ARM Global timer of iMX6QSD

Dear Sir,

 

By Cortex ™ -A9 MPCore Technical Reference Manual, the global timer is clocked by PERIPHCLK. I don't know which clock is it in  iMX6QSD CCM Clock Tree.

By my test  the clock frequency of ARM global timer is changed when I change ARM clock frequency for DVFS. So I guess the clock of the global timer may be ARM_CLK_ROOT. Is it correct?

What is the clock frequency of ARM global timer?

 

Thanks,

Miles
