The first patch puts the overlays as objects in the sysfs in
/sys/firmware/devicetree/overlays.
The next adds a master overlay enable switch (that once is set to
disabled can't be re-enabled), while the one after that
introduces a number of default per overlay attributes.
The patchset is against linus's tree as of today.
The last patch updates the ABI docs for the sysfs entries.
Changes since v3:
* Used strtobool instead of kstrtoul
* ABI Documentation includes a pointer to the discussion that
requested the sysfs property.
Changes since v2:
* Removed the unittest patch.
* Split the sysfs attribute patch to a global and a per-overlay
patch.
* Dropped binary attributes using textual kobj_attributes instead.
Changes since v1:
* Maintainer requested changes.
* Documented the sysfs entries
* Per overlay sysfs attributes.
