867 | * standardized properties (even for extensions beyond the core set of | |
868 | * properties which might not be implemented by all drivers) this | |
869 | * requires drivers to subclass the state structure. | |
870 | * | |
871 | * Such driver-private properties should really only be implemented for | |
872 | * truly hardware/vendor specific state. Instead it is preferred to | |

886 | * userspace's request to just check whether a configuration would be | |
887 | * possible). Drivers MUST NOT touch any persistent state (hardware or | |
888 | * software) or data structures except the passed in @state parameter. | |
889 | * | |
890 | * Also since userspace controls in which order properties are set this | |
891 | * function must not do any input validation (since the state update is | |
892 | * incomplete and hence likely inconsistent). Instead any such input | |
893 | * validation must be done in the various atomic_check callbacks. | |
