If you volunteer to edit content, please ask me and I'll give you edit rights on the document.
Shall we make a github backed document? If so, any volunteer to make it happen?
Agenda for June 24th:
- DT Overlay status presentation by Frank Rowand.
- Document review and trying to close all comments.
Cordially
No pretty slides for my presentation. Here is the outline that I will use. It is mostly based on the information that is contained at the elinux.org links, but the pages at the links have more information.

Status of devicetree overlay support
================================================================================ https://elinux.org/Device_Tree_Reference#Overlays
Run time overlay apply and run time overlay remove from user space are not supported in the mainline kernel.
There are out of tree patches to implement this feature via an overlay manager.
Could you, please, provide a link to the current patches.
I once suggested to implement this via sysfs:
of/overlay: sysfs based ABI for dt overlays https://lore.kernel.org/patchwork/project/lkml/list/?series=296387&state... https://lkml.org/lkml/2016/12/20/510
