imx 6 +  periodic timer + linux

I'm using a imx 6 sabrelite board with the linux kernel (yocto project "dora release").

I want to call a function 64 times per second with this ARM processor.

Ideally, I don't want too much jitter. I want to perform a task periodically... (ie: scanning a device)

I'm thinking to use a timer of the 6 and generate an interrupt 64 times per second ? (EPIT timer?)


Is it possible to do that with yocto and the imx 6 ?

Can somebody give me some examples or let me know where I can find documentation about this ?

Where can I find examples on the usage of the EPIT timer ?
