The first patch puts the overlays as objects in the sysfs in /sys/firmware/devicetree/overlays. The #2 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 patch following is the ABI docs for the sysfs entries of #2, while the next one updates the doc entry for the kernel parameter of_overlay_disable. Patch #5 add per overlay sysfs attributes, and the next one is documentation about it. The patchset is against linus's tree as of today. Changes since v6: * Updated changelogs as per maintainer suggestion. * Fixed documentation entries and split them up * Added command line parameter docs. Changes since v5: * Does a single kobject_put that suffices * A per-fragment sysfs directory and a single value target. * Update in the ABI documention. Changes since v4: * Rebased against latest mainline. 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.
