[PATCH v8 0/6] of: overlay: kobject & sysfs'ation

[Pantelis Antoniou]

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.
