STOP pulses. So I have GNSS 1pps input to the HW and TDC will perform continuous measurement between the input 1pps and the 1pps of the onboard PHC. I also have the ts2phc patch ready along with the PHC change. I already=20 tested them on our HW and proved that ts2phc can align the 2 signal using=20 the existing PI filter. Please let me know how you wanna proceed. Do you want me to attach the new PHC with this patch? Min
