i.MX 8M Mini - Are clocks synchronized across Cortex A and Cortex M?

I have an i.MX 8M Mini EVK, and I'm running Linux on the Cortex A53 and was planning on running FreeRTOS on the Cortex M4. I was curious, if I'm doing stuff on the Cortex A53, like changing the wall-clock time via Linux (think synchronizing its wall clock to a master clock source), does that change propagate to the Cortex M4 running FreeRTOS? 

 

If not, how would you reliably synchronize the two clocks to run in step with each other?

 

Thanks.
