PSCI reboot mode will map a mode name to multiple magic values instead
of just one. Convert the mode-.* property to an array. Users of the
reboot-mode schema will need to specify the maxItems of the mode-.*
properties. Existing users will all be 1.

You still need to limit total number of items. This only defines how
many items you have in each inner cell of the matrix. What about the
other cell?

I understood that you want something more or less equivalent, but the
code does not look like.



Best regards,
