Is there anything similar out there? We could add a per iio device sysfs interface to add additional mappings but it is a little uggly... > Best idea I can come up with is to disconnect iio_hwmon from the requirement to instantiate it explicitly. There might be two sysfs entries - one to attach it to a specific iio device, and one to attach it to individual channels of an iio device. Similar like the new_device interface on i2c adapters, and along the line of echo max1139 something > /sys/module/iio_hwmon/something_else and/or echo max1139 something channel > /sys/module/iio_hwmon/something_else ie sysfs attributes associated with iio_hwmon, not with the iio device itself. That would require iio_hwmon to be instantiated automatically, though, as soon as it is loaded, not through the iio device or through platform data and/or through devicetree.
