Config_iio_hrtimer_trigger

**Hello **
We are working with an accel chip from ST lis2dw12 and in our application with the iio lib framework. At the moment we are working with sysfs trigger. Because of jitter we wanna change to hrt trigger. Looking at the kernel config I cannot see the CONFIG_IIO_HRTIMER_TRIGGER that we need. Would it be possible to include that in the Kernel?
Here our actual info:Software summary

Hello @pitschen,

Sorry about the delay in answering. The support team is currently busy with an internal event.

I requested the Torizon OS team to enable this kernel config for you. They are evaluating its impact on Torizon OS. If everything goes will, it should be done in 3-4 days and should be available on the nightly builds. I will notify you when that’s done.

Thank you for your patience.
