Hello.
Probably over a year ago i built a rasperry pi and made a custom build
of openwrt and added a small patch for myself to make module for htu21
temp and humidity sensor available.
the patch i made i'm not sure if it is correct or not and even if it
still works with all the changes that has been done but it would be
nice to have the kernel module (kmod-iio-htu21) built and available as
an option preferably in some future release.
i use the htu21 kernel module with a small shell script to push the
data out to an mqtt server for further handling.
there is probably more iio modules that could be useful to others but
for now i'm happy if i can make a new version of openwrt with the
kernel module added and preferably also get it included so i don't
need a custom build.
below is my old patch.
Patch looks ok at first glance, but there are a few formal errors, the
Signed-off-by is missing and the patch headline needs to be prefixed and
a proper description needs to be written ->
