Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.

Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

Drop description.

Drop "Phandle to a regulator that acts as "

default is 1000, so how constraints can be lower than default? Also -
missing default.
