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

for reference.
Really? was that the final decision? I just see Olof complained it but
don't see other comments from dt maintainer or from mmc
maintainer(Chris Ball)?
Hi Ulf and Rob,
What is your opinion?
