[PATCH 00/10] Add sysfs entry for system load control

[Waqar Hameed]

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.
