| | | | | | | | | | | | | | | | | | | Allow setting frequency below 1Hz or sub 1Hz precision. Useful for slow sensors like ALS. Test frequency is set properly: modprobe iio-trig-hrtimer && \ mkdir /sys/kernel/config/iio/triggers/hrtimer/t1 && \ cd /sys/bus/iio/devices/triggerX ; for i in 1 .1 .01 .001 ; do echo $i > sampling_frequency cat sampling_frequency done Signed-off-by: Gwendal Grignou <gwendal@chromium.org> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Link: https://lore.kernel.org/r/20210226014733.2108544-1-gwendal@chromium.org Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

* docs: filesystems: convert configfs.txt to ReSTMauro Carvalho Chehab2020-05-051-1/+1
| | | | | | | | | | | | | | | | | - Add a SPDX header; - Adjust document and section titles; - Use copyright symbol; - Some whitespace fixes and new line breaks; - Mark literal blocks as such; - Add it to filesystems/index.rst. Also, as this file is alone on its own dir, and it doesn't seem too likely that other documents will follow it, let's move it to the filesystems/ root documentation dir.

| | | | | | | | | | | | Rename the iio documentation files to ReST, add an index for them and adjust in order to produce a nice html output via the Sphinx build system. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.
