During discussions of the development of a new driver [1], it was concluded that a new `sysfs` ABI for controlling the connection from power to system load is wanted (often called BATFET). This patchset introduces such one.
There are already several drivers that are controlling this, but with their own custom `sysfs` entries. The drivers in this patchset were find with a simple `grep` for `bat\s?fet` (there might be more?), and then converted to use this new `sysfs` ABI. The old custom ABIs are left untouched of course, for backward compatibility.
