DT properties which can have multiple entries need to specify what the entries are and define how many entries there can be. In the case of only a single entry, just 'maxItems: 1' is sufficient. Add the missing entry constraints. These were found with a modified meta-schema. Unfortunately, there are a few cases where the size constraints are not defined such as common bindings, so the meta-schema can't be part of the normal checks.

The BQ25980, BQ25975, and BQ25960 are a series of flash chargers intended
|
|
for use in high-power density portable electronics. These inductorless
|
|
switching chargers can provide over 97% efficiency by making use of the
|
|
switched capacitor architecture.
