[PATCH v2 2/2] dt-bindings: opp: opp-v2-kryo-cpu: enlarge opp-supported-hw maximum

From: Christian Marangi
Date: Sun Jan 22 2023 - 12:46:05 EST


Enlarge opp-supported-hw maximum value. In recent SoC we started
matching more bit and we currently match mask of 112. The old maximum of
7 was good for old SoC that didn't had complex id, but now this is
limiting and we need to enlarge it to support more variants.

Document all the various mask that can be used and limit them to only
reasonable values instead of using a generic maximum limit.
