What if we want some higher opp for some reason? The point of v1 and v2 was oonly to require required-opps on certain variants, not to disallow it in other cases. Best regards, Krzysztof

On SM8650, the minimum voltage corner supported on MMCX from cmd-db is sufficient for clock controllers to operate and there is no need to specify the required-opps. Hence remove the required-opps property from the list of required properties for SM8650 camcc and videocc bindings.
