Hi all,
Some time ago, I had seen one patch for hr_timer trigger for=20
asynchronous data acquisition.
A lot of customers use the asynchronous data acquisition to avoid wired=20
interrupt lines.
Can I create in st_sensors library one hr_trigger for this purpose or=20
someone add this patch to the main iio trigger code?
Thanks,
Denis=

Hi,
I've pushed a version of the hr_timer trigger rebased onto iio/togreg to
https://github.com/lclausen-adi/linux-2.6/tree/iio_highres_timer
The trigger works fine, but it needs to be reworked before it can go into
upstream. The issue is that it is currently instantiated via a platform
device while it should be instantiated using some other method, for example
sysfs.
