Hi Maxime,
I guess a better path forward would be to either register an hwmon device in the original driver, or convert that driver to iio and use iio-hwmon.
My first idea was to add hwmon to sun4i-lradc-keys.c driver. But soon as I began hacking the driver I quickly realized that it would be a mess since keyboard and hwmon belong to two different subsystems. Besides we would need to invent a way to control which way the driver works (new bindings?). So I decided that a new independent small driver would be a better solution.
