Access GPT capture on imx6ull from user space or module

Hello,

I am trying to understand if I am able to use GPT2 for input capture (counting sensor pulses) on my custom imx6 board. From the Linux Reference Manual I can read that GPT is used by linux to enter WFI mode, but I have also found sources saying it is fine to use GPT2?

Any help to clear this out would be appreciated, both if it is possible and how I would go about doing it.

Best regards

Hi @malj

You can refer to this series of patches. Although they are based on the i.MX8MM, the approach is similar for the i.MX6ULL.
