Enabling overlayfs/DTO

I'm having some trouble enabling overlayfs on my board.  It's running vanilla mainline Linux with just a couple patches for emmc.
I have configfs and overlayfs enabled, but the device-tree directory doesn't populate in /sys/kernel/config.
My understanding of overlayfs is a bit hazy, so I'm confused whether this device-tree directory is provided by a separate driver or patchset found in the ayufan kernel, or if it needs to be mounted manually. This guide that I was following shows that the directory is automatically found in /sys/kernel/config when it's mounted, again not sure if that feature is provided by the custom kernel they are using...
In terms of mounting, I am pretty confused by the documentation in https://www.kernel.org/doc/Documentation...rlayfs.txt.
