I think if the specific ARM platform you are working supports a oneshot
clock_device, you would get the high res timer support.
You can check for clock_devices defined in your platform having feature -
CLOCK_EVT_FEAT_ONESHOT.
My guess is that u want to measure the time taken to execute a
function in microseconds.
something like
start_time
YOUR_FUNCTION
end_time
Sorry. I want to measure external pulse on a GPIO pin.
