03f9c40e7d
The change adds a new mode property allowed_mode_switch. The new property is a 32bit bitmask that indicates the modes each mode can switch to. This change is required to pass the driver mode switching capabilities, so that user mode can reject any mode switch that is not supported by the driver.
