…ccess vcio has a number of uses, including clocks and power, board info, gencmd, display, vpu execution, provisioning, crypto, ab booting. Currently we have to give a user access to all or none of these. Provide some additional nodes which can only access a subset of these commands. That allows, say, gencmd access from a user or group, without exposing more dangerous commands. The initial extra nodes are for gencmd, provisioning, ab and crypto.
