If I look for example at the camera module drivers provided by drivers/media/i2c, most of them could be easily power-controlled from user-space by i2c-tools and 1-2 gpios through /sys/class/gpio and a big set of scripts.
Still they have a place in the kernel and cameras are powered on if the device is opened and powered down if it is closed.
So I am still trying to understand the rationale and logic (if one exists) behind having them in kernel but rejecting our driver which does the same for a different class of devices.
For media we have a framework in place; for gps we do not (yet).
