In the past it has been determined that the "cap-" prefix is
unnecessary.  Some properties still have "cap-" because of backward
compatibility reasons, but as I understand it new properties shouldn't
start with "cap-".

See <https://lists.ozlabs.org/pipermail/devicetree-discuss/2013-June/034664.html>
for reference.
