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.
